ELECTROCHEMICAL REDUCTION DEVICE

摘要

An electrochemical reduction device includes: an electrolyte membrane; a reduction electrode including a reduction electrode catalyst layer, a diffusion layer, and a dense layer provided between the diffusion layer and the reduction electrode catalyst layer; an oxygen generating electrode; a raw material supplier that supplies the aromatic compound in a liquid state to the reduction electrode; a moisture supplier that supplies water or humidified gas to the oxygen generating electrode; and a power controller that externally applies an electric field such that the reduction electrode has an electronegative potential and the oxygen generating electrode has an electropositive potential.

1. An electrochemical reduction device comprising:
an electrolyte membrane having proton conductivity; a reduction electrode including a reduction electrode catalyst layer that is provided in contact with one major surface of the electrolyte membrane and has an electron conductive material and a metal containing one or both of Pt and Pd supported by the electron conductive material, a diffusion layer that is provided near to the other major surface of the reduction electrode catalyst layer, the other major surface being opposite to the electrolyte membrane, and that causes a liquid aromatic compound and a hydride of the aromatic compound to pass through, and a dense layer provided between the diffusion layer and the reduction electrode catalyst layer; an oxygen generating electrode provided in contact with the other major surface of the electrolyte membrane; a raw material supplier that supplies the aromatic compound in a liquid state to the reduction electrode; a moisture supplier that supplies water or humidified gas to the oxygen generating electrode; and a power controller that externally applies an electric field such that the reduction electrode has an electronegative potential and the oxygen generating electrode has an electropositive potential.
