Abstract: In a state where battery cells (2) are sandwiched from both ends by a pair of end plates (3) comprising a plurality of plates, the pair of end plates (3) are secured by metal bands (4). The end plates (3) are secured by bolts to a base, at the inside end of the plates as seen from the battery cells (2). Then, elongation of the assembled battery (1) can be kept to a small range, even when the battery cells (2) are swollen.

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.
