摘要： A compression apparatus of the present disclosure includes an electrolyte membrane; an anode catalyst layer in contact with one of main surfaces of the electrolyte membrane; a cathode catalyst layer in contact with the other of the main surfaces of the electrolyte membrane; an anode gas diffusion layer in contact with the anode catalyst layer; a cathode gas diffusion layer in contact with the cathode catalyst layer; a cathode separator that is provided on the cathode gas diffusion layer; and a voltage applicator that applies voltage between the anode catalyst layer and the cathode catalyst layer. The compression apparatus generates compressed hydrogen by applying the voltage with the voltage applicator to move protons, taken out of an anode fluid supplied to the anode catalyst layer, to the cathode catalyst layer via the electrolyte membrane. The cathode gas diffusion layer includes a porous carbon sheet and is configured such that a porosity of a first surface layer in a side of the cathode separator is lower than a porosity of a layer inward from the first surface layer.

摘要： A hydrogen system includes a compressor that causes, by applying a voltage across an anode and a cathode with an interposed electrolyte membrane therebetween, hydrogen in a hydrogen-containing gas supplied to the anode to move to the cathode and produces compressed hydrogen; a pressure regulator that regulates pressure at least at the anode; and a controller that controls the pressure regulator to make the pressure at the anode higher than pressure at the cathode with the hydrogen-containing gas prevented from flowing out of the anode in a stop.

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： An electrochemical hydrogen pump includes an electrolyte membrane, an anode catalyst layer on one primary surface of the electrolyte membrane, a cathode catalyst layer on the other primary surface of the electrolyte membrane, an anode gas diffusion layer on the anode catalyst layer, an anode separator on the anode gas diffusion layer, and a voltage applicator that applies a voltage between the anode catalyst layer and the cathode catalyst layer. Application of the voltage by the voltage applicator causes hydrogen in a hydrogen-containing gas supplied to above the anode catalyst layer to move above the cathode catalyst layer and to be pressurized. The anode gas diffusion layer includes a porous carbon sheet that contains carbon fibers and a carbon material different from the carbon fibers and that has a larger porosity in a first surface layer, which is on the anode separator side, than in a second surface layer, which is on the anode catalyst layer side.

摘要： An electrochemical hydrogen pump includes an electrolyte membrane, an anode catalyst layer, a cathode catalyst layer, an anode gas diffusion layer, a cathode gas diffusion layer, an anode separator, a cathode separator, a first end plate and a second end plate that are disposed on the respective ends of at least one hydrogen pump unit in which the electrolyte membrane, the catalyst layers, the gas diffusion layers, and the separators are stacked on each other, a fastener that fastens the end plates and at least one hydrogen pump unit, and a voltage applier. The electrochemical hydrogen pump transfers hydrogen from the anode catalyst layer to the cathode catalyst layer and pressurizes hydrogen when the voltage applier applies the voltage. The cathode gas diffusion layer includes a water-repellent carbon fiber layer in a main surface thereof that is on a side of the cathode catalyst layer, and is compressed by the fastener.

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.
