Evaluation of novel solid electrolyte materials.

摘要

Solid-state fuel cells have the potential for becoming one of the most trouble-free fuel cell systems. The use of solid electrolyte virtually eliminates corrosion reactions and redistribution due to a liquid electrolyte. The project is structured to first focus on developing new candidate electrolyte materials. Once suitable electrolyte materials have been identified, compatible electrode and interconnect materials will be developed. Central to the theme of the project is to find an electrolyte that could function as the basis of all four cell components, depending on dopant. In this way, the stresses due to thermal mismatch could be much smaller than those in a cell made from different materials. Following this approach, two classes of compounds were chosen initially for evaluation: perovskites scheelites. 3 refs. (ERA citation 15:034598)
