ABSTRACT:
A method for making a fuel cell electrode is disclosed. A layer of hydrophobic polymer and an electro-catalyst is deposited on the surface of a porous electrode substrate and press-sintered by heating the catalyst layer to a temperature between the melting point and decomposition temperature of the polymer and simultaneously compressing the layer at a pressure between 20 pounds per square inch and 100 pounds per square inch. The heating and compressing are continued for a time period of between 10 minutes and 20 minutes. A fuel cell electrode made by the above method and a method for generating electricity using such an electrode are also disclosed. A press-sintered fuel cell electrode provides improved peak performance as well as improved tolerance to electrolyte solidification.
