A fuel for use in a fuel cell system which contains hydrocarbon compounds having four carbon atoms in an amount of 15 vol % or less, hydrocarbon compounds having five carbon atoms in an amount of 5 vol % or more, hydrocarbon compounds having six carbon atoms in an amount of 10 vol % or more, hydrocarbon compounds having seven or eight carbon atoms in an total amount of 20 vol % or more, and hydrocarbon compounds having ten or more carbon atoms in an amount of 20 vol % or less. The fuel exhibits an increased energy output generated per it s weight and per amount of CO2 formed, an improved fuel consumption, a decreased evaporative emission, good handling properties such as good storage stability and a suitable flash point, and reduced calories required for preheating. Further, the fuel allows a fuel cell system using the fuel to keep its initial performance for a long period of time, since it reduces the deterioration of a fuel cell system including a reforming catalyst, a water gas shift reaction catalyst, a carbon monoxide removal catalyst and a fuel cell stack. |
