Now-a-days, electrical energy is the most important and powerful one used as large energy level. Fuel cell energy is used as alternate and non-harmful energy source used in many applications. For this generation an electrolyser is used to produce hydrogen through electrolysis. Due to this electrolysis H2 gas is produced and stored. This H2 gas is send to fuel cell and produce electricity whenever it is needed. This electrolyser is connected to an DC bus via a DC-DC boost converter. This boost converter gives a constant voltage to electrolyser even if there is any variation in DC bus voltage. A buck/boost converter is used in between fuel cell and DC bus.
