An apparatus for estimating electrical properties of an electrolyzer includes a data processing system for estimating electrical values, for example a membrane resistance, of the electrolyzer based on a difference voltage, a current, and an initial value and an attenuation time constant of a double-layer capacitance voltage of the electrolyzer during a shutdown of the electrolyzer. The difference voltage is a difference between a voltage of the electrolyzer and a total reversible voltage of the electrolyzer. The initial value and the attenuation time constant of the double-layer capacitance voltage are estimated based on values of the difference voltage when the current is zero and thus the difference voltage equals the double-layer capacitance voltage. The electrical values can be estimated even if a stepwise interruption of the current of the electrolyzer is not possible.

An electrolysis device may include a housing having a cavity that is configured to receive a precursor solution. The precursor solution may include chloride. An electrolysis circuit may be located in the cavity of the housing. The electrolysis circuit may include a power source, a first electrode and a second electrode electrically coupled to the power source, and a control circuit electrically coupled to the power source and the first and second electrodes. Upon the control circuit being activated while the precursor liquid operably couples the first and second electrodes together, the electrolysis circuit may be configured to generate a hypochlorite solution from the precursor solution.

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.
