Abstract

A fuel for a fuel cell system, which comprises at least 5 vol. % of hydrocarbons based on the whole fuel and 0.5 to 20 mass % of oxygenates in terms of an oxygen content based on the whole fuel, wherein the total content of hydrocarbon compounds which have carbon numbers of 7 and 8 is 20 vol. % or more based on the whole hydrocarbons and the total content of hydrocarbon compounds which have carbon numbers of 10 or more is 20 vol. % or less based on the whole hydrocarbons, and a fuel for a fuel cell system, which comprises at least 5 vol. % of hydrocarbons based on the whole fuel and 0.5 to 20 mass % of oxygenates in terms of an oxygen content based on the whole fuel, wherein the fuel has distillation properties; the initial boiling point in distillation of over 40° C. and 100° C. or lower, the 10 vol. % distillation temperature of over 50° C. and 120° C. or lower, the 90 vol. % distillation temperature of 110° C. or higher and 180° C. or lower, and the final boiling point in distillation of 130° C. or higher and 210° C. or lower. The fuel for a fuel cell system has a high power generation quantity per weight, a high power generation quantity per CO2 emission, a low fuel consumption…
