Abstract
Disclosed is a fuel cell system comprising a fuel tank for storing fuel; an evaporator for evaporating the fuel to generate fuel gas; a reforming reactor for generating reforming gas containing hydrogen from the fuel gas; a combustor for burning any one of the fuel and the reforming gas to supply heat to the evaporator and a fuel cell portion for generating electricity by use of the hydrogen contained in the reforming gas generated in the reforming reactor wherein a boiling point temperature of the fuel in the evaporator is estimated based on an operation pressure of the evaporator a vapor temperature of the fuel gas in the evaporator is measured, and when a value obtained by subtracting the boiling point temperature from the vapor temperature becomes below a predetermined value, a flow rate of any one of the fuel and the reforming gas burnt in the combustor is increased.
