Abstract
In a fuel reforming system () of a fuel cell system (), which includes a reformer () generating hydrogen-containing gas to be an electromotive fuel and a combustor () generating combustion gas, the combustor () has two combustion parts including a main combustion part () and a sub-combustion part (), a fuel pre-vaporization part () between the two combustion parts and a main fuel injection valve () and a sub-fuel injection valve () which supply the fuel to the respective combustion parts. In start-up of the fuel cell system (), predetermined amounts of fuel and air for generating heat quantity required in the fuel pre-vaporization part () are subjected to lean combustion in the sub-combustion part (), the fuel to be combusted in the main combustion part () is pre-vaporized in the fuel pre-vaporization part () by use of the combustion gas from the sub-combustion part (), and the pre-vaporized fuel obtained by the pre-vaporization and air are subjected to premixed lean combustion in the main combustion part ().
