Abstract
An apparatus and method for controlling hydrogen purging are provided. The hydrogen purging control apparatus includes a purge valve that is disposed at an outlet on an anode side of a fuel cell stack and is configured to adjust an amount of emission of hydrogen containing impurities. Additionally, a controller is configured to adjust an opening and closing cycle of the purge valve based on a required output or an output current of the fuel cell stack.
