Title:
ELECTROCHEMICAL HYDROGEN PUMP
Document Type and Number:
WIPO Patent Application WO/2020/250508
Kind Code:
A1
Abstract:
This electrochemical hydrogen pump comprises an electrolyte membrane provided with a pair of main surfaces, a cathode catalyst layer provided to one main surface of the electrolyte membrane, an anode catalyst layer provided to the other main surface of the electrolyte membrane, and a voltage applicator that applies a voltage between the cathode catalyst layer and the anode catalyst layer, the electrochemical hydrogen pump being such that, due to application of the voltage by the voltage applicator, hydrogen in a hydrogen-containing gas supplied to the anode catalyst layer is caused to move to the cathode catalyst layer and is pressurized. Before a user begins initial use of the electrochemical hydrogen pump, the anode catalyst layer has greater unevenness in cross-sectional shape than does the cathode catalyst layer.
