Title:
COMPRESSION APPARATUS
Document Type and Number:
WIPO Patent Application WO/2021/106482
Kind Code:
A1
Abstract:
This compression apparatus comprises: an electrolyte membrane; an anode catalyst layer in contact with one main surface of the electrolyte membrane; a cathode catalyst layer in contact with the other main surface of the electrolyte membrane; an anode diffusion layer provided on the anode catalyst layer and including a carbon porous sheet; a cathode gas diffusion layer provided on the cathode catalyst layer; an anode support provided on the anode gas diffusion layer and including a metal sheet having a plurality of air vents; an anode separator provided on the anode support and including a fluid flow path through which an anode fluid flows on the main surface on the anode support side; and a voltage application device that applies a voltage between the anode catalyst layer and the cathode catalyst layer. As the voltage application device applies the voltage, the compression apparatus causes protons extracted from the anode fluid supplied to the anode catalyst layer to move to the cathode catalyst layer via the electrolyte membrane, thereby generating compressed hydrogen. The bending strength of the metal sheet is higher than the bending strength of the carbon porous sheet.
