Alkaline Membranes Based on Poly(vinylalcohol) for PEM Fuel Cells

摘要

Several samples of polyvinyl alcohol (PVA) based anion exchange membranes were prepared by different ways. Membrane electrode assembly (MEA) structures with platinum electrodes were produced and their loading and power characteristics were measured. The best PVA membrane was also used for MEA structure with MnO_x based positive electrode. The measured data were compared with a reference Nafion 115 membrane fuel cell.
