Abstract
The present invention relates to a method and system for controlling a stop mode of a fuel cell. In particular, the present invention provides a method and system for controlling a stop mode of a fuel cell which are characterized by calculating the degree of deterioration of a fuel cell, determining a stopping voltage in accordance with the calculated degree of deterioration, and controlling an output voltage of the fuel cell to be the determined stopping voltage.
Claims13
A method of controlling a stop mode of a fuel cell, the method comprising:
- calculating a degree of deterioration of the fuel cell;
- determining a stopping voltage of the fuel cell in accordance with the calculated degree of deterioration;
- determining whether the fuel cell has entered the stop mode;
- and
- controlling an output voltage of the fuel cell to be the determined stopping voltage when it is determined that the fuel cell has entered the stop mode.
