Abstract
A method of preparing a fuel cell element includes the steps of: laminating ceramic tapes to form an unfired anode/electrolyte laminate; reducing the thickness of the anode/electrolyte laminate; sintering the anode/electrolyte laminate; laminating ceramic tapes to form an unfired cathode/interconnect laminate; reducing the thickness of the cathode/interconnect laminate; embossing a gas flow path pattern into the cathode layer of the cathode/interconnect laminate; sintering the cathode/interconnect laminate; and bonding the sintered anode/electrolyte laminate to the sintered cathode/interconnect laminate such that the electrolyte layer contacts the cathode layer. The fuel cell produced by this method has thin electrolyte and interconnect layers which result in high fuel cell outlet power.
