Title:
ELECTROCHEMICAL HYDROGEN PUMP
Document Type and Number:
WIPO Patent Application WO/2023/037755
Kind Code:
A1
Abstract:
Provided is an electrochemical hydrogen pump provided with an electrolyte membrane, an anode provided on one of the main surfaces of the electrolyte membrane, a cathode provided on the other of the main surfaces of the electrolyte membrane, and an anode separator provided on the anode, a cathode separator provided on the cathode, and a voltage application device for applying a voltage between the anode and the cathode. The electrochemical hydrogen pump is an apparatus configured such that hydrogen in a hydrogen-containing gas supplied to the anode is transferred to the cathode through the electrolyte membrane by applying the voltage by means of the voltage application device, thereby generating compressed hydrogen. The anode includes an anode catalyst layer and an anode gas diffusion layer, in which, in the anode gas diffusion layer, the surface roughness of the anode-separator-side main surface is larger than the surface roughness of the anode-catalyst-layer-side main surface.
