| 摘要 |
A fuel for a fuel cell system comprises wherein said fuel comprises hydrocarbons comprising 60 mol. % or more of saturates, 40 mol. % or less of olefins, 0.5 mol. % or less of butadiene, 0.1 mol. % or more of isoparaffin in saturates having carbon atoms of 4 or more and being a gaseous phase under normal temperature and pressure. 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, a small evaporative gas (evapo-emission), small deterioration of a fuel cell system comprising such as a reforming catalyst, a water gas shift reaction catalyst, a carbon monoxide removal catalyst, fuel cell stacks and the like to maintain the initial performances for a long duration, good handling properties in view of storage stability and inflammability, and a low preheating heat quantity. |
