摘要： A fuel cell system includes a fuel cell. The fuel cell includes an anode having an anode inlet configured to receive anode feed gas, and an anode outlet configured to output anode exhaust. The fuel cell further includes a cathode having a cathode inlet and a cathode outlet. The fuel cell system further includes an anode blower configured to receive the anode exhaust and output a higher-pressure anode exhaust. The fuel cell system further includes an anode blower recycle line configured to receive a portion of the higher-pressure anode exhaust downstream from the anode blower and to output the portion of the higher-pressure anode exhaust upstream from the anode blower. The fuel cell system further includes a first valve disposed in the blower recycle line, the first valve configured to open when the anode of the fuel cell is under-pressurized.

摘要： A mixer/eductor assembly for use with a fuel cell stack having an anode-side and a cathode-side, said mixer/eductor assembly mixing and at least partially combusting anode exhaust gas output from the anode-side and an oxidant supply gas, said mixer/eductor assembly comprising: a first area receiving and mixing a first portion of the anode exhaust gas and a first portion of the oxidant supply gas to form a first mixture, the first area being configured so as to initiate a combustion reaction in the first mixture; a second area coupled with the first area, the second area receiving to and mixing a second portion of the anode exhaust gas and a second portion of the oxidant supply gas to form a second mixture, wherein: the first mixture has a predetermined oxidant to fuel ratio smaller than the oxidant to fuel ratio of the second mixture; and the first area provides an ignition source to promote continuous combustion of the second mixture in the second area.

摘要： A duct for a fuel cell module includes an upper duct hood having an inlet configured to receive reactant gas from a supply duct, the upper duct hood defining a first tapered portion and a second tapered portion. The duct further includes a lower duct hood fluidly coupled to the upper duct hood, the lower duct hood defining at least one outlet. In a side view, the second tapered portion is tapered inwardly in a downstream direction. In a top view, the first tapered portion is tapered inwardly in a downstream direction, and the second tapered portion is tapered outwardly moving downstream.
