Abstract
Methods of making fuel cell electrodes in which the pores of an electrically conductive metal substrate are filled with a slurry containing particles of the same or a different electrically conductive metal. The liquid phase of the slurry is removed, leaving the particles of conductive material in the pores of the substrate; and the conductive metal(s) making up the substrate and the metal particles supplied from the slurry are converted to oxide.
