    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).
