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%. © The Electrochemical Society. © 2013 Elsevier B.V., All rights reserved.eninfo:eu-repo/semantics/closedAccessBattery hybrid systemsBorohydride fuel cellsDC-DC boost convertersLi-ion batteriesPower management unitPower management units (PMU)Primary power sourcesTotal efficiencyCharging (batteries)Energy managementHybrid systemsLithiumLithium batteriesConference Object10.1149/05101.0273ecst5112732792-s2.0-84885664458N/A
