The PEM Fuel Cell System with DC/DC Boost Converter: Design, Modeling and Simulation
نویسندگان
چکیده
The fuel cells are considered as one of the most promising devices for standalone/grid connected distributed generations (DGs) due to its cleanliness, modularity and higher potential capability. The barriers in the widespread use of fuel cells are their slow response for sudden load changes and higher installation cost. In this paper a simulation study of dynamic behavior of Nexa 1.2kW PEM fuel cell with DC/DC boost converter is carried out for compact design of PCU. The necessity for the requirement of boost converter compared with cascaded two stack fuel cell model is also addressed. Moreover the performance of the simple DC/DC boost converter as power modulator for Nexa 1.2kW PEM fuel cell model is analyzed for varying loads in order to control power flow for enhanced performance.
