hybrid membrane, low temperature, PEMFCs, conductivity
Organic-inorganic hybrid proton-conducting materials are expected to be the next generation, of high-performance membranes in a variety of fields as they have both the functionality of organic compounds and the stability of inorganic substances. The use of such materials should reduce the cost of fuel cells. The proton exchange membrane fuel cell based on a hybrid nanocomposite electrolyte material that exhibits high protonic conductivity at elevated temperatures. Phosphosilicate with heteropolyacids nanocomposite system was selected for the fuel cell evaluation in this study. The objective of the present work was to develop a new less expensive nanocomposite membrane with high proton conductivities for low-temperature fuel cells.
