摘要
The chemical stability of Li2SO4 on the operation condition of a H-2/O-2 fuel cell has been investigated in this work. Thermodynamic calculation indicates Li2SO4 can react with H-2 at high temperature. The H-2/O-2 fuel cell using Li2SO4-alpha-Al2O3 as electrolyte exhibits good performance, but the stability of performance is not good. XRD analysis indicates that Li2SO4 reacts with H-2 at high temperature. Therefore, the Li2SO4-based proton conductors are not suitable for electrolytes for H-2/O-2 fuel cells.
