Electrochemical hydrogen pump

An electrochemical hydrogen pump comprising:

• an anode end plate;
• a cathode end plate;
• at least one hydrogen pump unit that is disposed between the anode end plate and the cathode end plate in a stacking direction and includes an electrolyte membrane, an anode disposed on a first main surface of the electrolyte membrane, a cathode disposed on a second main surface of the electrolyte membrane, an anode separator stacked on the anode, and a cathode separator stacked on the cathode;
• an anode plate member disposed between the anode end plate and the at least one hydrogen pump unit and including an anode insulating plate in contact with the anode end plate and an anode power supply plate;
• a fixing member that prevents at least the anode end plate, the at least one hydrogen pump unit, the anode plate member and the cathode end plate from moving in the stacking direction;
• a space formed by the anode end plate and the anode plate member;
• a gas flow channel through which hydrogen generated in the cathode is supplied to the space disposed between the anode end plate and the anode plate member;
• and
• a pressure transmitting member that is disposed in the space and transmits a pressure from the at least one hydrogen pump unit to the anode end plate,
• wherein the pressure transmitting member includes a columnar member separately provided from or integrated with the anode end plate, and
• the columnar member contacts the anode power supply plate.
