摘要： A compressor device includes: a compressor that causes, by applying a voltage between an anode and a cathode, hydrogen in an anode gas to move through an electrolyte membrane to the cathode and compresses the hydrogen; a regulator that regulates the temperature of the anode gas in the compressor; and a controller that controls the regulator to regulate the temperature of the anode gas at an outlet of the anode based on at least one of the pressure of a cathode gas or a current flowing between the anode and the cathode under the application of the voltage.

摘要： A compression apparatus includes at least one compression unit, a voltage applier, an anode end plate provided on an anode separator located at a first end in a direction of stacking, a cathode end plate provided on a cathode separator located at a second end in the direction of stacking, a first seal material that surrounds an outer periphery of the cathode, and a second seal material that surrounds an outer periphery of a first space in which to store compressed hydrogen, the first space being provided between the cathode end plate and the cathode separator located at the second end. The compression apparatus causes, by using the voltage applier to apply a voltage, protons taken out from an anode fluid that is supplied to the anode to move to the cathode via the electrolyte membrane and produces compressed hydrogen. An area of a region surrounded by the second seal material is larger than an area of a region surrounded by the first seal material.

摘要： 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.

摘要： 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.
