Abstract: 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.

Abstract: An organic hydride production system includes: an electrolytic bath having a cathode chamber, a first cathode opening, and a second cathode opening, in which the first cathode opening is disposed below the second cathode opening; a catholyte supply device capable of switching between supply of a catholyte from the first cathode opening to the cathode chamber and supply of the catholyte from the second cathode opening to the cathode chamber; and a control device that controls the catholyte supply device so as to form an upflow of the catholyte in the cathode chamber in a steady state and form a downflow of the catholyte in the cathode chamber under a predetermined condition.

Abstract: A cathode catalyst layer includes a cathode catalyst to hydrogenate a substance to be hydrogenated, a porous catalyst support supporting the cathode catalyst, and a non-porous body including an aggregate of arbitrary primary particles. A volume fraction of the non-porous body 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.

Abstract: 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.

Abstract: An organic hydride production device comprises: a cathode chamber that equips a cathode electrode for hydrogenating a substance to be hydrogenated in a catholyte with a proton to produce an organic hydride; a cathode inlet that is connected to the cathode chamber and supplies an external catholyte into the cathode chamber; an upper cathode outlet that is connected to the cathode chamber and discharges the catholyte and hydrogen gas in the cathode chamber to the outside; and a lower cathode outlet that is connected to the cathode chamber below the upper cathode outlet and discharges the catholyte and water in the cathode chamber to the outside.
