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 โข C. The composite membranes were prepared by the recasting procedure, using Nafion solution mixed with

It has been reported that a thin polybenzimidazole (PBI)/poly(tetrafluoro ethylene) (PTFE) composite membrane (thickness 25-30 m) can be prepared by impregnating a thin porous PTFE (thickness 15-20 m) in a PBI/N,N -dimethyl actamide (DMAc) solution. In this paper, a 400 h life test of a fuel cell pr
