“…However, the output voltage of the DC/DC converter needs to be carefully determined according to the characteristics of both power sources. Aso et al [10] showed a passive hybrid configuration developed by Toyota Motor Corporation; however, the dynamic behavior of each power source was not reported. Bernard et al [11] developed a model to simulate a passive hybrid power system with an H 2 /O 2 fuel cell system.…”

A laboratory-scale passive hybrid power system for transportation applications is constructed and tested in this study. The hybrid power system consists of a fuel cell stack connected with a diode, a lithium-ion battery pack connected with a DC/DC power converter and another diode. The power converter is employed to regulate the output voltage of the battery pack. The dynamic responses of current and voltage of the stack to the start-up and acceleration of the load are experimentally investigated at two different selected output voltages of the DC/DC converter in the battery line. The power sharing of each power source and efficiency are also analyzed and discussed. Experimental results show that the battery can compensate for the shortage of supplied power for the load demand during the start-up and acceleration. The lowest operating voltage of the fuel cell stack is limited by the regulated output voltage of the DC/DC converter. The major power loss in the hybrid power system is attributed to the diodes. The power train efficiency can be improved by lowering the ratio of forward voltage drop of the diode to the operating voltage of the fuel cell stack.

The authors have proposed and made a hydrogen generation system for fuel cell electric vehicles (FCEVs) and fuel cell hybrid electric vehicles (FCHEVs). The system which is called as STEP (Sodium TEtrahydroborate Power) system generates large amount of hydrogen by hydrolysis of powdery sodium borohydride (NaBH4). In this paper, The authors constructed a prototype FCEV with STEP system, and the effectiveness of the proposed system was verified by comparison with a conventional system in experiment. Two driving patterns, which simulate the driving situations of rapid acceleration, traffic jam and constant low speed, were used in the experiment to verify the effectiveness of a FCEV with STEP system. And, the STEP system used in hydrogen pressure control is still unstable during acceleration; however, the transient characteristics of the FC output power in both system were almost same. As a result, it was understood that the proposed system had ability of hydrogen supply system as well as a conventional system.

This paper presents a comparison of two potential softswitching bi-directional high-frequency transformer isolated voltage-fed and current-fed dc/dc converters for fuel cell vehicle application. The given comparison and discussion is suitable for a front-end dc/dc converter for a fuel cell inverter. The circulating and peak currents, components' ratings, size, losses, and efficiency are compared. Current-fed converter has been justified due to its merits over voltage-fed converter for the given applications. Experimental results of the current-fed converter have been illustrated. Switching losses are reduced a lot due to soft-switching of primary and secondary devices and higher efficiency. It allows high switching frequency operation, which results in compact and low cost system.
