Modeling of PEM Fuel Cell Based Power Generation System

Abstract: The rising cost of electricity and environmental concerns have driven research in the renewable energy resources such as wind energy, PV modules and fuel cells etc. Power generation using fuel cell (FC) is getting attention day by day .In fuel cell electrochemical reaction takes place to generate electricity in which water is formed due to oxygen and hydrogen reaction . Advantage of fuel cell is that it emits less CO2. Fuel cell types are generally classified according to the electrolyte nature they use. In this paper, modeling and Simulation of PEM (proton exchange membrane) FC stack is carried out in Matlab/Simulink environment. The output of FC stack model is connected to step-up boost converter, single phase H bridge inverter using the Sim Power Systems of Matlab to get an AC output. Keywords: Renewable Energy, Fuel Cell, Boost Converter, single phase H Bridge Inverter.
