Abstract: An electrochemical hydrogen pump includes at least one hydrogen pump unit including an electrolyte membrane, an anode, a cathode, an anode separator, and a cathode separator; an anode end plate disposed on the anode separator positioned in a first end in a stacking direction; a cathode end plate disposed on the cathode separator positioned in a second end in the stacking direction; a fixing member that prevents members from the anode end plate to the anode separator positioned in the first end from moving in the stacking direction; a gas flow channel through which hydrogen generated in the cathode is supplied to a space disposed between the anode end plate and the anode separator positioned in the first end; and a pressure transmitting member that is disposed in the space and transmits a pressure from the anode separator positioned in the first end to the anode end plate.

Abstract: This invention provides an electrochemical hydrogen pump which allows reduction efficiency due to increase of contact resistances to be suppressed with a light-weight and compact structure. An electrochemical hydrogen pump (24) comprises: single battery cells (m1-m3) that each include an anode separator (7), an anode diffusion layer (5), an anode electrode layer (3), an electrolyte membrane (2), a cathode electrode layer (4), a cathode diffusion layer (6), and a cathode separator (8); and pressurization spaces that are provided in positions sandwiching the anode diffusion layer and the cathode diffusion layer therebetween. The pressurization spaces include an anode pressurization space (27) provided in an anode-side member and a cathode pressurization space (28) provided in a cathode-side member.
