Abstract
Official abstract text for this publication.
Provided are an electrolyzer having excellent durability against reverse current. The electrolyzer 300 includes an anode 314, an anode chamber 310 housing the anode 314, a cathode 330, a cathode chamber 320 housing the cathode 330, and a diaphragm that separates the anode chamber 310 and the cathode chamber 320, wherein a reverse current absorption body 334 formed of a sintered compact containing nickel is disposed in at least one of an inside of the cathode chamber 320 and an inside of the anode chamber 310, and the reverse current absorption body 334 is not directly coupled to the cathode 330 and the anode 314 but is electrically connected to at least one of the cathode 330 and the anode 314.
First claim

1 . An electrolyzer comprising: an anode, an anode chamber housing the anode, a cathode, a cathode chamber housing the cathode, and a diaphragm that separates the anode chamber and the cathode chamber, wherein at least one reverse current absorption body formed of a sintered compact containing nickel is disposed in at least one of an inside of the cathode chamber and an inside of the anode chamber, and the at least one reverse current absorption body is not directly coupled to the cathode and the anode but is electrically connected to at least one of the cathode and the anode. 2 . The electrolyzer according to claim 1 , further comprising a cathode current collector disposed in the cathode chamber and opposed to the cathode, wherein the at least one reverse current absorption body is coupled to the cathode current collector. 3 . The electrolyzer according to claim 1 , further comprising an anode current collector disposed in the anode chamber and opposed to the anode, wherein the at least one reverse current absorption body is coupled to the anode current collector. 4 . The electrolyzer according to claim 1 , wherein the at least one reverse current absorption body is attached to at least one of a frame body defining the cathode chamber and a first support member disposed in the cathode chamber and supporting the cathode. 5 . The electrolyzer according to claim 1 , wherein the at least one reverse current absorption body is attached to at least one of a frame body defining the anode chamber and a second support member disposed in the anode chamber and supporting the anode. 6 . The electrolyzer according to claim 1 , wherein the content of nickel in the sintered compact containing nickel is 45 to 90 mass %. 7 . The electrolyzer according to claim 1 , wherein a density of the at least one reverse current absorption body is 2.00 to 6.51 g/cm 3 .
