新浪科技讯 北京时间3月5日消息，据国外媒体报道，日前，瑞士日内瓦车展上亮相一款“零排放”的高速跑车，这款英国摩根公司推出的名为“生命之车”(Lifecar)跑车最高可达到100英里/小时的速度，是世界上第一款绿色跑车。
它采用氢动力、基于摩根Aero-8跑车的设计，运行时产生很小的噪音，仅在排气装置上形成非常少的水蒸汽。“生命之车”是一款轻重量型跑车，安装了高级氢燃料电池和能量存储系统，一罐氢燃料电池可运行250英里(400公里)。它是由英国大学和公司联合技术设计的。顶尖跑车制造商摩根公司发言人马修·帕金(Matthew Parkin)告诉英国BBC记者说，“这款跑车可在短短7秒内启动加速至60英里/小时。但是精确的加速度尚不能确定，在完成第一次试车后才能知道。”
零排放、智能动力
为时近3年的“生命之车”建造项目共投资190万英镑，其中部分资金是由英国政府投资的。该跑车的氢燃料电池是由英国奎奈蒂克(QinetiQ)公司研制，该公司的伊恩·惠廷(Ian Whiting)解释称，“如果你采用一个传统的内燃发动机来代换一个氢燃料电池，那么这个燃料电池是非常大的，而且效率并不高。”“生命之车”采用的氢燃料电池是22千瓦，大约是传统内燃发动机的五分之一，但却可能够满足人们的驾驶需要。
当它需要加速攀升一个斜坡时，驾驶者可从跑车中部下方的超电容阵列罐获得附加的动力。惠廷解释称，它就像一个电池，不会完全存储大量的能量，这些能量注入和消耗都很快。汽车内置的再生制动系统可实现充电，当汽车缓慢运行时将把汽车的动力能量转换成为有用的发动机电能。普通的再生制造系统可恢复10%的能量，而“生命之车”可恢复至50%的能量。

安静无噪音、重量仅700公斤
“生命之车”高速90英里/小时状况下可行驶250英里。帕金解释说，“在最后设计的几天中，减轻了车身的重量使该跑车整体功效大大提升。它采用了一个铝制底盘，包括座位在内的内部结构采用轻重量的木制材料。它并没有像立体声音箱、中央锁定等‘奢侈’的功能，甚至许多现代汽车中配备的气袋也没有。‘生命之车’的重量已降至700公斤。”
此外，该车还省去了变速箱，氢燃料电池将产生很小的噪音，而传统的发动机却时常会发出“咆哮”的声音。帕金称，我们必须带上耳机才能听到油门踏板的噪音。
目前，其他汽车制造商也展示了多款氢动力跑车，但是许多车型已改变了现有模型或改成同时采用汽油的复合型。比如：日本马自达亮相其RX-8 Hydrogen RE型跑车，它采用氢燃料转子引擎，具有双重燃料系统。此外，日本本田将于2009年推出一款名为CR-Z油电混合动力系统的概念车。
道路崎岖和补给是大麻烦
然而，道路的崎岖不平对于氢燃料汽车是一个大麻烦，批判人士指出，使用大量的电能分离水从而产生氢，目前这些电能来自于矿物燃烧，因此对于环境保护不利。此外，很少有对氢动力汽车进行补给的基础设施。
惠廷指出，在许多城市氢动力公交车可以返回中央车站进行补给。但是私人氢动力汽车的补给站却仍需要很长时间才能完善。

Here Comes the World's First Green Car

Sina Technology – March 5. According to foreign media reports, a ‘zero emission’ high speed sports car was showcased at the Geneva Motor Show, Switzerland. This model introduced by a British car company, Morgan Motor, is the first green sports car in the world. It is named ‘Life car’. It can reach a maximum speed of 100 miles per hour.
The ‘Life car’ is based on the Morgan Aero-8 sports car design and uses hydrogen as the fuel source. It generates a very low volume of noise when it is running, and a very small amount of water vapor in the exhaust device. ‘Life car’ is a type of light-weighted sports car with a high hydrogen fuel cell and energy storage system installed. A can of hydrogen fuel cell can last for 250 miles (400 kilometers). It was designed by a British university and Morgan Motor Company. The spokesman of top sports car manufacturer Morgan Motor, Matthew Parkin, told a journalist from BBC, “it can accelerate from 0 to 60 miles per hour within seven seconds. However, the exact speed will not be confirmed until after finishing the first test.”
Zero emission, intelligent power
It took almost three years and a total investment of 1.9 million pounds to complete the ‘Life car’ project, and some part of investment was funded by the British government. The hydrogen fuel cell used by the car was developed by QinetiQ. Ian Whiting from QinetiQ explained that, “If you replace a hydrogen fuel cell with a conventional internal combustion engine, the fuel cell will be really big and has low efficiency. However, the hydrogen fuel cell adopted by ‘Life car’ generates 22 kilowatts of electricity, and the size is about one fifth of a conventional internal combustion engine. Yet it still can meet the needs of driving”.
When it needs to accelerate up a slope, the driver can receive extra power from the ultra-capacitor underneath the middle of the sports car. QinetiQ explained, it is like a battery which will not store a lot of energy, but both injection and consumption of energy take place very quickly. The internal regenerative braking system can recharge the cell. When a vehicle runs slowly, kinetic energy will be converted into electricity and used by the engine. Ordinary regenerative braking systems can recover 10% of the energy, but ‘Life car’ can recover 50%.
Structure of Life Car
No noise, only weighs 700 kilogram
‘Life car’ can run for 250 miles at a speed of 90 miles per hour. Mr. Parkin explains, “In the last few days of designing, reduction of the body weight dramatically improved the whole efficiency of the car. It has an aluminum chassis, and light weighted wooden material was used for internal structures including the seats. It does not have ‘luxurious’ functions like stereo speakers and central locking etc, or even air bags which are equipped in modern vehicles. The weight of ‘Life car’ has been lowered to 700 kilograms.”
Furthermore, the car does not have a gear box. The hydrogen fuel cell only generates a very low volume of noise, in contrast the conventional engine is often very loud. Mr. Parkin claimed that we must wear earphones to hear the noise of the accelerator pedal.
Recently other vehicle manufacturers also showcased a few models of hydrogen fuel cell sports car, but many of them have changed current models or changed into dual fuel system. Honda Japan will also introduce a hybrid power system concept car named CR-Z in 2009.
Bumpy roads and supply are a concern.
However, bumpy roads for hydrogen fuel vehicles are a problem. Criticism suggests that massive use of electricity could produce hydrogen out of water. Furthermore the electronic current comes from burning minerals, so it does not benefit the environment. Moreover, there are only a few fuel stations for hydrogen fuel vehicles.
QinetiQ pointed out that hydrogen buses can be refilled in central bus terminals in a lot of cities. However, private hydrogen vehicles supply stations need a long time to be improved.
