Conclusions In a fuel-cell-based direct-hybrid system, a fuel cell and a battery are connected in parallel without a DC/DC converter. The voltage levels in the system are therefore directly determined by the choice and design of the fuel cell and battery.
Can a fuel cell and battery direct hybrid system work without DC/DC converters?
A fuel cell and battery direct hybrid system concept without DC/DC converters was proposed. The system concept was validated by measurements using an electric system composed of a low-temperature PEFC stack and Li–FePO 4 battery blocks. The measurements showed good system efficiency and good response to dynamic load requests.
How many fuel cells can be used in a direct hybrid system?
U BA0, is in the range of U FC1 < U BA0 < U FC0 and the minimum voltage at maximum current, U BA1, is close to U FC1 as U BA1 ≈ U FC1. For example, if we decide to use the 42-cell fuel cell stack ( Fig. 14 ), we can select from 7 to 10 cells for the battery to create a feasible direct hybrid system.
How does a direct-hybrid fuel cell work?
In a direct-hybrid, the fuel cell and the battery are connected to a powertrain, as shown schematically in Figure 1, without the use of a DC/DC converter. Diodes are installed to prevent the current from flowing backwards into the fuel cell or the battery.
What is a direct hybrid system?
The direct hybrid system is composed of a H 2 /Air PEFC stack and a battery pack. The most important aspect of the system is that the DC/DC converter is replaced by two diodes, each connected in serial with one of the power sources. This layout enables the fuel cell to be directly connected to the battery pack in parallel.
