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 feeder that supplies fuel, a fuel cell stack that generates power through an electrochemical reaction using air and a hydrogen-containing gas generated from the fuel, a first temperature sensor that senses the temperature of the fuel cell stack, and a controller. The fuel cell stack has a membrane electrode assembly including an electrolyte membrane through which protons can pass, a cathode on one side of the electrolyte membrane, and an anode on the other side of the electrolyte membrane. The controller defines an upper limit of current output from the fuel cell stack on the basis of the temperature of the fuel cell stack, the supply of the fuel, and the hydrogen consumption of the fuel cell stack associated with internal leakage current and keeps the current output from the fuel cell stack at or below the upper limit.
