Title:
REVERSIBLE WATER ELECTROLYSIS SYSTEM AND OPERATION METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2020/180082
Kind Code:
A1
Abstract:
The present invention relates to a reversible water electrolysis system and an operation method thereof, the reversible water electrolysis system comprising: a reversible water electrolysis fuel cell; a first discharge path; a second discharge path; a catalyst combustor; and an air-exhaust gas heat exchanger. . The reversible water electrolysis fuel cell comprises a hydrogen electrode, an air electrode, and an electrolyte interposed between the hydrogen electrode and the air electrode, and can operate in one mode from among a water electrolysis mode and a fuel cell mode. The first discharge path transports first discharge gas discharged from the hydrogen electrode. The second discharge path transports second discharge gas discharged from the air electrode. The catalyst combustor is supplied with part of the first discharge gas so as to heat the second discharge gas. The air-exhaust gas heat exchanger is installed at a downstream side of the catalyst combustor and exchanges heat between air that is supplied to the air electrode and the second discharge gas.
