Abstract:

Protonic ceramic membrane fuel cells have received great attentions because they provide an effective way to reduce the operating temperatures of solid oxide fuel cells. A brief overview of current development in protonic ceramic membrane fuel cells with high temperature proton-conducting electrolytes is given, which points out that the poor chemical stability of traditional electrolyte materials for the protonic ceramic membrane fuel cell is the main obstacle for their applications. The present development of high temperature proton conductors with high chemical stability as electrolyte materials for protonic ceramic membrane fuel cells is reviewed, as well as the influence of novel element doping strategies on the chemical stability, ionic conductivity and sinterability for BaCeO3-based materials. It also indicates the problems of high temperature proton conductors for protonic ceramic membrane fuel cells as well as their prospects.
