Abstract
A solid oxide fuel cell anode is comprised of a nickel foam or nickel felt substrate. Ceramic material such as yttria stabilized zirconia or the like is entrained within the pores of the substrate. The resulting anode achieves excellent conductivity, strength and low coefficient of thermal expansion characteristics while effectively reducing the overall quantity of nickel contained in the fuel cell. Equivalent or better fuel cell anode characteristics result in the present invention as compared to conventional anode designs while simultaneously employing significantly less nickel.
