Document Type and Number:
Japanese Patent JP3002993
Kind Code:
B1
Abstract:
PROBLEM TO BE SOLVED: To provide a gas diffusion electrode with a metallic frame or a gas chamber capable of constituting an electrolytic cell of brine which may be easily replaced with a conventional hydrogen generating cathode and extremely hardly gives rise to the occurrence of liquid leakage and gas leakage and an electrolytic cell of brine using the same. SOLUTION: This gas diffusion electrode with the metallic frame is constituted by joining the gas diffusion electrodes 1 via silver plates to the apertures of the corrosion resistant metallic frames 15 having the apertures 16 at 2 >=points. The gas diffusion electrode with gas chambers is constituted by joining the gas diffusion electrode with the metallic frame and an electrode pan composed of a nickel plate to constitute a gas chamber and attaching an inlet and outlet for gas thereto. The electrolytic cell of brine is constituted by disposing the gas inlet and outlet from the outside of the electrolytic cell to the gas diffusion electrode with the gas chamber and directly joining the metallic joint part of the electrode to the power feeding rib of the electrolytic cell and/or the electrolytic cell frame.
