Fuel cell power conditioning unit for standalone application with real time validation
In recent era, fuel cells are emerging as better alternative to wind and solar based energy sources due to its reliability and high efficiency. Polymer Electrolyte Membrane Fuel Cell (PEMFC) is widely used in various applications due to low operating temperature and high energy density. On the other side low and unregulated stack voltage demands PEMFC integration with suitable power conditioning unit. However, the use of actual fuel cell power conditioning unit in design and testing for research is expensive. Any failure may lead to damage of source or power circuit. In this regard, the present work aims at developing a soft-computing model of PEMFC. Also, a DC-DC converter is designed to stepup the stack voltage. A classical PI controller is implemented to regulate the PEMFC fed power conditioning units for resistive loads. The proposed system is implemented is Hardware-In-the-Loop (HIL) using OPAL-RT's OP5600 Real Time Digital Simulator (RTDS). (C) 2018 Hydrogen Energy Publications LLC. Published by Elsevier Ltd.
