Abstract
This specification discloses a gas diffusion electrode for a battery, wherein a layer which is formed of a binding agent and substance such as graphite, nickel oxide, aluminum oxide or the like so as to represent no catalytic action with respect to a fuel is provided on the electrolyte side of a high-porosity sintered member of which the constituent is nickel, thereby preventing a decrease in the electrode potential due to the active fuel and in the utilization rate of such fuel, while at the same time restraining permeation of a gas supplied to the electrode into the electrolyte and leakage of such electrolyte into the gas.
