Abstract
An electrochemical hydrogen pump includes: an electrolyte membrane; a cathode catalyst layer provided on one principal surface of the electrolyte membrane; an anode catalyst layer provided on the other principal surface of the electrolyte membrane; a pair of separators which include gas flow paths and which are provided so as to sandwich the cathode catalyst layer and the anode catalyst layer; and a voltage application portion applying a voltage between the cathode catalyst layer and the anode catalyst layer. In the electrochemical hydrogen pump, the one principal surface is disposed at an upper side in the gravity direction, and the cathode catalyst layer has a hydrophilic property.
