Fuel cell plug-in hybrids: Long-distance emobility with batteries and fuel cells

摘要

Fuel cell plug-in hybrids combine the advantages of batteries and fuel cells - short driving distances are covered in battery electric operation, a downsized, low cost fuel cell system enables long distance emission free mobility and short refuelling times. A consortium of industry and R&D partners developed a compact 30 kW fuel cell system and integrated it into a battery electric vehicle as a functional demonstrator. The paper focuses on the development of the automotive stack that features metallic bipolar plates with an active area of 300 cm~2 and achieves high performances of more than 1.0 W/cm~2 without cathode humidification.
