Fuel electrode layer and electrochemical cell

Abstract

A fuel electrode layer of the present disclosure is used in a solid oxide-type electrochemical cell. The fuel electrode layer has catalyst material particles, solid electrolyte particles, and at least one metal M selected from a group consisting of metals having a standard electrode potential more negative than that of Ni. The catalyst material particle includes Ni as its primary component, and further includes the metal M. The solid electrolyte particle includes a ceria-based oxide as its primary component, and further includes the metal M. A solid oxide-type electrochemical cell of the present disclosure has the fuel electrode layer described above, a solid electrolyte layer, and an air electrode layer, which is formed as a counter electrode to the fuel electrode layer, in this order.
