The invention provides an auxiliary power unit (APU) and process for electricity generation in combination with an internal combustion engine in which the APU includes a solid oxide fuel cell (SOFC) having an inlet for fuel, an inlet for air and/or engine exhaust gas, and an outlet for off-gas; and a catalytic partial oxidation reformer (CPOx) having an outlet which is connected to the inlet for fuel of the SOFC and an inlet for reactants, wherein the inlet for reactants is connected to an outlet for engine exhaust gas of the internal combustion engine through an evaporator having an inlet for fuel and an inlet for engine exhaust gas and an outlet which is connected to the inlet of the CPOx.

Process for generation of electricity from a solid oxide fuel cell auxiliary power unit using engine exhaust gas

Either (a) the exhaust () of an engine () and/or (b) inlet air () is sent to a hydrogen generator () along with diesel fuel () to produce hydrogen and carbon monoxide () for either (c) mixing with the mainstream of exhaust fed to a catalytic converter () or (d) regenerating a pair of NOx adsorption traps (), thereby reducing oxides of nitrogen (NOx) to provide system exhaust () which may have less than 0.20 grams/bhp/hr of NOx and 0.14 grams/bhp/hr of non-methane hydrocarbons. A water recovery unit () may extract water from either the exhaust or the effluent of the NOx traps to humidify inlet air () for mixture with fuel. Inlet air () may be humidified in an air bubbling humidifier () that receives water from a condenser () that uses inlet air to cool NOx trap effluent.
