<P>PROBLEM TO BE SOLVED: To provide a fuel flow rate control system capable of suitably utilizing in a fuel cell where a boiling-off gas is utilized as part of a fuel, in the fuel flow rate control system for controlling fuel characteristics supplied to the fuel cell before load variations to the fuel cell is generated. <P>SOLUTION: In the fuel flow rate control system having a fuel flow rate control section and a fuel flow rate-changed amount calculation section, the fuel flow rate-changed amount calculation section outputs a value subtracting a measured value from a necessary flow rate calculated from temperature of the fuel cell and the load applied to the fuel cell as a fuel flow rate-changed amount when pressure of the boiling-off gas is less than designated pressure, and outputs a value subtracting the measured value from the sum of a bias flow rate calculated from a difference of a calorific value between the boiling-off gas and an admixture of hydrocarbon gas as a fuel flow rate-changed amount when pressure of the boiling-off gas is designated pressure or more. <P>COPYRIGHT: (C)2010,JPO&INPIT |
