ABSTRACT:
A gas diffusion electrode is constituted by forming a porous layer comprising a super-fine particle catalyst of silver or gold and a fluorine-containing material on a substrate and connecting a gas-liquid permeable collector to the substrate.
The gas diffusion electrode can be used stably as an oxygen cathode for a sodium chloride electrolysis, etc., for a long period of time without causing decreased water repellency of the fluorine-containing material in the gas diffusion electrode and without lowering the activity of the electrode substance.
