    摘要: Rapid response to a fuel cell system of the type including a reformer (32) in response to a change in load is achieved in a system that includes a fuel tank (24), a water tank (20) and a source (42) of a fluid at an elevated temperature. A heat exchanger (28) is provided for vaporizing fuel and water and delivering the resulting vapor to the system reformer (32) and includes an inlet (64) and an outlet (66) for the fluid. It includes a plurality of fluid flow paths (100), (102), (104) extending between the inlet (64) and outlet (66) as well as a fuel inlet (56) and a fuel outlet (58) spaced therefrom. The fuel inlet (56) and outlet (58) are connected by a plurality of fuel flow paths (52) that are in heat exchange relation with the fluid flow paths (100), (102), (104) and the fuel water inlet (56) is located adjacent the upstream ends of the fluid flow paths (100), (102), (104).

    摘要: A fuel humidifier/pre-heater system (10) is provided for pre-heating and humidifying a fuel flow, and is particularly useful for pre-heating and humidifying a fuel flow for a fuel cell, particularly molten-carbonate fuel cells (60). The system includes a steam generator (12), a water bypass (18), a liquid/steam mixer (20), and a mixture heater (14). The humidified fuel outlet temperature of the system is controlled by bypassing a portion of the water flow around the steam generator (12) so as to control the amount of superheat. The steam is then mixed with the fuel, and then the fuel/steam mixture is heated in the mixture heater (14). Additionally, a fuel bypass (16) can be provided for further temperature control by bypassing a portion of the fuel around the mixture heater (14) and then mixing the bypassed fuel with the steam/fuel mixture that has passed through the mixture heater (14).

    摘要: An integrated autothermal reformer/recuperator unit (10) is provided for reforming a feed gas flow to produce a reformate flow. The unit (10) includes a cylindrical housing (18) having a feed gas inlet (26) and a reformate flow outlet (32) located adjacent a first end (20) of the cylindrical housing (18). An autothermal reformer catalyst structure (12) is located in the housing and spaced from the first end, and a recuperator heat exchanger (16) is located in the housing (18) between the first end (20) and the catalyst structure (12).
