Tape cast solid oxide fuel cells for the direct oxidation of hydrocarbons

A tape casting method for fabricating solid oxide fuel cells (SOFCs) that a re active for the direct oxidation of dry hydrocarbons is presented. The me thod 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 oxi dation catalyst to the anode. The performance characteristics for cells pro duced using this method while operating on H-2, CH4, and C4H10 are presente d. (C) 2001 The Electrochemical Society.
