Article in Guide for the 2005 Geneva Motor Show The fuel cell produces an electric current using hy­drogen. It is by no means new, having been used in space exploration since the 1960s. Until now, its use in the car was always difficult to imagine be­cause of its sheer bulk, weight and cost. Thanks to improvements contributed in particu­lar by Ballard Power Systems, a fuel cell can now fit into a normal-sized private car. Nevertheless, the cost is still ten times greater than that of an internal combustion engine. There is another problem: hydrogen is not an immediately available source of energy and needs an intermediary production process. Thus, in order for the use of hydrogen to be neutral as far as CO2 emissions are concerned, it would be necessary for it to be produced on a large scale from solar, wind or hydraulic energy, which it not possible at the moment. In addition, according to studies car­ried out in the United States, the necessary infra­structure to produce and distribute the hydrogen required for just 10% of its fuel consumption would cost close to 100 billion dollars. retour au CUEPE Informationen zu Wasserstoff als Energieträger.
