Title: Fuel cell electrode and method of preparation

Abstract

A fuel cell having good resistance to compressive creep includes electrodes having a superstructure of porous electrically conductive foam with surface sections adjacent to opposing surfaces of an electrolyte matrix impregnated with electrode catalyst materials. The catalyst materials are affixed in sections contiguous to an inner major surface by sinter bonding, electrochemical bonding or restrictive interstitial spacing. The outer sections of the porous plaque thickness are reserved for gas distribution to the electrode catalyst. Oxidant and fuel gases can be separately manifolded into alternate sides of a fuel cell stack by sealing opposing edges of the porous plaques containing the anode material in one set of opposing side surfaces and sealing opposing edges of the porous plaque containing cathode material in alternate side surfaces of the stack.
