    摘要: An electrochemical cell includes a working electrode, a counter electrode, and an electrolyte covering the working electrode and the counter electrode. The working electrode and the counter electrode are configured so that electrons are supplied from the counter electrode to the working electrode and the working electrode absorbs CO2 in response to a first voltage applied between the working electrode and the counter electrode, and electrons are supplied from the working electrode to the counter electrode and the CO2 is desorbed from the working electrode in response to a second voltage applied between the working electrode and the counter electrode. The working electrode is made of a metal, and a surface of the working electrode that is to be in contact with the CO2 containing gas is covered with an oxide film.

    摘要: A fuel cell has an anode, a cathode and a solid electrolyte layer. The cathode contains a perovskite oxide as a main component. The perovskite oxide is expressed by a general formula ABO3 and includes at least Sr at the A site. The solid electrolyte layer is disposed between the anode and the cathode. The cathode includes a surface region which is within 5 μm from a surface opposite the solid electrolyte layer. The surface region contains a main phase comprising the perovskite oxide and a secondary phase comprising strontium sulfate. An occupied surface area ratio of the secondary phase in a cross section of the surface region is greater than or equal to 0.25% to less than or equal to 8.5%.
