Abstract:
1. A fuel supply control method to control a fuel cell system to work in a predetermined temperature by controlling a fuel supply rate, wherein the fuel cell system comprises a fuel supply unit comprising a fuel tank storing highly concentrated fuel and a fuel deliver device delivering the highly concentrated fuel from the fuel tank to a fuel unit of the fuel cell system to replenish the used fuel and keep the fuel cell system operated at predetermined working temperature thereof, the fuel supply control method comprising: setting a predetermined fuel supply rate; setting a predetermined working temperature; detecting a system temperature of a fuel cell system; calculating a temperature variation slope of the system temperature; generating a first fuel supply rate by increasing or decreasing a predetermined fuel supply rate according to the relationship of system temperature and predetermined working temperature; and controlling a fuel delivering rate of the fuel deliver device according to the first fuel supply rate.
