    摘要: The invention generally relates to a method and apparatus for collecting condensate from combustible gas process streams in an integrated fuel cell system. In one aspect, a water management subsystem for a fuel cell system has a first conduit containing a first gas at a first pressure. A first water trap is provided that is configured to receive condensate from the first conduit. A second conduit is provided that contains a second gas at a second pressure. A second water trap is provided that is configured to receive condensate from the second conduit and the first water trap.

    摘要: In one aspect, the invention provides a method and apparatus for thermal management in a fuel cell system. The fuel cell system includes a fuel cell or a fuel cell stack, and a coolant loop to remove heat from the stack. The coolant loop includes a radiator to remove heat from the coolant loop. The coolant loop also includes a liquid-to-liquid heat exchanger that can be used to remove heat form the coolant loop. The coolant from the coolant loop flows through a first side of the heat exchanger. The second side of the heat exchanger is not used by the fuel cell system, but rather is made available to systems outside the fuel cell system, which can circulate a fluid through the heat exchanger to heat the fluid.

    摘要: A system and method for enthalpy transfer in a fuel cell includes flowing a gas and liquid water through a thermally conductive conduit, flowing a relatively hot gas containing water vapor across an external portion of the conduit, and transferring enough heat from the hot gas to cool the hot gas below its dew point and to cause a portion of the liquid water in the conduit to evaporate.

    摘要: The invention generally relates to a method and apparatus for collecting condensate from process streams in an integrated fuel cell system. In one aspect, the invention provides a water management subsystem for a fuel cell system. A gas conduit contains a gas at a first pressure. A water tank in the system contains water at a certain level. The water tank has an inlet orifice below the water level. A drain conduit has a first end and a second end. The drain conduit is connected at the first end to the gas conduit, and the drain conduit is connected at the second end to the inlet orifice of the water tank. The water level and the inlet orifice have a vertical height of water between them corresponding to a head pressure greater than the first pressure.

In one aspect, a fuel cell system is provided that includes a fuel cell having an anode inlet adapted to receive a flow of anode gas from an anode inlet conduit, and a cathode inlet adapted to receive a flow of cathode gas from a cathode inlet conduit. A first heat exchange surface is adapted to contact the flow of anode gas within the anode inlet conduit, and a second heat exchange surface adapted to contact the flow of cathode gas within the cathode inlet conduit. A coolant system is adapted to circulate a coolant through a coolant conduit. The coolant system is adapted to transfer heat from each of the first and second heat exchange surfaces to the coolant.
