PURPOSE:To provide a fuel cell power generation device in which absorbent changing frequency can be reduced by improving a utilization efficiency of absorbent in a desulfurizer. CONSTITUTION:A first piping line to introduce material fuel from the upstream of a desulfurizer 3 through the downstream of the desulfurizer 3 to a reformer 2 is provided. A second piping line to introduce the material fuel from the downstream of the desulfurizer 3 through the upstream of the desulfurizer 3 to the reformer is provided. The first piping line and the second piping line are changed between each other to introduce the material fuel to the desulfurizer 3 based on a sulfur density at the exit of the desulfurizer 3. |
