Abstract
An electrode substrate is described which is suitable for supporting noble metal electrodes in fuel cells and similar electrochemical cells. It is composed of fine graphite particles enmeshed in a web of fibers of polytetrafluoroethylene (PTFE) produced by forming a homogeneous mixture of graphite particles and PTFE powder in an organic liquid, removing the liquid, and milling the mixture in a series of steps to form a thin, porous, electrically conductive sheet of graphite-PTFE which is an excellent support for thin film metallic electrodes and which is resistant to corrosive electrolytes.
