METAL-POLYMER COMPOSITE CATALYSTS AND METHOD OF MAKING

摘要

A metal-polymer-carbon composite catalyst for use as a cathode electrocatalyst in fuel cells. The catalyst includes a heteroatomic polymer; a transition metal linked to the heteroatomic polymer by one of nitrogen, sulfur, and phosphorus, and a recast ionomer dispersed throughout the heteroatomic polymer- carbon composite. A membrane electrode assembly for fuel cells and methods of making the metal-heteroatomic polymer-carbon composite catalyst and the membrane electrode assembly are also described.
