Harvesting waste heat energy by promoting H+-ion concentration difference with a fuel cell structure EI SCIE

Abstract&Keyword Cite

Abstract :

Energy consumption continues to rise as society develops worldwide. Meanwhile, a lot of energy is wasted in the form of heat from various devices and systems. Here we report a new power generator, which works based on a difference in H+-ion concentration in a fuel cell structure and produces electricity by harvesting waste heat. The device works via the following three successive processes: H2 is oxidized at anode to H+ ions, the H+ ions then penetrate through a phosphoric acid-treated polybenzimidazole (PBI-PA) membrane and finally the H+ ions get reduced to H2 at cathode with electrons coming through external circuit from the anode. This system generates electricity at a current density of 21 mA cm−2 and a power density of 1.03 mW cm−2 at 170 °C. The cell's thermoelectric conversion efficiency at 170 °C is 13.72%, which is higher than typical values reported for many common thermoelectric materials in low temperature regimes. This innovative approach may allow for efficient generation of electricity from waste heat. © 2018 Elsevier Ltd

Abstract :

In the present paper, a patching type multi-block lattice Boltzmann method is adopted to predict the thermal contact resistance (TCR) at the interface of two solids. The rough surfaces of contact materials are reconstructed based on the fractal theory and the contact pressure is obtained based on the plastic deformation model. The accuracy of the patching type multi-block lattice Boltzmann method is validated by some benchmarks. After validations, effects of the contact pressure, roughness, thermal conductivity of contact material, thermal conductivity of interstitial medium, temperature and radiation on TCR are investigated. The results show that: the TCR decreases when the contact pressure increases, but increases with the root-mean-square roughness; the TCR of two contact aluminums decreases faster than that of stainless steels when contact pressure increases; a higher thermal conductivity of contact materials leads to a smaller TCR; when the thermal conductivity of interstitial medium is close to zero or the gap is in vacuum, the TCR is much larger than that filled with air, especially at low contact pressure; at the high temperature, the contribution of the radiation to the TCR becomes appreciable if the thermal conductivity of the interstitial medium is low. Especially when the gap is in vacuum, the contribution of radiation on the TCR cannot be neglected.

Abstract :

Nucleate boiling heat transfer (NBHT) from enhanced structures is an effective way to dissipate a high heat flux. In the present study, the behavior of cavities with nucleation on roughened surfaces is studied numerically during the entire ebullition cycle based on the phase-change lattice Boltzmann method. The adopted model is firstly validated by the Laplace law and the two-phase coexistence curve and then is applied to investigate the effects of the cavity structure on NBHT. The bubble departure diameter, departure frequency, and the total boiling heat flux of the ebullition cycle are also studied. It is shown that the cavity widths and the cavity grooves exhibit a significant influence on the NBHT features. A cavity with a circular groove in the present research shows the best performance for NBHT in terms of the averaged heat flux and bubble release frequency. When a specific cavity is combined with other different cavities on roughened surfaces, its nucleation process on different roughened surfaces may differ greatly.

Abstract :

Solubility trapping is crucial for permanent CO 2 sequestration in deep saline aquifers. For the first time, a pore-scale numerical method is developed to investigate coupled scCO(2)-water two-phase flow, multicomponent (CO2(aq), H+, HCO3, CO32- and OH ) mass transport, heterogeneous interfacial dissolution reaction, and homogeneous dissociation reactions. Pore-scale details of evolutions of multiphase distributions and concentration fields are presented and discussed. Time evolutions of several variables including averaged CO2(aq) concentration, scCO(2) saturation, and pH value are analyzed. Specific interfacial length, an important variable which cannot be determined but is required by continuum models, is investigated in detail. Mass transport coefficient or efficient dissolution rate is also evaluated. The pore-scale results show strong non-equilibrium characteristics during solubility trapping due to non-uniform distributions of multiphase as well as slow mass transport process. Complicated coupling mechanisms between multiphase flow, mass transport and chemical reactions are also revealed. Finally, effects of wettability are also studied. The pore-scale studies provide deep understanding of non-linear non-equilibrium multiple physicochemical processes during CO2 solubility trapping processes, and also allow to quantitatively predict some important empirical relationships, such as saturation-interfacial surface area, for continuum models.

Abstract :

For applications of reactive transport in porous media, optimal porous structures should possess both high surface area for reactive sites loading and low mass transport resistance. Hierarchical porous media with a combination of pores at different scales are designed for this purpose. Using the lattice Boltzmann method, pore-scale numerical studies are conducted to investigate diffusion-reaction processes in 2D hierarchical porous media generated by self-developed reconstruction scheme. Complex interactions between porous structures and reactive transport are revealed under different conditions. Simulation results show that adding macropores can greatly enhance the mass transport, but at the same time reduce the reactive surface, leading to complex change trend of the total reaction rate. Effects of gradient distribution of macropores within the porous medium are also investigated. It is found that a front-loose, back-tight (FLBT) hierarchical structure is desirable for enhancing mass transport, increasing total reaction rate, and improving catalyst utilization. On the whole, from the viewpoint of reducing cost and improving material performance, hierarchical porous structures, especially gradient structures with the size of macropores gradually decreasing along the transport direction, are desirable for catalyst application.

