Abstract

Fuel cell electrode where a metal structure in the form of a three-dimensional network is so arranged that it encloses a large number of cellular chambers which are interconnected. The structure is produced by depositing a metal onto a porous material, such as polyurethane foam, using an electrical coating technique to produce fuel cell electrodes of uniformly distributed porosity.
