ELECTROCHEMICAL CELL AND HYDROCARBON MANUFACTURING APPARATUS

Japanese Patent JP2023056800

A

To provide an electrochemical cell used for the production of a hydrocarbon by co-electrolysis with carbon dioxide and water vapor.SOLUTION: An electrochemical cell 1 comprises a cathode 2 and an anode 3 arranged on two opposite surfaces 12 and 13 of an oxide ion conductor 11. The cathode 2 has a laminated structure, in which a conductive metallic layer 2A that is configured with a first particle 21 having silver as a principal component and is arranged so as to contact a raw material gas G including carbon dioxide and water vapor, a complex oxide layer 2B that is configured with a second particle 22 having a complex oxide including a transition metal element as a principal component and is arranged so as to contact the oxide ion conductor 11, and an interlayer 2C that is arranged between the conductive metallic layer 2A and the complex oxide layer 2B and is configured with the first particle 21 and the second particle 22 are stacked.SELECTED DRAWING: Figure 1
