Recent research work on the polymer electrolyte fuel cell (PEFC) is described. This research work addresses the goal of bringing the PEFC technology to the performance and the cost levels required for its wide spread use in transportation. The main topics are (a) a new approach to the fabrication of Pt/C catalyst layers of high performance, employing loadings as low as 0.1 mgPt/cm²; (b) measurements and modeling of membrane, cathode catalyst and cathode backing contributions to cell loses in the PEFC; and (c) carbon monoxide poisoning of anode electrocatalysts in the PEFC -- the problem and possible solutions. 13 refs.
