摘要： A compression apparatus includes at least one compression unit including an electrolyte membrane, an anode provided on a first principal surface of the electrolyte membrane, a cathode provided on a second principal surface of the electrolyte membrane, an anode separator stacked on the anode, and a cathode separator stacked on the cathode, a voltage applier that applies a voltage between the anode and the cathode, an anode end plate provided on the anode separator located at a first end in a direction of stacking, a cathode end plate provided on the cathode separator located at a second end in the direction of stacking, and a plate-like member provided between the cathode end plate and the cathode separator located at the second end or between the anode end plate and the anode separator located at the first end. The compression apparatus causes, by using the voltage applier to apply a voltage, protons taken out from an anode fluid that is supplied to the anode to move to the cathode via the electrolyte membrane and generates compressed hydrogen. The plate-like member is provided with a recess in which to store the compressed hydrogen and a groove portion that surrounds an outer periphery of the recess. The groove portion is provided with a seal material and a ring material that is adjacent to an outer edge of the seal material and that surrounds the seal material. An outer peripheral surface of the groove portion and an outer peripheral surface of the ring material are both provided with gradients so as to become wider toward an opening of the groove portion.

摘要： A compression device includes: an electrochemical cell that includes an anode and a cathode that sandwich an electrolyte membrane; a voltage application unit that applies a voltage between the anode and the cathode; and a metal plate that is exposed to compressed hydrogen generated at the cathode and that is resistant to hydrogen embrittlement. The metal plate includes a first terminal connected to the voltage application unit. The first terminal is directly connected to a second terminal that has a lower resistance than the first terminal. The second terminal is directly connected to the voltage application unit, and the first terminal is connected to the voltage application unit via the second terminal.

摘要： A compression apparatus includes a stack including a plurality of electrochemical cells stacked on top of one another, the electrochemical cells each including an anode, a cathode, and an electrolyte membrane interposed between the anode and the cathode, a pair of insulating plates disposed at respective ends of the stack in a direction in which the electrochemical cells are stacked, a pair of end plates disposed on outside surfaces of the respective insulating plates, and a voltage applicator that applies a voltage between the anode and the cathode. Upon the voltage applicator applying the voltage, the compression apparatus causes protons extracted from an anode fluid fed to the anode to move to the cathode and produces compressed hydrogen. At least one of the end plates has a cathode gas channel formed therein, the cathode gas channel through which a cathode gas including the compressed hydrogen flows. The end plate having the cathode gas channel includes a first region including an outer peripheral surface of the cathode gas channel, the first region being composed of a first steel material, and a second region other than the first region, the second region being composed of a second steel material. The first steel material has higher hydrogen embrittlement resistance than the second steel material, and the second steel material has higher stiffness than the first steel material.
