Their SOFC system can be operated without consuming the anode fuel (a reductant) at temperatures near that of the engine exhaust to eliminate the need for reductant refilling and extra heating. The NO x concentration in the exhaust of an automotive gasoline engine with spark ignition can be as high as 4000 ppm.
