Abstract: Disclosed herein is a gas permeable electrode which comprises a gas permeable layer and a reaction layer, the reaction layer comprising hydrophobic portions and hydrophilic portions. Electrolyte penetrates into the reaction layer and does not penetrate into the gas permeable layer, and only the gas produced on the electrode and the gas supplied penetrate into the gas permeable layer. The gas can be released from the rear side of the electrode and the reaction surface thereof is never covered with the gas.

Abstract: A method for producing a highly dispersed catalyst comprising mixing a cross linking agent with a polymer in a solvent to cross-link the polymer, applying the cross-linked mixed liquid to a carrier, drying the carrier to remove the solvent and to form a polymer film over the surface of the carrier, impregnating the polymer film with a metallic complex compound solution to connect the complex compound to a reactive functional group of the polymer film, and reducing the complex compound of the polymer film, thereby obtaining the highly dispersed catalyst having superior catalytic properties and superior catalytic efficiency.
