Abstract
An electroconductive porous substrate such as carbon fiber paper with an electroconductive polymer deposited on the carbon fibers of the paper is used as a wicking material or diffusion medium in a fuel cell. The polymer may be deposited from a solution of monomers by electrochemical polymerization.
