In　this　work,　an　amorphous　Ni-B　alloy　was　synthesized　by　chemical　reduction　and　used　in　a　direct　borohydride　fuel　cell　(DBFC).　Characterization　of　the　catalyst　structure,　composition,　and　morphology　was　performed　by　XRD,　EDX,　TEM,　and　SEM.　In　addition,　the　results　showed　that　Ni-B　presents　as　amorphous　nanoparticles.　The　particle　diameters　ranged　from　22　to　25　nm.　The　cyclic　voltammetry　(CV)　and　chronoamperometry　(CA)　tests　proved　that　Ni-B　has　better　electrocatalytic　activity　and　higher　stability　towards　KBH4　oxidation　compared　to　a　pure　Ni　catalyst.　A　single　cell　was　assembled　with　a　Ni-B　anode　and　a　LaNi0.9Ru0.1O3　cathode.　A　peak　power　density　of　180　mW　cm(-2)　was　achieved　at　room　temperature.　In　addition,　the　fuel　utilization　rate　was　approximately　41%　at　a　constant　current　density　of　200　mA　cm(-2),　illustrating　that　some　BH4　(-)　hydrolysis　occurs　on　the　Ni-B　surface.　Finally,　the　cell　had　no　attenuation　after　180　h　test,　showing　good　stability.
