Today, Fuel Cell Electric Vehicles (FCEV) have substantial challenges regarding reliability and control. Multi-Stack fuel cell (MSFC) technology provides an innovative method for tackling some of these issues, particularly reliability. This paper reviews the literature on electrical association architecture studies on MSFCs with converters. An analytical study has also been presented to choose the optimum association architecture and the best suitable boost converter topology promising in FCEV applications regarding lower input current ripple, reduced inductance size, improved efficiency and higher reliability. According to the findings, the interleaved boost converter (IBC) topology and parallel association architecture of each fuel cell with a converter is the best choice for such applications.A control strategy of an FC stack using a non-isolated 4-Phases DC/DC boost converter has been presented and validated. This control is ensured by hybrid duel loop control, including voltage and rapid current loops with linear PI controllers. The simulation results demonstrated the converter's and control strategy's high efficiency and functionality.
