Abstract:
1. A fuel cell power generation system comprising: a reformer which generates a hydrogen rich gas from a raw material by reforming reaction; raw material supply means of supplying the raw material to the reformer; temperature control means of controlling the temperature of the reformer so as to promote the reforming reaction; temperature detection means of detecting the temperature of the reformer; a fuel cell in which electric power is generated by using the hydrogen rich gas; and control means of controlling the operations of the reformer, the raw material supply means, the temperature control means and the fuel cell on the basis of the temperature detected by the temperature detection means, wherein when the operation of the fuel cell is stopped, the control means performs such control that the temperature of the reformer is equal to or lower than a predetermined temperature, while at least the raw material supply means is continuing supply of the raw material, and the predetermined temperature is a temperature at which the hydrogen rich gas is not generated or the hydrogen rich gas is generated in such an amount as not to react with air.
