の保護に関しては考慮されてなかった。As described in Japanese Patent Publication No. Sho 62-17958, the conventional technology is that when starting up a fuel cell, when the power charged in the secondary battery is being supplied to the load via an orthogonal converter, the load due to an accident on the load side is If the secondary battery is full of power at the time of shutdown, the remaining power in the fuel cell cannot be absorbed by the secondary battery, and there is no other device to absorb or consume this remaining power, so the fuel No consideration was given to protection against overvoltage due to remaining battery power.

あった。When the fuel cell 1 is generating output, the switching element T
h1 is turned on, a charging current is passed through the secondary battery 4, and the power generated by the fuel cell 1 is stored in the secondary battery 4, and then
The switching element T h 2 and the orthogonal converter 2 are turned on, and the DC output that was charging the secondary battery 4 is transferred to the load 3.
However, the conventional technology shown in Fig. 3 does not take into account the consumption or absorption of the remaining power of the fuel cell 1 at the time of load cutoff, and it is possible that an accident may occur on the load 3 side. If this occurs, it is necessary to immediately turn off the orthogonal converter 2 to prevent the accident from spreading, and at this point, the secondary battery 4
If the power stored in the fuel cell 1 is not supplied to the load 3 and the battery is in a full state, the secondary battery will no longer be able to absorb the remaining power generated by the fuel cell 1, and the remaining power will be consumed by other devices. Therefore, there was a problem in that the fuel cell 1 was exposed to overvoltage and the cell stack could be destroyed.

れる。[Means for solving the problem] The above purpose is to absorb all the remaining power generated by the fuel cell in the secondary battery when the load is cut off or stopped, and to use the power absorbed by the secondary battery as fuel. I! When the pond is started up, it is supplied to raise the temperature of the fuel cell via an electric heater, and all the electricity stored in the secondary battery is discharged before the fuel cell starts supplying reaction gas and generates voltage. This is achieved by allowing the secondary battery to absorb the remaining power generated by the fuel cell when the load is cut off or when the fuel cell is stopped.

できるので、起動過程における負荷遮断に対しても問題
はなくなる。The secondary battery that absorbs the remaining power of the fuel cell when the load is cut off or stopped is connected to an electric heater that is used as a heating source to raise the temperature at startup, and the power that was absorbed by the secondary battery is used to raise the temperature. At the same time, it is consumed through an electric heater. Following this, the startup
In addition, during normal operation, the secondary battery is in a fully discharged state, so it can sufficiently cope with absorption of residual power during load shedding, so there is no problem with load shedding during the startup process.

B4 is turned on and power is supplied to the electric heater 6 connected to an external power source to raise the temperature of the fuel cell 1. When the fuel cell 1 starts generating voltage, the circuit breakers CBI and CB2 are turned on, and the output generated by the fuel cell 1 is supplied to the electric heater 5 to heat the fuel cell 1 to raise its temperature. The output of the fuel cell 1 further increases as the temperature rises, and more power is applied to the electric heater 5, so the temperature rise rate of the fuel cell 1 increases at an accelerated pace, and the startup time of the fuel cell 1 increases. This will contribute to shortening the time. Such a state is cyclically repeated until the optimum temperature at which the fuel cell 1 can perform rated discharge is reached.

状況は停止時でも同じ動作となる。At startup or during load shedding when an accident occurs on the load 3 side during normal operation, the orthogonal converter 2 is turned off and circuit breakers CBI and CB2 are turned on to reduce the residual energy generated by the fuel cell 1. The power is absorbed by the secondary battery 4. This situation is the same even when stopped.
