Abstract
The materials and processes for forming fuel cell electrodes can include substrates of codeposited materials including an electrically conductive material, such as graphite, a polymer film, such as a proton-exchange membrane, and a catalytic material, such as platinum. The material may be applied to a polymer film by combustion chemical vapor deposition (CCVD) to produce a layered membrane, or the polymer may be deposited simultaneously with the catalytic coating to produce a membrane wherein the layers are intermingled. Proton exchange membranes prepared by this method are useful in the manufacture of fuel cells.
