Patent ID: 7208239

Claim:
A fuel cell arrangement comprising: a fuel cell system including an oxidizer inlet, a first fuel inlet, a high temperature fuel cell, and a low temperature fuel cell, wherein said high temperature fuel cell has an oxidizer inlet, a fuel inlet, an exhaust outlet and a nitrogen oxide outlet, and wherein said low temperature fuel cell has an oxidizer inlet; an oxygen generator having an air inlet that is adapted to receive air, and an outlet that is adapted to provide an oxygen-enriched output gas and that is connected to said oxidizer inlet of said fuel cell system, which connects to at least said oxidizer inlet of said high temperature fuel cell and said oxidizer inlet of said low temperature fuel cell; a hydrocarbon fuel supply that is adapted to supply a hydrocarbon fuel and that is connected to said first fuel inlet of said fuel cell system, which connects to said fuel inlet of said high temperature fuel cell; and a catalytic converter connected to said nitrogen oxide outlet of said high temperature fuel cell.
