Paper Title:
A New Method of Fabricating the Anode Powder for the Application of Solid Oxide Fuel Cells
  Abstract

This paper presents the development of anode substrates of solid oxide fuel cells (SOFCs), prepared by rotating electrode powder-making equipment to improve the efficiency of cells and the coking issue that appears in traditional Ni-YSZ composite anodes when operated with hydrocarbon fuel. Combining the advantage of good electronic conductivity, leading less carbon residue of copper and high temperature oxidation resistance of Cr or Ni, the anode substrate is designed with Cu-Ni and Cu-Cr alloys so that the cells are able to work within the service temperature of 800-1000 C. To optimize the properties of conductivity, less carbon deposition and heat resistance, this research has invented substrates of copper-based dual metal composite alloys which are different from ordinary anode cermet powder made of nickel-ceramic composites. This new anode powder of dual metal alloys is made by rotating electrode powder-making equipment, with the powders being sintered to porous substrates. Experimental results show that the substrate has a good porosity and an electrical conductivity.
