Fuel cell electric tractor-trailers: technology overview and fuel economy

This study analyzes the application of fuel cells in long-haul tractor-trailers, including technology trends for powertrain architecture, fuel cell units, and hydrogen storage. In addition, it quantifies the hydrogen consumption of fuel cell tractor-trailers under typical mission profiles and operating conditions in Europe and compares the payload and energy efficiency of fuel cell, battery-electric, and diesel technologies.
