摘要： PROBLEM TO BE SOLVED: To provide a system and its operation method capable of continuous operation regardless of a thermal load, in a fuel cell exhaust heat utilization system using fuel cell exhaust heat for water heating/space heating and the like. SOLUTION: In the case of T2>42°C, the number of revolutions of a circulation pump P1 is reduced to reduce a flow rate of a primary circuit (S102). Thereby, a heat quantity supplied to a load heat exchanger 5 is reduced, and a heat supply quantity to a floor heating panel 6 being a secondary heat using facility is reduced. In the case of T2≤42°C, whether or not T2 is below 38°C is then determined (S103). In the case of NO, the operation is continued in that state (S105). In the case of YES, it shows that the temperature T4 of a secondary return path is below an allowable temperature range. Thereby, the number of revolutions of the circulation pump P1 is increased to increase the flow rate of the primary circuit (S104), and a heat quantity supplied to the heat exchanger 5 is increased.

摘要： PURPOSE:To restrain ignition when operations are suspended, and thereby purge flammable gas by connecting an air source to a point between the junction point of each air electrode and an exhaust heat recovery exchanger, and thereby mixing inert gas into the downstream side from a burner for pipelines. CONSTITUTION:The device is composed of a laminated body of unit cells in each of which a fuel electrode 3 and an air electrode 4 are disposed while an electrolytic matrix is being held in between, and fuel gas produced at a fuel reforming means 5 out of basic fuel A is fed to a fuel electrode 3. When air C is fed to the air electrode 4 furthermore, generation takes place based on electrochemical reaction. In this case, a purge means 10 is provided for the upstream side of the junction point P of fuel exhaust gas E in a pipeline L connecting the means 5 which is a part of the pipeline of a fuel system, to the exhaust heat recovery exchanger 7, and off-gas F at the air electrode 4. The means 10 forces inert gas to be mixed into the downstream side from the burner 6 of the pipeline of the fuel gas system for the fuel cell. Remaining flammable gas is restrained from being ignited when the fuel cell is ignited so as to be started, so that the system can thereby be completely purged.
