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.

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.

Cathode gas flow channels in which the cathode gas flows are connected to each other. The amount of thickness reduction of the cathode gas diffusion layer due to compression resulting from fastening of the fastener is larger in the hydrogen pump unit positioned at at least one end of the stacked hydrogen pump units than in the hydrogen pump unit positioned at neither end of the stacked hydrogen pump units.
