    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 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.
