ABSTRACT:
An electrolytic solution prepared by dissolving an electrolyte such as KOH in pure water is fed into a membrane electrolytic cell of a membrane electrolyzer membrane electrolysis, made while the membrane electrolytic cell is provided intermittently or continuously with pure water. Oxygen generated at the anode and hydrogen generated at the cathode are purified individually by purifiers to produce oxygen and hydrogen of high purity. Also disclosed are methods of producing oxygen and hydrogen of high purity and their corresponding apparatuses in which a membrane degassing module is employed in conjunction with a solid polymer electrolyte electrolytic cell for effecting membrane electrolysis of the pure water, and in conjunction with a molecular sieve for individually dehumidifying oxygen generated at the anode and hydrogen at the cathode of the electrolytic cell.
