ABSTRACT:
Disclosed herein is a gas diffusion electrode comprising a reaction layer and a gas diffusion layer attached to each other characterized in that a plurality of apertures or a concave convex surface is provided on or through the electrode to facilitate the flowing of an electrolyte. In this electrode, a large volume of an electrolyte and a gas can flow even though the interelectrode distance is small so that a reaction can be promoted to elevate the efficiency.
