Abstract
Novel nanocatalyzed membrane electrode assembly (MEA) with high performance and durability for polymer electrolyte membrane fuel cell application is prepared by modifying nonequilibrium impregnation–reduction method. The electrochemical and physical properties of nanocatalyzed MEA have been examined using various techniques such as cyclic voltammetry, impedance spectroscopy, scanning electron microscopy, and X-ray diffraction studies. The lifetime of the nanocatalyzed MEA is studied and compared with that of the conventional one. It is observed that the performance and durability of nanocatalyzed MEA are better than the conventional one. In addition, the influence of supported carbon corrosion in MEA durability has been studied.
