In this final project, Proton Exchange Membrane Fuel Cell (PEMFC) Modeling and Simulation Study are presented using MATLAB/SIMULINK software environments. The model main characteristic are validated by experimental data taken from reference[5] at an Avista Labs SR-12 500-W PEMFC stacks. Simulation results show that the PEMFC model characteristics is quite agree with experimental data results. However, the PEMFC model graph is have a lower slope than experimental data graph because ohmic voltage drop value in the model is lower than the real value. So, empirical approach is needed for obtain ohmic voltage drop more precisely. After correction were made,PEMFC model results are better and more agree to the experimental data. Another simulation was made to see start-up response characteristic of a PEMFC model for a constant load. Simulation results show that the voltage response from start-up to steady state has through 0,3 seconds. The value of output voltage drop is mainly influenced by double layer capacitance voltage drop. At start-up temperature response, model temperature will increase very quickly at starting point then goes slowly after 1500 seconds, and at last inclined to be constant after 2500 seconds. The last simulation was a calculation of PEMFC model hydrogen and oxygen cost to generate electricity. Simulation results show that total hydrogen and oxygen cost of PEMFC model are ranging from Rp 3.164,86/kWh to Rp 5.046,60/kWh. <br />
