Abstract
A method and a system for controlling hydrogen supply for a fuel cell are provided. The method includes calculating a target hydrogen supply pressure, which is a target pressure value of hydrogen supplied to a fuel cell stack based on a required output. A fuel supply valve (FSV) duty is then adjusted based on the calculated target hydrogen supply pressure and modes are determined based on the FSV duty or actual hydrogen supply pressure measurements of a sensor. A hydrogen supply pressure measurement is calculated according to each of the determined modes and the FSV duty is corrected based on the calculated target hydrogen supply pressure and the hydrogen supply pressure measurement.
