Title:
ELECTROLYSIS APPARATUS AND ELECTROLYSIS METHOD
Document Type and Number:
WIPO Patent Application WO/2017/030153
Kind Code:
A1
Abstract:
Provided are an electrolysis apparatus and an electrolysis method capable, in an electrolytic process for generating hydrogen, of reliably eliminating the danger of trace amounts of gas gradually accumulating in an electrolytic solution circulation line and reaching the hydrogen explosion limit. The electrolysis apparatus 1 is characterized in that a gas phase region 21, in which hydrogen gas can exist in a gas phase, is provided with a positive electrode gas-feeding line 20, which is for feeding positive electrode gas to dilute the hydrogen gas concentration and which connects the gas phase region 21 with a positive electrode-side gas-liquid separation means. The electrolysis apparatus and electrolysis method dilute the hydrogen gas concentration in the gas phase region 21 with the positive electrode gas and reliably keep the hydrogen gas concentration below the lower explosion limit as a result of the positive electrode gas-feeding line 20 feeding at least a portion of the positive electrode gas to the gas phase region 21.
