## Abstract High temperature proton exchange membrane fuel cells (HTβPEMFCs) with phosphoric acid doped polybenzimidazole (PBI) membranes have gained tremendous attentions due to its attractive advantages over conventional PEMFCs such as faster electrochemical kinetics, simpler water management, hi

Nafion/silicon oxide (SiO 2 )/phosphotungstic acid (PWA) and Nafion/silicon oxide composite membranes were studied for the H 2 /O 2 proton exchange membrane fuel cells (PEMFCs) operated above 100 β’ C. The composite membranes were prepared by the recasting procedure, using Nafion solution mixed with
The effect of chloride as an air impurity and as a catalyst contaminant on the performance and durability of polybenzimidazole (PBI)-based high temperature proton exchange membrane fuel cell (HT-PEMFC) was studied. The ion chromatographic analysis reveals the existence of chloride contaminations in
