Abstract
An electricity leading method for a gas diffusion electrode is provided, by which a gas diffusion electrode is easily fixed to a cathode current collecting frame, the contact part has reduced electrical resistance, even an electrically insulating mesh sheet can be utilized as a gas chamber, and only the gas diffusion electrode can be replaced in renewal of the electrode. The method includes preparing a gas diffusion electrode by sandwiching a conductor made of a highly conductive metallic mesh or spongy processed material in catalyst layers or attaching a catalyst layer onto the conductor while leaving the conductor exposed in the outer periphery of the electrode, and electrically connecting the exposed part of the conductor to a cathode chamber current collecting frame.
