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 an electrolyte membrane, an anode on a principal surface of the electrolyte membrane, a cathode on another principal surface of the electrolyte membrane, an anode separator on the anode, a cathode separator on the cathode, and a voltage applicator. Upon the voltage applicator applying a voltage between the anode and the cathode, protons are extracted from an anode fluid fed to the anode to migrate to the cathode through the electrolyte membrane and compressed hydrogen is produced. The cathode separator has a first O-ring groove formed in a cathode-side principal surface of the cathode separator to surround a region of the cathode-side principal surface which faces the cathode. The compression apparatus includes a first O-ring held by the first O-ring groove and a face seal disposed on an outer periphery of a region of an anode-side principal surface of the anode separator which faces the anode.

Abstract: A hydrogen supply system includes: a controller; and an electrochemical hydrogen pump including: an electrolyte membrane; a pair of electrodes provided on two surfaces of the electrolyte membrane; and a current adjuster adjusting a current flowing between the electrodes, the electrochemical hydrogen pump performs a hydrogen supply operation supplying pressure-boosted hydrogen to a hydrogen demander by allowing a current to flow between the electrodes by the current adjuster; and when a cumulative hydrogen supply amount which is supplied to the hydrogen demander from start to completion of the hydrogen supply operation to the hydrogen demander from the electrochemical hydrogen pump is smaller than a cumulative hydrogen supply amount in another hydrogen supply operation, the controller controls the current adjuster so that the current flowing between the electrodes is decreased to be smaller than that in the another hydrogen supply operation.
