METHOD FOR PRODUCING A GAS DIFFUSION ELECTRODE

摘要

The invention relates to a method for producing a gas diffusion electrode, especially for the electrolysis of an aqueous solution of hydrogen chloride. In a first step a) a dispersion of a catalyst containing noble metal and an ionomer conducting a proton in an organic solvent is sprayed onto an electrically conductive carrier. Said conductive carrier is optionally provided with a coating material containing an acetylene black-polytetrafluoroethylene mixture. In a second step, b) the organic solvent is removed.
