Recent advances in the researches of anode, cathode, solid electrolyte, seperator support tube and the interconnector for solid oxide fuel cell are summarized. The problem existed is pointed out.
An anode catalyst layer of a direct liquid feed fuel cell includes a Pt-Ru or Pt-Pd black catalyst; and a supported Pt-Ru or Pt-Pd catalyst having Pt-Ru or Pt-Pd supported on a carbon-based support.
