Proton Exchange Composite Membrane Based on AB Polybenzimidazole and Caesium Dihydrogen Phosphate for HT-PEM Fuel Cells
Year: 2024
Type: article
Abstract: A new type of polybenzimidazole-based proton exchange composite membrane, poly(2,5-benzimidazole) (ABPBI)–CsH2PO4, was obtained. The possibility of application of the composite membrane in a hydrogen–air fuel cell operating at 160–250 °C was demonstrated. In the fuel cell tests, the maximum power density reached ~400 mW/cm2 at 250 °C. The resulting data along with high open circuit voltage (0.92–0.95 V) indicate high quality and low hydrogen crossover of the membrane.
