PURPOSE:To improve electric generation efficiently of a fuel cell in a fuel cell's fuel controlling apparatus wherein a fuel controlling means to adjust the fuel supply amount to the fuel battery corresponding to the electric load of the fuel cell is installed and an adjusting means to adjust the fuel supply amount so as to become the fuel supply amount to the fuel cell slightly more by a prescribed margin ratio than the necessary fuel amount for electric load of the fuel cell is installed. CONSTITUTION:A detecting means 17 to detect electric load condition of a fuel cell 1 is installed and based on the detection result of the detecting means 17, the margin ratio L is made small value La in the case that the electric load alteration of the fuel cell is small. A correcting means 19 to alter the margin ratio L is installed, so that the margin ratio L is made large value Lb in the case that the electric load alteration of the fuel cell 1 is high. |
