PROBLEM TO BE SOLVED: To provide a fuel battery system that can perform more proper temperature control of a hydrodesulfurizer as compared with a prior art when the hydrodesulfurizer is heated by exhaust gas.SOLUTION: A fuel battery system has a fuel battery for generating power by using air and fuel obtained by reforming raw material, a hydrodesulfurizer for removing sulfur components in raw material, a first heat-exchanger which has an air passage through which air flows and a first exhaust gas passage through which exhaust gas flows, and heat-exchanges the air and the exhaust gas, a second heat-exchanger which has an air passage and a second exhaust gas passage through which exhaust gas flows, and heat-exchanges the air and the exhaust gas, and a heater for heating the hydrodesulfurizer by using exhaust gas. The exhaust gas flows through the first exhaust gas passage of the first heat-exchanger, the heater and the second exhaust gas passage of the second heat-exchanger in this order, the air flows through the air passage of the second heat-exchanger, the air passage of the first heat-exchanger and the fuel battery in this order, and the first heat-exchanger and the second heat-exchanger are configured integrally with each other.SELECTED DRAWING: Figure 1 |
