ELECTROLYZER, ELECTRODES USED THEREFOR, AND ELECTROLYSIS METHOD

摘要

An electrolyzer comprises an anode and a cathode which are in touch with an electrolytic solution, and at least one of the anode and the cathode is composed of an electric conductor with a gas permeable structure comprising a gas producing surface at which gas is produced by electrolysis of the electrolytic solution, many through-holes leading from the gas producing surface to a different surface and allowing the gas produced at the gas producing surface to selectively pass therethrough, and a gas releasing surface which is the different surface for releasing the gas supplied from the gas producing surface via the through-holes. At least one of a surface treatment which causes the gas producing surface to be lyophilic for the electrolytic solution and a surface treatment which causes the gas releasing surface to be lyophobic for the electrolytic solution is performed.
