This paper investigates the performance of fuel cell hybrid buses (FCBs) in the project "New Energy Vehicles for Olympic", with the energy system and vehicle economy studied based on the key performance parameters from the operation. Statistical analyses show that, for the public transportation road condition, the FCBs contribute most of the drive mileage at mid-and high-speeds while consuming most of the total fuel at low-speeds and the idling state. The fuel cell systems supply energy with high average efficiencies of 40%-50%, with the homemade FCBs having fuel economy performance of about 27%, better than that of the conventional diesel city bus. The auxiliary power varies with different seasons of a year, with the auxiliary power consumption fluctuating by 10%-18% of the total energy due to the air-conditioning. The FCB energy flow diagrams of brake energy regeneration systems show recycled brake energy of 7%-8% of the total energy consumption.
