Abstract
The present invention utilizes an electrochemical catalyst which contains: a metal oxide that is composed of one or more compounds selected from among zirconium oxide, cerium oxide, yttrium oxide, gadolinium oxide, samarium oxide, cobalt oxide and scandium oxide; and a metal variant, which has a valence that is different from the valence of the metal that constitutes the metal oxide.

1-7. (canceled)
A hydrocarbon generation system, comprising a co-electrolysis cell and a hydrocarbon generation cell each connected to an external power source,
- wherein each of the co-electrolysis cell and the hydrocarbon generation cell has an electrochemical reactor, being configured to generate a hydrocarbon from carbon dioxide and water;
- the electrochemical reactor comprising:
- an oxygen-permeable electrolyte membrane, as well as
- a cathode and an anode disposed to either side of the electrolyte membrane,
- wherein the cathode is composed of an assembly;
- the assembly comprising an electrochemical catalyst and a conductive metal joined with each other to form an interface;
- and
- the electrochemical catalyst comprising:
- a metal oxide composed of one or two or more of zirconium oxide, cerium oxide, yttrium oxide, gadolinium oxide, samarium oxide, cobalt oxide and scandium oxide;
- and
- a metal variant, having a valence different from that of a metal composing the metal oxide.
