The increasing global demand for fossil fuels, which are depleting, calls for
alternative energy sources with efficient and environmentally friendly technologies such as
Proton Exchange Membrane Fuel Cell (PEMFC). This research aims to model and analyze
the effect of hydrogen and oxygen flow rates on the performance of PEMFC using
Computational Fluid Dynamics (CFD) simulation. The flow rates were varied between 0.5,
1, 1.5, and 2.5 L/min for both hydrogen and oxygen. The simulation results show the output
power for each combination, allowing identification of the optimum flow rates for maximum
power output. Validation with previous studies resulted in an acceptable error margin of
0.74%, confirming the model accuracy. The results demonstrate that increasing the flow rate
generally increases the fuel cell’s output power until reaching an optimum point.
