%0 Journal Article %T Design of a PEM Fuel Cell Simulator Based on DC-DC Buck Converter %A Georgi Georgievski %A Goce L. Arsov %J Electronics %D 2010 %I University of Banja Luka %X Modeling of fuel cells is getting more and more important as power fuel cell stacks being available and have to be integrated into real power systems. This paper presents a novel circuit simulator for a PEM fuel cell that can be used to design fuel cell based systems. The simulator is consisted of a DC-DC buck converter driven by PIC 16F877 microcontroller. The proposed circuit can be used in design and analysis of fuel cell power systems. %K PEM fuel cell %K Modeling %K Design %K Simulation %K Pulse width modulation (PWM) %U http://electronics.etfbl.net/journal/El_2010_1_Complete.pdf
