The concept of a passive hybrid system consisting of fuel cell stacks, Li-ion battery packs, and two diodes was tested. The diodes take the place of the DC/DC converter that is usually used to align fuel cell and battery voltages, thereby directly connecting the fuel cell and the battery. Prototype equipment was built for collecting characteristic data on the static and dynamic behavior of the hybrid system. The measurement results indicate that increasing the operation efficiency and simplifying the system were possible by applying the direct hybridization concept. The dynamic behavior results showed an interesting combination of output signals from the fuel cell stack and the battery pack. The quick response of the battery output complete...
