PURPOSE:To decrease the differential pressure between cell electrodes and the difference between the internal pressure of an auxiliary combustor and the discharge pressure of air treatment equipment in connection with every load variation of a cell by controlling the air pressure in each part of a system in relation to the operation of each part. CONSTITUTION:A system consists of air treatment equipment 1, a fuel cell 2, an auxiliary combustor 6, a reservoir tank 21, a fuel reformer 4, and relating pipelines, pressure detector, a flow detector, pressure control valves, and a valve controller 27. If the differential pressure between the combustor 6 and the equipment 1 is a specified value or less, a valve 20 is operated to control the inner pressure of the combustor 6. If the differential pressure exceeds a specified value, a valve 24 is operated to control the pressure of the tank 21. By comparison signal of the inner pressure of the combustor 6 to a specified value, if the pressure of the tank 21 is a specified value or less, a valve 19 is operated, and if it exceeds a specified value, a valve 25 is operated. Thereby, the differential pressure between electrodes of the cell 2 is constantly decreased and the combustor 6 is steadily operated. |
