Abstract
A method of producing an electrode having a high performance in a simple and convenient manner which does not require the use of any of the medium, surfactant and pore-producing agent is disclosed. In the disclosed method, a layer including a catalyst powder is formed on a surface of a polymer electrolyte film or a porous conductive electrode substrate by supplying an electrostatically-charged catalyst powder to the polymer electrolyte film or the porous conductive electrode substrate. Alternatively, a layer including a catalyst powder is formed on a surface of a polymer electrolyte film or a porous conductive electrode substrate by spraying the catalyst powder on the surface of the polymer electrolyte film or the porous conductive electrode substrate together with a carrier gas, thereby to cause the catalyst powder to adhere to the surface.
