The　present　study　reports　a　simple,　effective　and　energy-efficient　method　to　prepare　gamma-LiAlO2　powder　as　a　matrix　in　a　molten　carbonate　fuel　cell　(MCFC).　In　our　experiments,　aqueous　solution　based　sol-gel　technique　was　used　to　synthesize　gamma-LiAlO2.　Highly　dispersed　AlOOH　center　dot　nH(2)O　and　LiOH　center　dot　H2O　aqueous　solutions　were　mixed　to　form　a　colloid　mixture,　which　was　calcined　to　synthesize　gamma-LiAlO2.　Thermogravimetric　analysis　(TGA),　X-ray　diffraction　(XRD),　and　scanning　electron　microscopy　(SEM)　were　used　to　study　the　composition　and　morphology　of　the　intermediate　and　final　products.　The　analysis　results　showed　that　an　intermediate　product　Li2Al4CO3(OH)(12)　was　produced　after　the　colloid　mixture　was　dried　at　80　degrees　C,　and　highly　purified　gamma-LiAlO2　powder　with　fine　particle　size　was　resulted　from　the　subsequent　calcinations.　A　single　MCFC　was　assembled　with　a　matrix　of　the　gamma-LiAlO2　powder.　The　testing　results　showed　that　the　matrix　performed　well　in　preventing　gas　leakage.
