## Abstract This study focuses on the performances of proton exchange membrane fuel cells (PEMFCs) at 80 and 90βΒ°C with feeds of varying degrees of humidification. The results show that ohmic resistance of the solid electrolyte decreases as the current density is raised because of the back diffusio

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
The electrochemical characteristics of a platinum electrode directly bonded to one side of a solid polymer electrolyte membrane (PtGSPE) were studied. Current-potential relations of hydrogen and oxygen adsorbed on F't SPEwere observed to be similar IO those on a platinum metal electrode, independent
## Abstract A new membrane material has been developed, based on a polysiloxane framework with functional proton conducting groups such as sulfonic acid and heterocyclic groups, e.g., imidazole and benzimidazole, covalently bonded at the siloxane backbone. Sulfonated siloxane based blockβcopolymers
