Title:
水の電気分解によって高純度水素及び／又は酸素を調製するための装置及び方法
Document Type and Number:
Japanese Patent JP7394226
Kind Code:
B2
Abstract:
Involved is a device for preparing high-purity hydrogen and/or oxygen by electrolyzing water, comprising an electrolyzer and a degasser for degassing desalted water. The degasser is located at the upstream of the electrolyzer. After desalted water is heated and degassed in the degasser, the content of gaseous impurities, particularly argon, can be reduced to several ppb (weight ratio). The hydrogen and oxygen generated after the desalted and degassed water is electrolyzed in the electrolyzer also contain an extremely small amount of argon, so that the requirements in semiconductor industry are met. Also involved is a method for preparing high-purity hydrogen and/or oxygen by using the device.
