Abstract
An electrochemical hydrogen compressor includes: a cell including a proton conductive electrolyte membrane having a pair of principal surfaces, a cathode disposed on a first one of the principal surfaces of the electrolyte membrane, and an anode disposed on a second one of the principal surfaces of the electrolyte membrane; a voltage applicator that applies a voltage between the anode and the cathode; a dew point adjuster that adjusts a dew point of a hydrogen-containing gas to be supplied to the anode; and a controller that, when the temperature of the cell increases, controls the dew point adjuster to increase the dew point of the hydrogen-containing gas.

An electrochemical hydrogen compressor comprising:
- a cell including a proton conductive electrolyte membrane having a pair of principal surfaces, a cathode disposed on a first one of the principal surfaces of the electrolyte membrane, and an anode disposed on a second one of the principal surfaces of the electrolyte membrane;
- a voltage applicator that applies a voltage between the anode and the cathode;
- a dew point adjuster that adjusts a dew point of a hydrogen-containing gas to be supplied to the anode;
- and
- a controller that, when the temperature of the cell increases, controls the dew point adjuster to increase the dew point of the hydrogen-containing gas.
A method for operating an electrochemical hydrogen compressor, the method comprising:
- (a) applying a voltage between an anode of a cell and a cathode of the cell to supply a compressed hydrogen gas from the anode to the cathode, the cell including a proton conductive electrolyte membrane having a pair of principal surfaces, the cathode disposed on a first one of the principal surfaces of the electrolyte membrane, and the anode disposed on a second one of the principal surfaces of the electrolyte membrane;
- and
- (b), when the temperature of the cell increases in (a), increasing the dew point of a hydrogen-containing gas to be supplied to the anode.
