“…The main objective of the control strategies is to regulate the DC bus voltage with the FC as the primary power source (Davat et al, 2009). However, fuel cell performances (efficiency, degradation, aging effects) are influenced by many environmental and application constraints (Wahdame et al, 2008).…”

The problem of converters coordination of a fuel cell system involving a hydrogen fuel cell with supercapacitors for applications with high instantaneous dynamic power is addressed in this paper. The problem is solved by using a non-linear controller based on passivity. The controller design is based on the interconnection and damping assignment approach, where the proof of the local system stability of the whole closed-loop system is shown. Simulation and experimental results on a reduced scale system prove the feasibility of the proposed approach for a real electrical vehicle.

“…The parallel structures with only one converter (Azib et al, 2010;Davat et al, 2009) or two converters (Davat et al, 2009) can fully respect the mentioned requirements. This paper is dedicated to the study of the structure with two converters as shown in Fig.…”

In transport application, long high power PEM fuel cell stacks could suffer from voltage discrepancy between cells due to severe constraints or appearance of localized faults in case of bad water management, moreover the output power of the stack is limited by the weakest group of cells. This article proposes a three-part segmented fuel cell associated with an isolated four-source DC/DC converter which makes possible a power sharing between the fuel cell segments according to their state-of-health. This topology allows an enhanced utilization of the stack as well as fault tolerance. ZVS operation is achieved to improve global converter efficiency.

“…In those cases, many hybrid architectures have been suggested using ultra-capacitor banks or battery packs. For such applications, power demand on the FC can be limited to a low-frequency bandwidth around 0.1 Hz [13], [14] through the simultaneous use of an auxiliary storage electric source dedicated to high transient power. This technique called hybrid power source has, for example, been proposed for automotive applications in which power demand fluctuates suddenly because of speed changes or inclination modifications [17], [18].…”
