Abstract
Disclosed is a voltage detection system of a fuel cell stack, which includes: a stack detection unit comparing input voltage and reference voltage when voltage of a fuel cell stack is input, and outputting a comparison result; and a determination unit determining whether negative voltage is generated in the fuel cell stack based on output voltage of the stack detection unit and a reference duty used for generation of the reference voltage.
Claims11
A voltage detection system of a fuel cell stack, comprising:
- a stack detection unit comparing an input voltage and a reference voltage when a voltage of a fuel cell stack is input and outputting a comparison result;
- and
- a determination unit determining whether negative voltage is generated in the fuel cell stack based on an output voltage of the stack detection unit and a reference duty used for generation of the reference voltage.
A method of detecting voltage of a fuel cell stack, comprising:
- receiving voltage of a fuel cell stack;
- comparing an input voltage and a reference voltage;
- and
- determining whether negative voltage is generated in the fuel cell stack based on a comparison result of the comparison step and a reference duty used for generation of the reference voltage.
