Abstract:

High temperature polymer electrolyte membrane fuel cells(HT-PEMFCs) are one form of energy conversion device which have many advantages compared with traditional low temperature PEMFCs. The catalysts in HT-PEMFCs are mainly Pt-based catalysts which have good catalytic activity to the oxygen reduction reaction(ORR) and hydrogen oxidation reaction(HOR). A high loading amount of Pt is used to alleviate the negative effect on activity expression caused by strong absorption of PA on the Pt surface. And Pt catalysts suffer from the issue of inadequate activity, activity loss during long term operation, high cost and support corrosion under harsh conditions. In this review, we summarize recent studies about catalysts in HT-PEMFCs and systematically analyze the further appli- cation of precious and non-precious metal catalysts. Furthermore, we give our perspectives about the problems that the catalysts in HT-PEMFCs currently have.

Key words: High temperature polymer electrolyte membrane fuel cell, Pt-based catalyst, Oxygen reduction reaction, Hydrogen oxidation reaction
