Abstract

The electrode comprises an electronically conducting core, a current collector, a layer of active material surrounding the core and consisting of an agglomerate of 10-70 wt.% catalyst grains and binder particles, and a porous barrier layer assuring the diffusion of electrolyte towards the active layer as well as ionic counter-diffusion of the reaction prods. The binder comprises 30-80 wt.% hydrophobic material (pref. PTFE of polymsn. degree >=10) and 10-40 wt.% org. medium (pref. acrylonitrile-butadiene latex).
