Claim 0:
1. An electrochemical hydrogen compression system, comprising:
a hydrogen supply source;
an electrochemical hydrogen compression device having a unit cell formed by an electrolyte film and an anode and a cathode provided on two surfaces of the electrolyte film, and compressing hydrogen by applying a current between the anode and the cathode; and
a supply pipeline guiding the hydrogen discharged from the hydrogen supply source to the electrochemical hydrogen compression device,
wherein the electrochemical hydrogen compression device has:
an inlet into which the hydrogen supplied from the hydrogen supply source flows;
an outlet from which unreacted hydrogen of the hydrogen flowing into the inlet is discharged; and
a cell unit in which the unit cell is laminated,
and further comprising:
a power supply supplying the current applied between the anode and the cathode;
an acquisition part acquiring information related to a wet state of the electrolyte film;
a regulation part regulating discharge of the hydrogen from the outlet; and
a control device controlling the regulation part;
a humidifier provided in the supply pipeline and humidifying the hydrogen flowing through the supply pipeline;
a distribution pipeline being a part of the supply pipeline and branching on a downstream side of the humidifier and connected to the electrochemical hydrogen compression device; and
a distribution control valve controlling a flow rate of the hydrogen in each distribution pipeline,
wherein the cell unit comprises a plurality of regions divided based on a temperature distribution during an operation of the electrochemical hydrogen compression device, and
at least one distribution pipeline is connected to each of the plurality of regions of the cell unit, and
wherein the control device controls the regulation part based on at least the wet state.
