    Abstract: A hydrogen system includes: a compressor that includes an anode, a cathode, and an electrolyte membrane interposed therebetween and generates compressed hydrogen by applying a voltage between the anode and the cathode to move protons extracted from anode fluid supplied to the anode to the cathode; a voltage applicator that applies the voltage between the anode and the cathode; a first flow passage through which a cathode off-gas containing the compressed hydrogen discharged from the cathode is supplied to the anode of the compressor; a first on-off valve disposed in the first flow passage; and a controller that causes the voltage applicator to apply the voltage with the first on-off valve opened during a period of time from startup of the hydrogen system until supply of the cathode off-gas to a hydrogen reservoir is started.

    Abstract: A compression apparatus includes a stack of electrochemical cells each including an anode, a cathode, and an electrolyte membrane interposed therebetween, a pair of insulating plates disposed at respective ends of the stack in a stacking direction, 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. The end plate having the cathode gas channel includes a first region that includes an outer peripheral surface of the cathode gas channel and is composed of a first steel material and a second region other than the first region which is 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.

    Abstract: A solid oxide fuel cell including unit cells, including: a pair of interconnectors for electrically connecting the unit cells; a membrane-electrode assembly including an electrolyte membrane and a pair of electrode layers disposed with the electrolyte membrane therebetween; a pair of current collectors disposed between the electrode layers and the interconnectors so as to be in contact with the pair of electrode layers and the pair of interconnectors, respectively, and electrically connecting the pair of electrode layers and the pair of interconnectors; and elastic bodies biasing at least one current collector of the pair of current collectors toward a corresponding electrode layer and made of austenitic stainless steel.
