摘要: Pt4ZrO2/C was prepared and compared with commercial Pt/C (46.6 wt.% TKK) in terms of the durability as cathode catalyst in a high temperature proton exchange membrane fuel cell (PEMFC) based on H3PO4 doped polybenzimidazole (PBI) by a potential sweep test. The catalysts before and after the potential sweep test were characterized by RDE, XRD, TEM and ICP-AES. After 3000 cycles potential sweep test, the overall performance loss of the Pt4ZrO2/C membrane electrode assembly (MEA) was less than that of the Pt/C MEA. In brief, the preliminary results indicate that Pt4ZrO2/C catalyst is a good candidate of Pt/C catalyst in high temperature PEMFC based on H3PO4 doped PBI for achieving longer cell life-time and higher cell performance.
