Method of producing gas diffusion electrode

摘要

A method of producing a gas diffusion electrode by forming a thin layer comprising a carbon power and a silver powder on the surface of a substrate comprising silver, copper, nickel or stainless steel and fluorinating the thin layer make the carbon water repellent. The gas diffusion electrode can be stably used for a long period of time in sodium chloride electrolysis, etc., without clogging the passage of gas and lowering the water repellency of the electrode.
