Fuel cell waste energy recovery combustor

摘要

The waste energy recovery assembly (24) for a fuel cell system (10) comprises: a cathode exhaust gas passage (54) in fluid communication with a mixing zone (64) through a collection chamber (60); an anode exhaust gas passage (56) in fluid communication with said mixing zone (64) by way of an anode exhaust gas orifice (66) disposed in a direction capable of forming an anode exhaust gas (38)flow entering said mixing zone (64) at an angle of about 45° to about 135° to a combined gas (80) flow entering said mixing zone (64) from said collection chamber (60); a thermal exchange structure (48)in fluid communication with said mixing zone (64); and an exhaust passage (70)in fluid communication with said thermal exchange structure (48).
