METAL-BASED SOLID OXIDE ELECTROCHEMICAL DEVICES

A solid oxide electrochemical device comprises a solid electrolyte layer, the first surface and second surface having surface pores formed therein; a first composite electrolyte layer composed of metal and a solid electrolyte and having a first porosity; a second composite electrolyte layer composed of metal and the solid electrolyte and having the first porosity, the solid electrolyte layer sandwiched between the first composite electrolyte layer and the second composite electrolyte layer; a cathode on one of the first composite electrolyte layer and the second composite electrolyte layer; and an anode on another of the first composite electrolyte layer and the second composite electrolyte layer. The anode comprises an anode metal layer comprising pores; anode active material; and reforming catalyst, wherein the anode active material and the reforming catalyst line walls of the pores in the anode metal layer.
