Abstract (en)
[origin: WO0193353A1] The invention relates to a dimensionally stable gas diffusion electrode and to a method for producing the same. The inventive electrode comprises at least one electroconducting catalyst substrate for receiving a coating mass that contains a catalyst material, and one electrical connection. The catalyst substrate (4; 11) may be a tissue, a nonwoven, a foam, a sintered metal body or felt from a electroconducting material, an expanded metal plate or a metal plate that is provided with a multitude of openings (2, 8), on which the coating material (5) that contains the catalyst material is applied. The catalyst substrate, if not sufficiently rigid itself, is firmly linked with a gas-permeable, alkali-resistant metal base plate (1; 7), especially produced from nickel or one of its alloys in a mechanical and electroconducting manner.
