Abstract
Fuel cells, on account of their properties like clean, efficient and reliable source, are emerging as an attractive power source. As the demand for various applications like remote generation, back up generation and distributed generation increases the use of fuel cell is spreading widely, accordingly, their penetration in to the commercial market. Fuel cell is expected to play an important role in future power generation. The purpose of this work is to present the overview of power conditioning unit (PCU) for non-conventional energy source. It highlights the SOFC fuel cell system in which fuel cell stack is connected to other building blocks like BOP (balance of plant) equipment, PCU and load. The purpose of BOP is to manage the reactants and products of fuel cell. The dc power generated by SOFC fuel cell is converted to ac power by PWM inverter. The present work also highlights the performance analysis of PCU with PI controller since simulation provides the real time environment, which solves many problems which occur during actual hardware implementation; therefore the above said system is simulated in simulink environment. The variation of voltage and current of fuel cell stack and dc bus, utilization of fuel, stack efficiency and voltage and current across load are shown in different scopes.
