Thermal curing of PBI membranes for high temperature PEM fuel cells

Three-Dimensional Modeling and Experimental Study of a High Temperature PBI-Based PEM Fuel Cell

This paper investigates the performance of a high temperature proton exchange membrane PEM fuel cell. Both experimental work and numerical simulation are conducted. The high temperature proton exchange membrane is based on polybenzimidazole PBI doped with phosphoric acid. A single cell with triple serpentine flow channels was operated at steady state at various levels of temperature, pressure, ...

Combinatorial Study of Blended Membranes for PEM Fuel Cells

Among fuel cell technologies, polymer electrolyte membrane fuel cells (PEMFCs) have gained momentum at a strong pace in small to medium scale energy generation (e.g., mobile applications, transportation, etc). Historically, the development of polymer electrolytes has gone through several stages: from ionic polymers of poly(ethylene oxide)-salt complexes, polystyrene sulfonate polymers, to perfl...
