Abstract

A device for producing an organic hydride 10 of an aspect of the present invention has an electrochemical cell provided with an anode 12 on a surface of an electrolyte membrane 11 and a cathode including a cathode catalyst layer 13 and a cathode diffusion layer 14 on another surface of the electrolyte membrane 11 . A gap is provided between the anode 12 and the electrolyte membrane 11 . The anode 12 has a network structure with an aperture ratio of 30 to 70%, and has an electrical supply supporting material formed of an electronic conductor and the electrode catalyst held by the electrical supply supporting material.

First claim

The invention claimed is:

a solid polymer electrolyte membrane having proton conductivity;
a cathode that is provided on a surface of the solid polymer electrolyte membrane and contains an electrolytic-hydrogenation catalyst for reducing a substance to be hydrogenated to produce a hydride;
a cathode chamber that accommodates the cathode and into which the substance to be hydrogenated is supplied;
an anode that is provided above another surface of the solid polymer electrolyte membrane and contains an electrode catalyst for oxidizing water to produce protons; and
an anode chamber that accommodates the anode and into which an electrolytic solution is supplied, wherein
a gap is formed between the anode and the electrolyte membrane,
wherein the electrode catalyst includes a solid solution of iridium oxide and tantalum oxide,
wherein the anode has a network structure with an aperture ratio of 30 to 70%, and has an electrical supply supporting material formed of an electronic conductor and the electrode catalyst held by the electrical supply supporting material,
wherein the anode has a rhombic aperture shape with a distance between centers in a short direction of 0.1 to 4 mm and a distance between centers in a long direction of 0.1 to 6 mm, and
wherein the gap is 0.02 to 0.2 mm.

2. The device for producing an organic hydride according to claim 1 , wherein the electrolytic solution is any of sulfuric acid, phosphoric acid, nitric acid, and hydrochloric acid, which has an ion conductance measured at 20° C. of 0.01 S/cm or more.

3. The device for producing an organic hydride according to claim 1 , wherein a gap is provided between the anode and the solid polymer electrolyte membrane.

4. The device for producing an organic hydride according to claim 1 , wherein an spacer is disposed between the anode and the solid polymer electrolyte membrane.
