摘要： The method for controlling an organic hydride generation system includes controlling potentials in an anode electrode and a cathode electrode such that a potential change in an electrode having a higher deterioration rate among the anode electrode and the cathode electrode included in an electrolytic bath is smaller than a potential change in an electrode having a lower deterioration rate.

摘要： An organic hydride production device comprises: an electrolyzer having an anode electrode that oxidizes water to generate a proton, a cathode electrode that hydrogenates a substance to be hydrogenated with the proton to generate an organic hydride, and a membrane that moves the proton together with dragged water from the side of the anode electrode to the side of the cathode electrode; an anolyte supplier that supplies the anolyte to the anode electrode; a water separator that separates the dragged water from the catholyte fed from the cathode electrode; and a water returner that sends the dragged water separated by the water separator to the anolyte supplier.

摘要： A cathode catalyst layer includes a cathode catalyst to hydrogenate a substance to be hydrogenated and a water repellent including an aggregate of arbitrary primary particles, the water repellent having a higher affinity for the substance to be hydrogenated and an organic hydride than for water. A volume fraction of the water repellent in the cathode catalyst layer is higher than 10 vol % with respect to the volume of the total solid content of the cathode catalyst layer.

摘要： An organic hydride generation system includes an electrolytic bath, a main power supplier, an auxiliary power supplier, a detector to detect a voltage of the electrolytic bath, a potential of an anode electrode, or a potential of a cathode electrode, and a controller to control the supply of power to the electrolytic bath. When it is detected that the voltage or the potential has changed to a specified value during operation stop of the organic hydride generation system in which the power from the main power supplier is not supplied to the electrolytic bath, the controller controls the auxiliary power supplier so as to supply the power to the electrolytic bath.
