Abstract—This paper presents the simulation of a dynamic model of PEM (Proton Exchange Membrane) fuel cell in Matlab and Labview which provides an easy to use and understand simulator with GUI. The open circuit output voltage, activation losses, ohmic losses, concentration losses and temperature dynamics are modeled and analyzed for change in the input parameters. Power conditioning unit for the cell are modeled and control strategy is implemented for them. The simulation results are then scaled down for hardware implementation. II. PEM FUEL CELL MODELING The individual components of the fuel cell system the various governing laws for each of these components and their interaction with each other make the fuel cell system very complex and sophisticated. Thus, to avoid complications in the analysis, the model is based on certain assumptions like ideal behavior of gases, uniform distribution of species and no temperature and pressure variations for the system. The PEM fuel cell is an electrochemical device in which the oxidation of hydrogen occurring at anode liberates free electrons and hydrogen ions which move through the external circuit and membrane respectively. The reduction of oxygen at cathode utilizes the protons and electrons reaching it to form water. Index Terms—PEM fuel cell, boost converter, labview I. INTRODUCTION The increasing .
