摘要： An oxidizer that is usable with a fuel cell includes a catalyst, an inlet to communicate an oxidant flow, an injection tube to communicate an anode exhaust flow, a mixing tube and a divergent nozzle. The injection tube communicates the anode exhaust flow from the fuel cell into the oxidizer to produce a combined flow in which the anode exhaust flow is oriented in substantially the same direction as the oxidant flow and surrounded by the oxidant flow. The mixing tube is connected to the inlet to receive the combined flow and mix the oxidant flow and the anode exhaust flow mix together to produce a mixed flow. A cross-sectional flow area of the mixing tube is sized to prevent flashback. The divergent nozzle communicates the mixed flow to the catalyst.

摘要： A gas turbine engine combustor can downstream of a pre-mixer has a pre-mixer flowpath therein and circumferentially spaced apart swirling vanes disposed across the pre-mixer flowpath. A primary fuel injector is positioned for injecting fuel into the pre-mixer flowpath. A combustion chamber surrounded by an annular combustor liner disposed in supply flow communication with the pre-mixer. An annular trapped dual vortex cavity located at an upstream end of the combustor liner is defined between an annular aft wall, an annular forward wall, and a circular radially outer wall formed therebetween. A cavity opening at a radially inner end of the cavity is spaced apart from the radially outer wall. Air injection first holes are disposed through the forward wall and air injection second holes are disposed through the aft wall. Fuel injection holes are disposed through at least one of the forward and aft walls.

摘要： A fuel cell system includes a de-sulfurization tank, a reformer, a pressure monitoring device and a fuel cell stack. The de-sulfurization tank includes an agent that is adapted to remove sulfur compounds and is capable of undergoing a conditioning cycle. The tank includes an inlet to receive a first hydrocarbon flow and an outlet to provide a second hydrocarbon flow. The reformer is adapted to convert the second hydrocarbon flow into a reformate flow, which is received by the fuel cell stack. The pressure monitoring device monitors a pressure of the second hydrocarbon flow, a circuit of the fuel cell system is coupled to the pressure monitoring device to determine whether the conditioning of the tank is complete based on the pressure.
