Abstract:
1. A fuel reforming system of a fuel cell system, comprising: a combustor comprising: a fuel reforming device provided downstream of the combustor, the fuel reforming device comprising: wherein the fuel reforming system is adapted to, (a) subject, when the fuel cell system starts, predetermined amounts of fuel and air for generating heat required in the fuel pre-vaporization part to the first lean combustion in the sub-combustion part, (b) pre-vaporize fuel to be combusted in the main combustion part in the fuel pre-vaporization part by use of a first combustion gas generated by the first lean combustion in the sub-combustion part, (c) subject air and the pre-vaporized fuel obtained by the pre-vaporization in the fuel pre-vaporization part to a second lean combustion in the main combustion part, and (d) heat, with a second combustion gas generated by the second lean combustion in the main combustion part, the fuel reformer of the fuel reforming device.
