Abstract
An electrochemical hydrogen pump includes an electrolyte membrane, an anode catalyst layer, a cathode catalyst layer, an anode gas diffusion layer, a cathode gas diffusion layer, an anode separator, a cathode separator, a first end plate and a second end plate that are disposed on the respective ends of at least one hydrogen pump unit in which the electrolyte membrane, the catalyst layers, the gas diffusion layers, and the separators are stacked on each other, a fastener that fastens the end plates and at least one hydrogen pump unit, and a voltage applier. The electrochemical hydrogen pump transfers hydrogen from the anode catalyst layer to the cathode catalyst layer and pressurizes hydrogen when the voltage applier applies the voltage. The cathode gas diffusion layer includes a water-repellent carbon fiber layer in a main surface thereof that is on a side of the cathode catalyst layer, and is compressed by the fastener.
