质子导体基固体氧化物燃料电池的新认识

Proton-conducting solid oxide fuel cells (P-SOFCs/PCFCs) are all-solid-state, eco-friendly, and economic power generation devices for proton conduction in oxide lattices. This review represented the proton conduction mechanism, the typical electrolyte and electrode materials used in PCFCs, and the efficient construction of the internal proton conduction pathways based on the development of low-temperature working SOFCs. The principles of designing these materials were analyzed and some possible problems in this aspect were discussed. This review also indicated the future work on PCFCs to develop some novel electrolytes and electrode materials with an improved proton conductivity.
