ABSTRACT:
A gas diffusion electrode is provided with antipercolation coating by bonding a free-standing film, e.g. of polysulfone or polypropylene, to a catalyzed carbon cloth utilizing a filled polysulfone/N-MP adhesive which is subjected to solvent exchange with water by either a thermal bonding as in the case of a free-standing microporous polysulfone film or mechanical bonding as in the case of a commercial microporous polypropylene film.
