Paper Abstract

The solid polymer fuel cell (SPFC) technology is one of the most promising sources of future energy. Its high power density and mild operating conditions make the SPFC technology highly attractive for stationary, portable, and automobile applications. In this paper, we briefly discuss the potential use of electro-active polymer materials for the SPFC technology. In order to realize the fast intrinsic kinetics of the cathode reaction an efficient utilization of the Pt catalyst is necessary. In this sense, we introduce a novel concept of a fabrication technique of the membrane-electrode assembly (MEA) that consists of a Pt-deposited ion exchange membrane and two current collectors. It appears that the manufacturing process of such MEAs is simple, efficient, and economical relative to the current state-of-art MEA technology that employs various particle distribution techniques. Also, it should be pointed out that the use of this new MEA fabrication technique could improve the rate density of H+ transport significantly.
