Towards Sustainable Mobility

摘要

Global transport demand is expected to increase due to the combined influences of population growth and economic development. to ensure that CO_2 - neutral fuels can provide for an increasing fraction of this demand, both demand side measures and advances in vehicle technology are required. Specific fuel consumption may be lowered by decreasing the energy demand at the wheel (lighter vehicles with lower air and rolling resistance), by using highly efficient converters such as fuel cells, and by advanced systems design that allows for the recuperation of braking energy. Low temperature polymer electrolyte fuel cells combined with regenerative electricity storage in supercapacitors represent a particularly promising option, as they combine an attractive cruising range with ultra-low emissions.
