PROBLEM TO BE SOLVED: To prevent dew condensation water from being supplied to a raw fuel supply device in a fuel cell system having a hydrodesulfurization recycling path, thereby enabling fuel gas to be circulated in a simple configuration.SOLUTION: A fuel cell system comprises: a raw fuel supply device which sends raw fuel by force; a hydrogenation desulfurizer which removes sulfur included in a raw fuel sent by force from the raw fuel supply device; a hydrogen generator including a reformer which generates fuel gas by reforming the raw fuel which has had sulfur removed by the hydrogenation desulfurizer; a fuel cell which causes the fuel gas and an oxidant gas to react to generate electricity; a recycle path, branched from a downstream path of the reformer, which supplies part of the fuel gas to the hydrogenation desulfurizer; and an ejector which increases the flow velocity of the sulfur-containing raw fuel sent by force from the raw fuel supply device to bring in part of the fuel gas generated by the hydrogen generator and thereby supplies the raw fuel and part of the fuel gas to the hydrogenation desulfurizer. |
