摘要：	Hybridizing fuel cell (FC) vehicles with energy storage (ES) could result in improved performance and fuel economy, and reduced cost. We analyzed ES needs for a light mid-size car with a hydrogen FC as the main power source. We used the ADVISOR vehicle simulator with its ES and FC components for the analysis, and tested several different drive cycles, FC characteristics, and different ES to FC power ratios. We assumed that at idle, the fuel cell is not shut down and consumes enough hydrogen fuel to sustain itself without generating net power. Regen braking and vehicle deceleration were the major sources of charging for the ES for later use. The optimum fuel economy occurs when peak FC efficiency is around the average power demand for a particular drive cycle. There is positive benefit to downsizing the FC if the peak efficiency is shifted toward the typical power operating point. We proposed an ES system with 25 kW discharge (12 seconds), 20 kW charge (5 seconds) with available energy of 250 Wh and a 56 kW FC for the light mid-size car. The fuel consumption of this hybridized case was about 30%less than fuel cell only case.
