Abstract:High‐temperature proton exchange membrane fuel cell (HT‐PEMFC) based on phosphoric acid doped polybenzimidazole membrane (PBI/PA) operating at 120–200 °C can provide insensitivity to carbon monoxide (CO) and simplified managements of water and heat and thus attract significant global attention. However, one significant drawback is its low utilization of precious metal catalysts resulted from the PA poisoning and inefficient three‐phase boundary. Studies of binder materials in catalyst layers for HT‐PEMFC are g… Show more
