摘　　要：Large-scale applications of fuel-cell vehicles(FCVs)are of vital importance to reduce emissions of greenhouse gases in the transportation sector,especially in the heavy-duty and long-distance scenarios.Efficient fuelling for the on-board gaseous hydrogen cylinders of an FCV is essential to achieve a fuelling experience that is comparable to that of traditional fossil-fuel-powered vehicles.However,the heating effect during refuelling leads to potential safety issues when the hydrogen temperature in the cylinder exceeds 85℃.Therefore,fuelling protocols are critical to ensure the efficiency and safety of the hydrogen mobility infrastructure.In this paper,the fuelling protocols for FCV vans and buses with type III cylinders were developed and the pre-cooling temperatures were optimized to minimize the energy consumption.Their performance was demonstrated with a 35-MPa hydrogen fuelling station.We found that FCV vans and buses can be safely refuelled in 3 or 5 minutes at a minimum,respectively,demonstrating a fuelling experience that is similar to that of traditional vehicles.
