Electrolysis device

Abstract

The present invention provides an electrolyzing apparatus that includes a detector configured to detect an abnormality in a electrolytic bath and thereby enables a quick detection of the occurrence of the abnormality and that is less prone to a malfunction in which, due to an environmental change, a normal state is misjudged as abnormal and electrolysis is stopped. An electrolyzing apparatus of the present invention includes an electrolyzing section and a detecting section, the electrolyzing section being configured to receive an electrolytic substance, electrolyze the electrolytic substance to obtain an electrolysis product, and discharge the electrolysis product. The electrolyzing section includes electrolysis electrodes. The detecting section includes a detection electrode configured to measure an electrical property of either one of or a mixture of both of the electrolytic substance and the electrolysis product and is configured to detect a decrease in amount of the electrolytic substance supplied to the electrolyzing section or a decrease in amount of the electrolysis product discharged from the electrolyzing section.
