摘要： PROBLEM TO BE SOLVED: To provide an operation control device of a fuel cell suitable for lowering the current of a fuel cell without being affected by fluctuations of the load in the case the voltage of the fuel cell dropped.
SOLUTION: The cell voltage Ef of a fuel cell 1 is detected, and when it has dropped, a current command obtained by converting the power command value Pfc of the fuel cell 1 into a current is lowered. A current limiter 8 makes the current command value as a limit value, and lowers the limit value according to the drop of the Ef. As a specific limiting method of the current command value, the current command value is restricted so that the cell current Ifc starts to go down at a voltage drop alarm level (first threshold), and the cell current reaches zero at a voltage drop protection level (second threshold).

摘要： PROBLEM TO BE SOLVED: To solve a problem where, in a conventional technique, incoming power cannot be controlled because the incoming power is not detected, and the fuel consumption of a fuel cell frequently varies when its load rapidly changes because load power is used as it is, so that efficiency of the fuel cell may be degraded.
SOLUTION: Peak-cut operation is executed in a secondary battery Bat in order to control the incoming power. The load power is calculated from an incoming power detection value and command values of the secondary battery Bat inside control and a power generation facility, and used for command value creation for the fuel cell FC1 by putting a filter in the load power.

摘要： PROBLEM TO BE SOLVED: To stably operate a system by regulating the temperature of heat recovery water supplied to a heat exchange device from a tank at a constant value.
SOLUTION: A mixing valve 10b is installed at a connection point between a bypass line 10d for bypassing the entrance side and the exit side of the tank 10a and a heat recovery water circulation passage, and the opening of the mixing valve 10b is controlled by a controller 10e based on the detection temperature of a temperature sensor 13 for detecting the temperature of the heat recovery water 27 supplied to a cathode exhaust gas heat exchanger 11a. When the detection temperature of the temperature sensor 13 is lower than 30°C, the temperature of the heat recovery water 27 is raised by increasing the opening on the bypass line side of the mixing valve 10b and by reducing the opening on the hear recovery tank 10a side; on the contrary, when the detection temperature of the temperature sensor 13 is higher than 30°C, the temperature of the recovery water 27 is lowered by reducing the opening on the bypass side of the mixing valve 10b and by increasing the opening on the recovery tank 10a side; and thus the temperature of the heat recovery water supplied to the heat exchanger 11a is kept at 30°C.
