During normal operation of a truck engine (12), a catalytic partial oxidizer (30) provides syngas (hydrogen and carbon monoxide) to regenerate NOx traps (35), for brief periods of time, or diverted (33) to the inlet (13) of an engine (12) via the EGR system (43-46). Some hydrogen is extracted from syng as by a palladium membrane separator (63) and passed to the fuel inlet (52) of a fuel cell stack (51). The stack (51) provides auxiliary electric power to th e truck. Humid air from the air outlet (55) of the stack is provided to a fuel/exhaust/air static mixer (25). A methanator (66) may convert CO, leaked through the palladium membranes, into CH4, Water/gas shift or steam reformer catalyst (76) at the inlet to or inside of the palladium membranes separator may provide some additional H2.
