ABSTRACT:
A novel plenum-free gas diffusion electrode assembly, and cells utilizing the same, embodying a catalyzed preferably carbon cloth or paper sheet contacting on one side a solid metal supporting current collector sheet, as with the aid of a conductive adhesive layer, and preferably though not always essentially carrying an electrolyte-permeable aqueous polymeric hydrogel coating on the other side, with the current collector sheet provided with gas (e.g., hydrogen, oxygen or air) inlet openings occupying a very minor portion of the surface of the current collector sheet.
