Abstract

PURPOSE:To enhance the power generating efficiency by allowing all the residual electric power generated by a fuel battery to be absorbed by a secondary battery when the load is shut off or at the time of stopping. CONSTITUTION:A breaker CB1 is installed between a fuel battery 1 and a DC/AC converter 2, and the power supply bus bar is diverged from the breaker CB1 by breakers CB2, CB3, and a secondary battery 4 and an electric heater 5 are connected via the breakers CB3, CB2, respectively. When the load is shut off or at the time of stopping, the secondary battery 4 which has absorbed the residual electric power of the fuel battery 1 is connected with the mentioned electric heater 5 as heat source for temp. rise at the time of starting, and the electric power absorbed by the secondary battery 4 is consumed through the heater 5 at the time of temp. rise. Because the secondary battery 4 is in fully discharged condition at the time of starting or under normal operation subsequent thereto, good response can be offered to absorption of the residual electric power when the load is shut off. At such time, therefore, or even at the time of stopping, the electric power generated by the fuel battery can be absorbed, and this absorbed power is utilized at the time of temp. rise, which enhances the power generating efficiency.

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.

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.

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.
