Direct lamination of solid oxide fuel cell anode support, anode, and electrolyte by sequential tape casting of thermoreversible gel slips
A novel direct lamination technique by tape casting thermoreversible gel-based slips is introduced for the production of solid oxide fuel cell anode support, anode, and electrolyte layers. Production of cells with controlled layer thicknesses of similar to 10-500 mu m and having well formed and relatively high toughness interfaces is demonstrated. Cells with maximum current density of 1.76 A.cm(-2) and maximum power density 425 mW cm(-2) were achieved using 97% H-2/3% H2O fuel at 800 degrees C. Specific opportunities for further optimization of processing to improve electrochemical performance are highlighted. (C) 2012 Elsevier B.V. All rights reserved.
