  "textContent": "An electrochemical hydrogen pump includes an electrolyte membrane, an anode catalyst layer on one primary surface of the electrolyte membrane, a cathode catalyst layer on the other primary surface of the electrolyte membrane, an anode gas diffusion layer on the anode catalyst layer, an anode separator on the anode gas diffusion layer, and a voltage applicator that applies a voltage between the anode catalyst layer and the cathode catalyst layer. Application of the voltage causes hydrogen in a hydrogen-containing gas supplied to above the anode catalyst layer to move above the cathode catalyst layer and to be pressurized. The anode gas diffusion layer includes a porous carbon sheet that contains carbon fibers and a carbon material different from the carbon fibers and that has a larger porosity in a first surface layer on the anode separator side, than in a second surface layer on the anode catalyst layer side.",
