    Abstract: A cell including: a pair of interconnectors for electrically connecting unit cells; a membrane-electrode assembly disposed between the interconnectors; a pair of current collectors, each of which includes an abutting surface abutting against a corresponding one of the electrode layers and a first base material surface being in contact with a corresponding one of the interconnectors and electrically connecting the corresponding of the electrode layers and the corresponding one of the interconnectors; and elastic bodies biasing the abutting surface of at least one current collector toward a corresponding one of the electrode layers. The elastic bodies includes: a second base material surface being in contact with the first base material surface; and an elastic body protruding portion supporting the abutting surface and protruding from the second base material surface toward the corresponding one of the electrode layers to bias the abutting surface toward the corresponding one of the electrode layers.

    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 first 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 hydrogen included in a hydrogen-containing gas fed to the anode to move to the cathode and produces compressed hydrogen. One of the first end plates have a first channel formed therein, through which the hydrogen-containing gas fed to the anode flows, and a second channel formed therein, through which a heating medium flows. The compression apparatus further includes a heater that heats the heating medium.

    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 fuel cell system includes a fuel cell stack that generates electricity using fuel and oxidant gases, a reformer that produces the fuel gas by reforming a raw material, a raw material feeder that supplies the raw material to the reformer, a combustor that combusts anode off-gas discharged from the anode of the fuel cell stack, and a controller that controls the raw material feeder. The period of a load-following operation in which the power output of the fuel cell stack shifts from a lower level to a higher level, is divided into multiple sub-periods. For each sub-period, a ratio is determined from the increase amounts in the flow rate of the raw material during the sub-period and the length of the sub-period. The controller controls the raw material feeder to make a ratio on the higher output side smaller than another on the lower output side.
