Abstract
ITN proposes to create an innovative anode supported membrane electrode assembly (MEA) for solid oxide fuel cells (SOFCs) that is capable of long-term operation at low temperature by the direct oxidation of dry methane or syngas fuel without coke formation on the anode. ITN's MEA is more efficient, durable, reliable, versatile and economical than the state of the art because it is made with transformative manufacturing techniques?microwave sintering and energy optimized plasma deposition (EOPD). The proposed fuel-flexible, direct oxidation MEA is capable of power densities up to 2 W/cm2 at 600?C. ITN's EOPD of thin, conformal YSZ electrolytes creates a stress free interface between the anode and electrolyte which improves MEA durability, cycle-ability and cell performance. The MEAs produced in this research effort can be incorporated into SOFC stacks capable of producing power in the 1-3 kW range. Because the fuel is oxidized directly in the SOFC, without external fuel processing, the thermodynamic efficiencies from fuel source to DC output exceed 70%. Higher efficiencies translate to minimal cooling required as obtained by way of conduction through the stack to a radiator exposed to space and/or by anode exhaust flow.
