Electrode materials for intermediate temperature proton-conducting fuel cells

Some electrode materials for intermediate temperature proton-conducting fue l cells are analysed from the perspective of surface reaction and ionic con ductivity type. The performance of H-2/O-2 fuel cells using these materials as electrodes with LiNaSO4-Al2O3 as the electrolyte indicates that Ni-Al a lloy, Ni-Al2O3 catalyst and Ni-YSZ cermet are potential candidates for anod e materials and that LiNiO2, LiCoO2, Ag-SnO2 and La0.8Sr0.2MnO3 are good ca ndidates for cathode materials. Among the tested electrode materials, for t he same electrolyte, the LiNiO2/Ni-Al2O3 electrode pair gives the best cell performance.
