  "textContent": "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.",
