Abstract

The embodiment of the invention provides a system and method for sensing a fuel cell of a vehicle. The system for sensing the fuel cell of the vehicle may include: an analog digital converter (ADC) configured to receive a voltage of a fuel cell stack; a calculation unit configured to calculate a total number of cells of the fuel cell stack; and a control unit configured to acquire a voltage per a unit cell of the fuel cell stack based on output values of the ADC and the calculation unit.

Description

technical field [0001] The invention relates to a vehicle fuel cell sensing system and method. Background technique [0002] Automobiles using internal combustion engines using gasoline or heavy oil as the main fuel have a serious impact on the occurrence of public hazards such as air pollution. Therefore, in recent years, efforts have been made to develop electric vehicles or hybrid vehicles (Hybrid) in order to reduce pollution. [0003] Among electric vehicles, a hydrogen fuel cell electric vehicle (FCEV: Fuel Cell Electric Vehicle) is driven by a fuel cell stack configured by connecting a plurality of fuel cell units in series. [0004] In the case of a fuel cell stack, one cell constituting the fuel cell stack has an output voltage of up to 1V, and the total output voltage can be adjusted according to the number of fuel cell cells. [0005] In order to adjust the power production amount of such a fuel cell stack, the inflow amounts of hydrogen and oxygen are adjusted....
