Fuel cell system
Abstract
Disclosed is a fuel cell system comprising a fuel tank 11 for storing fuel; an evaporator 12 for evaporating the fuel to generate fuel gas; a reforming reactor 13 for generating reforming gas containing hydrogen from the fuel gas; a combustor 14 for burning any one of the fuel and the reforming gas to supply heat to the evaporator 12; and a fuel cell portion 15 for generating electricity by use of the hydrogen contained in the reforming gas generated in the reforming reactor 13, wherein a boiling point temperature of the fuel in the evaporator 12 is estimated based on an operation pressure of the evaporator 12, a vapor temperature of the fuel gas in the evaporator 12 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 14 is increased.
