The present invention is a fuel cell as a stack on the pressure swing control method for a fuel electrode, and more particularly, comprises a reference pressure difference from two points preset on the reference output and the anode close to the mapping in accordance with the operating pressure of the fuel cell system from the electronic controller a first step to identify the operation information; Fuel cell by comparing the output with the reference output of the system, a second step that is lower than the reference output is output so that the control target pressure of the pressure fluctuations within the fuel electrode in the electronic controller; And to compare the measured differential pressure and the reference differential pressure at the two points, If the measured pressure differential is less than the reference pressure difference a third step of controlling to decrease the purge valve operating cycle from said electronic controller; by including a fuel cell system It can be obtained in a high efficiency in the entire operating region, improving the fuel efficiency by efficiently controlling the purge valve operating cycle, and can improve the durability of the fuel cell stack.
