Polymer Electrolyte Membrane Fuel Cell (PEMFC) is a clean energy technology that has great potential as an alternative energy source. This study aims to analyze the effect of variations in the diameter of the oxygen input hole in a double cell PEMFC on its power density and efficiency. The diameter variations used are 4 mm, 6 mm, and 8 mm. Tests were carried out by observing the relationship between voltage, current, current density, power density and efficiency. The results of the analysis show that increasing the diameter of the oxygen input hole can improve the performance of the PEMFC to reach optimum conditions. A diameter of 4 mm produces the highest current, current density, and power density compared to other variations. Thus, the diameter of the oxygen input hole of 4 mm is stated as the most optimal condition to improve the performance of the double cell PEMFC.
