The concept of hydrogen fuel cells was invented in 1839 by Sir William Grove. BOC's director of sustainable energy, John Carolin, said:"The lessons from this and other projects will show that hydrogen fuel cell-powered vehicles could be a practical, attractive and a viable economic alternative to diesel- or petrol-fuelled vehicles."

BOC公司可再生能源部的主管约翰·卡罗林表示，&通过这辆汽车及其它同类项目所得到的经验将会告诉世人，将氢燃料电池做为汽车的动力来源这一想法是可以变为现实且颇具吸引力的，从经济角度来看，这种车也完全可以替代那些以汽油或柴油做动力的汽车&。

The invention is characterised in that the gaseous fuel containing hydrogen or consisting of hydrogen is fed into the swirl generator (1) largely axially and/or coaxially to the burner axis, forming a fuel flow, with a largely spatially defined flow form (9) which is maintained inside the burner and opens up in the region of the burner outlet.

Hitherto mankind has relied on fossil fuel for a major part of its energy supply. Obviously the reserve of fossil fuel is by no means unlimited and will eventually be exhausted after decades. Hence, so far as long-term viewpoint is concerned, it is of importance to utilize the abundant and elean solar energy as an alternative energy source. Stimulated by this objective, studies on the preparation of suitable thin semiconductor films of larger size using simpler methods have attracted increasing interests.

Through comparison of energy inputs in corn fuel ethanol life cycle,fossil energy inputs of corn production and ethanol conversion processes were identified as the most important,and therefore nitrogen fertilizer,electivity and diesel used in corn farming and energy consumption of distillation and dehydration process in ethanol production could be known as the most influential factors for the energy benefit of corn fuel ethanol.

但是玉米燃料乙醇从原料的生产、乙醇的转化，一直到被燃耗的整个生命周期中的多个阶段需要直接或间接地消耗矿物能源，因而，虽然玉米燃料乙醇是可再生能源，然而是否具有可持续性及可持续性的大小则取决于其燃耗中所产生的能量与燃料乙醇整个生命周期中所消耗的能量相比是否有盈余及盈余的大小。20世纪70年代中期，玉米燃料乙醇的能量平衡问题研究首次在美国出现[2，3]，当时乙醇替代汽油的能量效益的有关研究指
