"Fuel cell technology offers the potential to excel today’s motive power techniques in terms of environmental compatibility, consumer’s profit, costs of maintenance and efficiency. The key question is economy. It will be decided by the costs of fuel cell systems if they will be used as power generator for future electric vehicles. The objective is to lower the fuel cell system cost on a mass production scale to the range of $ 100 to $ 150 per kW." (Quoted from paper)
