5. Requirement and Availability of Scarce Metals for Fuel-Cell and Battery Electric Vehicles
Abstract : Battery and fuel-cell electric vehicles (EVs) are considered as a means to meet some of the environmental and resource challenges of todays road vehicle system. EVs have the potential for zero tailpipe emissions as well as an energy efficiency higher than internal combustion engine vehicles and they can be flexible concerning primary energy source. READ MORE
