    摘要: Fuel cell current is sensed (30) and during a transient, a feed forward demand signal (50) sent to the fuel flow regulator (58). A nominal desired reformer temperature is established for the new fuel cell current. This desired temperature signal (62) is dynamically compensated (64) to establish the operating temperature set point (72). A predominantly lead compensation (66) is achieved for a desired temperature increase and a predominantly lag compensation (68) for a desired temperature decrease. Increased reliance on the temperature as a result of the system input reduces reliance on the accuracy of fuel flow measurement and on the consistency of fuel heating value.
