Abstract
The present invention provides a fuel cell system using combustion heat for an evaporator and a desulfurizer effectively. The fuel cell system comprises a combustor, a reformer, a fuel cell, a first cathode air heating part, a desulfurizer and an evaporator. A mixture of oxygen and gas which is contained in fuel is combusted in the combustor. A combustion exhaust gas generated in the combustor flows in the fuel cell system in such a manner that the combustion exhaust gas gives thermal energy to the reformer, the first cathode air heating part, the desulfurizer, and the evaporator in this order.
Claims19
A fuel cell system comprising:
- a combustor where a mixture of oxygen and gas which is contained in fuel is combusted;
- a reformer for generating a reformed gas to be used as the fuel through a reforming reaction from supplied gaseous fuel using a combustion exhaust gas generated in the combustor as a heat source;
- a fuel cell for generating electric power through a reaction of the reformed gas and an oxidation gas;
- a first cathode air heating part for heating the oxidation gas to be supplied to the fuel cell using the combustion exhaust gas which has heated the reformer as a heat source;
- a desulfurizer for removing a sulfur ingredient contained in the fuel to be supplied to the reformer using the combustion exhaust gas which has heated the first cathode air heating part as a heat source;
- and
- an evaporator for generating water vapor to be supplied to the reformer by evaporating a supplied water using the combustion exhaust gas which has heated the desulfurizer as a heat source.
