Modeling and Performance Analysis of a Closed Loop PEMFC in Small Scale Stand Alone DC System

Minimizing the emission of greenhouse gases attained significant concern during last century. Eco-friendly energy extraction has been a matter of great concern due to the finite and polluting nature of fossil fuel-based resources. In view of this, fuel cell possesses an important part. A fuel cell generally converts chemical energy embedded within fuel into electricity without any combustion as well as through more efficient way. With the advancement in polymer technology, different fuel cells have been fabricated and proton exchange membrane fuel cell (PEMFC) has found efficient in most of the applications now-a-days. In this study, the objective was to analyze the performance of a PEM fuel cell in small scale DC system using a boost converter. The converter is actuated by a Fuzzy logic controller (FLC). The simulation was done in MATLAB/Simulink environment. Such a system can be used to implement small DC charging stations in view of charging electric vehicles.
