The conventional energy resources present in nature are limited and exhaustible, if it would be used with the rate at which it is being used in today's era then it will be vanished up. So we have to go with the alternative i.e.it is necessary to promote nonconventional energy resources as main source of energy. Fuel cell power generation systems (FCPGS) are going to play an important role for future applications. Fuel cells convert chemical energy into electrical energy. Output voltage of fuel cell is very small, almost less than 1 volt, so number of fuel cell connected in series i.e. stacked in order to increase its voltage level. In this paper the authors has studied the voltage current and power voltage characteristics of proton exchange membrane fuel cell (PEMFC). Low voltage output of fuel cell stack (FCS) is connected to a step up chopper which boost the voltage level. The output of the chopper is fed to a DC load. The results are presented in tabular form as well as waveforms. All the studies are simulation based, and the simulations are performed in MATLAB/Simulink.
