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.
