Title:
ELECTROCHEMICAL CELL FOR HYDROGEN PUMPS, AND COMPRESSION APPARATUS
Document Type and Number:
WIPO Patent Application WO/2022/249560
Kind Code:
A1
Abstract:
An electrochemical cell for hydrogen pumps is provided with an electrolyte membrane (11), an anode catalyst layer (13) provided on one main surface of the electrolyte membrane, a cathode catalyst layer (12) provided on the other main surface of the electrolyte membrane, an anode gas diffusion layer (15) provided on the anode catalyst layer (13), and a cathode gas diffusion layer (14) provided on the cathode catalyst layer (12), in which the cathode gas diffusion layer (14) is exposed to a hydrogen-containing gas having a higher pressure than the pressure in the anode gas diffusion layer (15) and the thickness (T) of the anode gas diffusion layer (15) is equal to or larger than the thickness (t) of the cathode gas diffusion layer (14) during the application of a voltage between the anode catalyst layer (13) and the cathode catalyst layer (12).
