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.