Abstract :

In this paper, the through-plane and in-plane effective transport properties, including permeability, diffusivity and thermal conductivity, of the perforated gas diffusion layer (GDL) are predicted using multiple-relaxation-time (MRT) lattice Boltzmann method (LBM) based on stochastic reconstructed microstructures. When predicting effective thermal conductivities of GDL, the effect of anisotropic conductive property of fibers is considered. The effective transport properties of dry perforated GDL are fitted as a function of perforation diameter and porosity. It is found that the permeability and effective diffusivity of GDL increase with perforation diameter and porosity while the effective thermal conductivity decreases. The two-phase LBM is adopted to simulate water distributions in perforated GDLs, and dependences of effective transport properties on saturation are then obtained. The results show that: the existence of the perforation significantly affects the water transport in hydrophobic perforated GDLs if its diameter is larger than the average pore size of GDL. The effective permeability and diffusivity of GDL decrease while effective thermal conductivity increases with saturation. The effective transport properties of perforated GDLs change less significantly with saturation than those of non-perforated GDL if the water droplet intruding into the perforation is displaced, while change more rapidly with saturation if the water droplet remains inside the perforation.

Abstract :

Reducing Platinum amount in proton exchange membrane fuel cell (PEMFC) is one of the main tasks to achieve low cost PEMFC. Recently, significant performance loss has been found under low Pt loading due to local mass transport limitations. In this study, pore-scale simulations are conducted to study oxygen transport within four-constituent microscopic structures of catalyst layer including a carbon particle, ionomer, Pt particles, and primary pores inside the carbon particle. Multiphase physicochemical processes are considered, including oxygen dissolution at the pore/ionomer interface, oxygen diffusion within the ionomer film and inside the primary pores, and reactions at the Pt interface. Local transport resistance is calculated based on the pore-scale concentration field predicted. The simulation results are compared with existing experimental results and 1D models. Simulation results show that dissolution resistance at the secondary pore/ionomer interface is about 10–50 times higher than that inside the ionomoer. Local transport resistance increases as Pt loading decreases, especially under Pt loading of 0.1 mg cm−2. Besides, local transport resistance can be reduced by depositing more Pt outside the carbon particle, alleviating agglomeration and/or decreasing the ionomer thickness. The simulation results indicate that local transport characteristics should be considered when developing 1D agglomeration model of catalyst layer. © 2018 Elsevier B.V.

Abstract :

Nucleate boiling heat transfer (NBHT) from enhanced structures is an effective way to dissipate high heat flux. In the present study, a 3D multi-relaxation-time (MRT) phase-change lattice Boltzmann method in conjunction with conjugated heat transfer treatment is proposed and then applied to the study of cavities behaviours for nucleation on roughened surfaces for an entire ebullition cycle without introducing any artificial disturbance. The bubble departure diameter, departure frequency and total boiling heat transfer rate are also explored. It is demonstrated that the cavity shapes show significant influence on the features of NBHT. The total heat transfer rate increases with the cavity mouth and cavity base area while decreases with the increase in cavity bottom wall thickness. The cavity with low wetting can enhance the heat transfer and improve the bubble release frequency. (C) 2016 Elsevier Ltd. All rights reserved.

Abstract :

Recent studies have shown that adsorbed gas and its surface diffusion have profound influence on micro gaseous flow through organic pores in shale gas reservoirs. In this paper, a multiple-relaxation-time (MRT) LB model is adopted to estimate the apparent permeability of organic shale and a new boundary condition, which combines Langmuir adsorption theory with Maxwellian diffusive reflection boundary condition, is proposed to capture gas slip and surface diffusion of adsorbed gas. The simulation results match well with previous studies carried out using Molecular Dynamics (MD) and show that Maxwell slip boundary condition fails to characterize gas transport in the near wall region under the influence of the adsorbed gas. The total molar flux can be either enhanced or reduced depending on variations in adsorbed gas coverage and surface diffusion velocity. The effects of pore width, pressure as well as Langmuir properties on apparent permeability of methane transport in organic pores are further studied. It is found that the surface transport plays a significant role in determining the apparent permeability, and the variation of apparent permeability with pore size and pressure is affected by the adsorption and surface diffusion.

Abstract :

In the present paper, a 2D multiple-relaxation-time pseudopotential lattice Boltzmann model combined with the modified thermal lattice Boltzmann method is adopted to simulate the bubble nucleation, growth and departures process on a heated plate. It is a direct numerical simulation of boiling heat transfer determined by the local temperature and thermodynamic relation given by the equation of state. By using a smaller value of a in the P-R equation of state, a thicker liquid-vapor interface is formed and a better numerical stability at a large liquid/vapor density ratio is obtained. Furthermore, the conjugated boundary of heated plate and fluids is specially dealt with to avoid the rapid change of heat flux at the interface. The boiling heat transfer at a density ratio around 200 can be simulated. The results show that: the boiling heat flux decreases during the bubble expansion process while increases during the rewetting process; the average heat flux of boiling at T-s = 0.68T(c) is much larger than that at T-s = 0.86T(c); bubble occurs earlier on a hydrophobic surface than a hydrophilic one; there exists a remained vapor on a hydrophobic surface after bubble departure, while it is not observed for hydrophilic surface; for the simulated boiling curve, the maximum (critical) heat flux decreases with the decreasing wettability of surfaces; there exists an optimal width of the rectangular cavity making the best heat transfer performance of surfaces; in this study, the roughness surface with a circle cavity has the best heat transfer performance.
