Abstract
A water electrolysis system controls a power supply device for passing a current between an anode and a cathode in a water electrolysis stack, based on a hydrogen concentration detected by a concentration sensor provided in a discharge pipe at a location downstream of a pressure control valve.
Claims8
A water electrolysis system comprising:
- a water electrolysis stack including an electrolyte membrane, and an anode and a cathode that sandwich the electrolyte membrane;
- a power supply device configured to pass a current between the anode and the cathode;
- a pressure control valve configured to narrow a passage of a discharge pipe through which oxygen-containing gas flows, the oxygen-containing gas being discharged from the water electrolysis stack and containing oxygen gas generated by water electrolysis in the water electrolysis stack;
- a concentration sensor provided in the discharge pipe at a location downstream of the pressure control valve, and configured to detect a hydrogen concentration in the oxygen-containing gas;
- and
- a control device configured to control the power supply device,
- wherein the control device comprises one or more processors that execute computer-executable instructions stored in a memory, and the one or more processors execute the computer-executable instructions to cause the control device to adjust the current passed between the anode and the cathode based on the hydrogen concentration.
