Abstract
An embodiment of the invention provides a fuel supply control system to control a fuel cell system to work in a predetermined temperature range by controlling a fuel supply rate. The fuel supply control system includes a fuel supply controller and a fuel supply device. The fuel supply controller calculates a temperature variation slope to generate a first fuel supply rate by increasing or decreasing the predetermined fuel supply rate according to the relationship of system temperature and predetermined working temperature, and controls a fuel delivering rate of the fuel supply device according to the first fuel supply rate.
