The purpose of this research is to study the performance of hydrogen fuel cell to study different fuel flow rate and different concentration to obtain the optimum performance of the cell. First, design a hydrogen fuel cell model, second simulate cell performance toward hydrogen fuel flow rates of 6, 18, and 30 mL/min and fuel concentrations of 50 mol/m3. Subsequently, we obtained the characteristics of voltage-electric current density and power density-electric current density per stack of fuel cell. The research of this hydrogen fuel cell obtained the power density optimum of 0.0471 mW/cm2 at a cell current density of 0.135 mA/cm2 and a cell voltage of 0.35 V. The greater the load the greater the time used by the battery for instant loads. The average time when the load is small is 10 W with a time of 240 hours and the fastest time when a large load is 400 watts with a time of 6 hours. Decreasing battery discharge time to the same load due to the completion of power losses in each device or circuit that produces the power generated by the battery does not reach the maximum load.
