Özet

In this study, a small portable borohydride fuel cell/ Li-ion battery hybrid system has been developed. The system consists of a single portable direct borohydride/peroxide fuel cell (DBPFC), Li-ion battery and power management unit (PMU). The battery has been used as a primary power sources and discharged at constant load. When its state of charge has reduced, the DBPFC has charged the battery and has powered the load simultaneously. A DC-DC Boost converter has been used as a PMU. The DBPFC has generated the energy of 20.7 mWh while Li-ion battery has consumed the energy of 5.9 mWh. Total efficiency of the DBPFC-Li-ion battery hybrid system has been calculated as 28.5%.
