... ) and a limited ability to thermal cycle (<200 cycles). Recently, a novel hybrid setup that combines a fuel-rich combustion reformer with a SOFC was developed and utilized to investigate rapid heating, cooling, and thermal cycling of a micro-tubular SOFC. In this work, 3000 moderate thermal cycles...

... of the cathode stream. The resulting efficiency penalty is below 2–3% with a CO 2 avoidance of about 74%, leading to a specific energy consumption for CO 2 avoided of 1.3 MJ/kg CO2 . This number is much lower than corresponding values for reference CO 2 capture technology as post-combustion scrubbing...
