In the study, we proposed a new formula forthe hydrogen consumption of fuel cell under non-constant current behavior. Weused supercapacitors as auxiliary energy source to form a hybrid system andchange the current behavior of the fuel cell. We performed hybrid system testsfor different supercapacitor values. We extracted the fuel cell current,voltage, hydrogen consumption for each configuration. We compared the measuredvalues and expected values from known equations. We see that, results fromhydrogen consumption equations does not match the hybrid system hydrogenconsumption. Finally, we proposed a new formula for hydrogen consumptionincluding the current gradient and current peak value for hybrid systems.
