Abstract:
1. A fuel cell system comprising: a fuel cell stack having an anode-side and a cathode-side, said anode-side having an inlet for receiving fuel and an exit for discharging exhaust fuel gas, and said cathode-side having an inlet for receiving oxidant gas and an exit for discharging exhaust oxidant gas; a burner for burning oxidant and exhaust fuel gas and for delivering the resultant gas to the inlet of said cathode-side; a mixer/eductor for operating on and mixing the exhaust fuel gas from said exit of said anode-side and a supply of oxidant gas and delivering the resultant mixture to said burner, said mixer/eductor being adapted to operate and mix said exhaust fuel gas and supply of oxidant gas such that the difference between the pressure of said exhaust fuel gas at the exit of the anode-side and the pressure of the oxidant gas at the inlet of the cathode-side is reduced.
