Abstract
An electrochemical hydrogen pump includes: a cell including a proton conductive electrolyte membrane having a first main surface and a second main surface, a cathode disposed on the first main surface of the proton conductive electrolyte membrane, and an anode disposed on the second main surface of the proton conductive electrolyte membrane; a voltage applier that applies a voltage between the anode and the cathode; a cooler that cools the cell; and a controller that controls the cooler to increase an amount of cooling per unit time of the cell when a pressure of a cathode gas flow path on the cathode increases.

An electrochemical hydrogen pump comprising:
- a cell including:
- a proton conductive electrolyte membrane having a first main surface and a second main surface,
- a cathode disposed on the first main surface of the proton conductive electrolyte membrane, and
- an anode disposed on the second main surface of the proton conductive electrolyte membrane;
- a voltage applier that applies a voltage between the anode and the cathode;
- a cooler that cools the cell;
- and
- a controller including a processor and a memory storing a control program, wherein the control program, when executed by the processor, causes the controller to control the cooler to increase an amount of cooling per unit time of the cell when a pressure of a cathode gas flow path on the cathode increases.
A method for operating an electrochemical hydrogen pump including a cell including:
