Abstract
A fuel cell system includes: a reformer operative to generate a reformed gas by using a raw material gas; a fuel cell operative to generate electric power by using the reformed gas from the reformer and air; a desulfurizer operative to perform hydrodesulfurization of the raw material gas; a recycled gas passage through which a part of the reformed gas is supplied as a recycled gas to a raw material gas passage provided upstream of the desulfurizer; and a heat exchanger operative to cause the recycled gas flowing through the recycled gas passage to perform heat exchange with one of the raw material gas and the air.
Claims8
A fuel cell system comprising:
- a reformer operative to generate a reformed gas by using a raw material gas;
- a solid-oxide fuel cell operative to generate electric power by using the reformed gas from the reformer and air;
- a desulfurizer operative to perform hydrodesulfurization of the raw material gas to be supplied to the reformer;
- a recycled gas passage through which a part of the reformed gas is supplied as a recycled gas to a raw material gas passage provided upstream of the desulfurizer;
- and
- a first heat exchanger operative to cause the recycled gas flowing through the recycled gas passage to perform heat exchange with the raw material gas, wherein
- the raw material gas flows through the first heat exchanger and the desulfurizer in this order.
