Oxygen-consuming electrode and method for its production

An oxygen consumption electrode comprises a current collector and a gas diffusion layer with a catalytic active component. The gas diffusion layer has a fluorinated polymer porous film, preferably a porous polytetrafluoroethylene film in which fine catalyst particles having average diameter of 0.05-5 mu m and average length of 10-700 mu m as catalyst active component is introduced. The gas diffusion layer is electrically connected with current collector. Independent claims are included for the following: (1) electrolysis device; and (2) manufacture of oxygen consumption electrode.
