If promoting the use of fuel cell, platinum will be exhausted even earlier than oil resources.? 陶瓷三元催化排氣凈化器生命周期中的主要環(huán)境影響發(fā)生在鉑元素的開采、提煉和使用階段，而且與使用階段減少的汽車尾氣污染相差不大。從生命周期角度來看，汽車排氣凈化器僅是一個 “轉(zhuǎn)化器 ”，把一個地方的環(huán)境污染轉(zhuǎn)移到另一個地方 ；? In the life cycle the main environmental impacts of Ceramics 3way catalytic exhaust purification equipment are platinum mining, refining and using stage, and these environment pollutions are equivalent to those which this equipment could reduce from emitting directly. From a lifecycle perspective, automobile exhaust purification is just a “transferor, which transfers a local environmental pollution to another place。? 電動汽車的生命周期成本較高。當電動汽車的制造成本降低到$100/kWh，充電次數(shù)達到 1200次或使用壽命達到 12年，能量 /重量達到 100 Wh/kg 時，電動汽車才具有成本競爭性。用煤電和鉛酸電池技術(shù)支撐的電動車是 “骯臟的 ”。? The costs of electric vehicle in the whole lifecycle is high. Unless electric vehicles manufacturing cost is reduced to $ 100 / kWh, the recharge times rises to 1,200, or using 12 years, energy / weight to 100 Wh / kg, electric cars bee petitive in the vehicle market.
