Tape Cast Solid-Oxide Fuel Cells for the Direct Oxidation of Hydrocarbons

A tape casting method for fabricating solid-oxide fuel cells (SOFCs) that are active for the direct oxidation of dry hydrocarbons is presented. The method relies on the inclusion of pyrolyzable pore formers in the anode green tape in order to produce a porous yttria-stabilized zirconia anode matrix. Wet impregnation was used to add both a metal current collector and an oxidation catalyst to the anode. The performance characteristics for cells produced using this method while operating on and are presented. © 2001 The Electrochemical Society. All rights reserved.
