Title: Operation of fuel cell
Inventor: ITO KOJI
IPC: H01M8/04
Filed: 1988-05-12
Abstract: PURPOSE:To stop the flow of a load current and avoid the local abnormal temperature rise of a unit cell by providing multiple judging circuits and issuing a command signal when the fuel gas flow quantity or the oxidizer gas flow quantity is lower than the lower limit corresponding to the load current. CONSTITUTION:Lower limits of flow quantities of the fuel gas 9 and oxidizer gas 10 corresponding to a load current I are set in the % ratio. The flow quantities of the gases 9 and 10 are detected by flow quantity sensors 11 and 12, they are inputted to judging circuits 13 and 14 as actual values. On the other hand, the gases 9 and 10 are fed to a fuel cell 1, the cell 1 feeds the load current I to a load 7. The current I is detected by a current detector 5, its value 5A is inputted to the circuits 13 and 14. The circuits 13 and 14 compare the inputted actual values of the gases 9 and 10 with the lower limit values corresponding to the load current value 5A. When the actual values are lower than the lower limit values, the circuit 13 or 14 issues a command signal to a breaker 6 to open the breaker 6, the flow of the load current I is stopped.
