Abstract

Gas diffusion electrode for a battery cell comprises a mixt. of a conductive metal powder or carbon and a polyhaloethylene. The electrode is made by moulding the mixt. the heat treating the body produced at or above the melting point of the polyhaloethylene. The body is rigid and sound electrical contact can be made to a current collector. The electrode does not have to be made waterproof as in prior art.
