Abstract

Assembling fuel cell electrodes between support frames 0-5-1.5 mm thick of a resilient material pref. neoprene (polychloroprene) rubber secured to the adjacent (sintered Ni) electrodes by a suitable adhesive (neoprene-based). The rubber frames are porous but the seal zones are clamped under a pressure of 1-3 tonnes/cm2 to inhibit diffusion at the edges. The rubber frames incorporate (polyamide) or textile reinforcement to prevent extrusion of the rubber from between the electrodes under high clamping pressures. To replace the usual stack of rubber and porous metal gasket assemblies.
