摘要： PROBLEM TO BE SOLVED: To provide a fuel cell power generation system and its operation method, which uses unreformed fuel as fuel gas and controls carbon deposition on a fuel electrode without setting an inert gas tank for purge gas.
SOLUTION: When a power generation is processed using unreformed fuel and air at a fuel cell stack 9, the fuel cell power generation system can supply purge gas to a fuel electrode through a purge gas generating equipment 7 by having one or more pair of cell elements for the fuel cell stack 9, adjusting an amount of unmodified fuel by a fuel supplying means, adjusting an amount of air by an air supplying means and switching a supplying path. The unreformed fuel is directly supplied to the fuel cell electrode side when power generation is continued, and, while the power generation is stopped or the temperature of the fuel cell stack is decreased , the supply flow path is switched to supply unreformed fuel and air to the fuel cell electrode side as purge gas in the operation method of the fuel cell power generation system.
