Comparison of Controllers used in Fuel Cell for Power Conditioning

— Fuel Cell (FC) is one of the most promising alternative sources of energy as it is pollution free andgives better power density than other renewable sources. As it does not depend on the weather conditions it isvery useful source of energy. In this paper, performance of evaluation of different controllers used inmathematical expression and modelling of 500W BCS Stack is developed with some important characteristics.Power conditioning unit is connected to get useful voltage from FC. Power conditioning unit consists of Boostconverter to raise the DC voltage of FC, and inverter is used to convert DC voltage into AC voltage. Twotypes of control schemes are employed to control the duty cycle of boost converter, which are PI controllerand Fuzzy logic controller. Outputs of both controllers are comparatively investigated with important results
