Patent ID: 7090043

Claim:
A vehicle comprising: an oxides-of-nitrogen (NOx) trap assembly having an adsorption material which is regenerated with a mixture including hydrogen and carbon monoxide (syngas); a fuel cell power plant receiving air at an air inlet, receiving a hydrogen rich fuel mixture at a fuel inlet, and having humidified air exhausting from an air exit, said fuel cell power plant providing electrical power to operate auxiliary apparatus in said vehicle; an internal combustion engine system which operates on engine fuel and provides engine exhaust having NOx therein to said NOx trap assembly; means for generating syngas from said engine exhaust, said engine fuel and humidified air exhausting from said fuel cell power plant, in an amount in excess of that required to regenerate adsorption material in said NOx trap assembly; and a palladium membrane separator receiving at its input syngas and (a) providing syngas from a main output thereof for use in regenerating said adsorption material, and (b) providing a hydrogen rich gas mixture from an additional output of said separator to said fuel inlet of said fuel cell stack.
