Systems Integration and Performance Issues in a Fuel Cell Hybrid Electric Vehicle 2000-01-0376

The Hybrid Electric Vehicle Team of Virginia Tech (HEVT) has integrated a proton exchange membrane fuel cell as the auxiliary power unit of a series hybrid design to produce a highly efficient zero-emission vehicle. A 1997 Chevrolet Lumina sedan, renamed ANIMUL H2, carries this advanced powertrain, using an efficient AC induction drivetrain, regenerative braking, compressed hydrogen fuel storage, and an advance lead-acid battery pack for peak power load leveling. The fuel cell supplies the average power demand and to sustain the battery pack state-of-charge within a 40-80% window. To optimize system efficiency, a load-following strategy controls the fuel cell power level. The vehicle weighed 2000kg (4400lb) and achieved a combined city/highway fuel economy of 9L/100 km or 26 mpgge (miles per gallon gasoline equivalent).
