Cathode catalyst is a dominant parameter hindering the development of proton exchange membrane fuel cells (PEMFCs), exploiting non-precious metal based catalysts with low cost and high activity has become an urgent task in recent decades. In this work, a non-precious metal based catalyst of heat-treated nitrogen doped carbon supported transition metal based catalyst (M-N/C catalyst) was chosen as the subject, and a series of Fe-PPy-TsOH/C catalysts were synthesized with iron salt as the metal precursor, BP 2000 carbon black as the carbon source, polypyrrole (PPy) as the nitrogen source, and methyl benzene sulfonic acid (TsOH) as the dopant. The effects of heat-treatment temperature and cobalt-doping on the phase structure, morphologyand catalytic performance towards oxygen reduction reaction (ORR) were comparatively investigated. It shows that 800℃ is the optimal heat-treatment temperature to prepare high performance Fe-PPy-TsOH/C catalyst. If the iron in the Fe-PPy-TsOH/C catalyst is replaced by appropriate amount of cobalt, its catalytic performance towards ORR could be further improved, and the best ORR performance could be achieved at a cobalt cotent of 33.33% (Fe:Co=2:1 in ratio) in the range of 0-50at%.
