Abstract
An electrochemical hydrogen compression system is equipped with a supply pathway communicating with an anode side of a unit cell, a discharge pathway communicating with a cathode side of the unit cell, a hydrogen return pathway guiding hydrogen to the supply pathway from a downstream side of a gas-liquid separator in the discharge pathway, and a control device. In the case that the electrical value indicative of a voltage or a resistance exceeds a predetermined threshold value when electrical current of the hydrogen compression stack is of a predetermined value, the control device opens a hydrogen return valve disposed in the hydrogen return pathway.
