1、原理不同(tong)

（1）純電動汽車(che)的(de)原理(li)是依靠電池儲備能源，用電機(ji)驅動汽車(che)行駛(shi)。最核心部分就(jiu)是電池、電控、電機(ji)的(de)三電技術。

（2）燃料電(dian)(dian)(dian)(dian)(dian)池(chi)汽車以氫氣為(wei)能(neng)源，工作原理是把(ba)(ba)氫輸入(ru)燃料電(dian)(dian)(dian)(dian)(dian)池(chi)中，氫原子的電(dian)(dian)(dian)(dian)(dian)子被質子交換膜阻隔，通過外電(dian)(dian)(dian)(dian)(dian)路從負極傳(chuan)導到正極，成為(wei)電(dian)(dian)(dian)(dian)(dian)能(neng)驅動電(dian)(dian)(dian)(dian)(dian)動機。區別(bie)于傳(chuan)統的干(gan)電(dian)(dian)(dian)(dian)(dian)池(chi)、蓄電(dian)(dian)(dian)(dian)(dian)池(chi)，普通電(dian)(dian)(dian)(dian)(dian)池(chi)是一(yi)種(zhong)儲能(neng)裝置，是把(ba)(ba)電(dian)(dian)(dian)(dian)(dian)能(neng)貯存起來，需要時再釋放出來；氫燃料電(dian)(dian)(dian)(dian)(dian)池(chi)嚴格地(di)說是一(yi)種(zhong)發(fa)電(dian)(dian)(dian)(dian)(dian)裝置，就像發(fa)電(dian)(dian)(dian)(dian)(dian)廠一(yi)樣，是把(ba)(ba)化(hua)學能(neng)直(zhi)接(jie)轉化(hua)為(wei)電(dian)(dian)(dian)(dian)(dian)能(neng)的電(dian)(dian)(dian)(dian)(dian)化(hua)學發(fa)電(dian)(dian)(dian)(dian)(dian)裝置。

2、續航能力不同

燃(ran)料電(dian)(dian)(dian)池(chi)汽(qi)(qi)車的(de)續(xu)航(hang)(hang)里(li)(li)程(cheng)一般都是(shi)400公里(li)(li)以(yi)上，和傳統的(de)燃(ran)油(you)車非常接近。而對純電(dian)(dian)(dian)動汽(qi)(qi)車來說，更(geng)(geng)(geng)長的(de)續(xu)航(hang)(hang)里(li)(li)程(cheng)意味著(zhu)更(geng)(geng)(geng)重(zhong)更(geng)(geng)(geng)貴的(de)鋰(li)(li)電(dian)(dian)(dian)池(chi)包(bao)。再加(jia)上深度放電(dian)(dian)(dian)會影響鋰(li)(li)電(dian)(dian)(dian)池(chi)壽(shou)命，也就是(shi)不(bu)能像傳統汽(qi)(qi)車那(nei)樣將油(you)用干(gan)再加(jia)滿，所(suo)以(yi)實際續(xu)航(hang)(hang)里(li)(li)程(cheng)比宣稱的(de)還要低不(bu)少。雖然燃(ran)料電(dian)(dian)(dian)池(chi)汽(qi)(qi)車的(de)價格目前(qian)更(geng)(geng)(geng)高，但(dan)從前(qian)景(jing)來說，同(tong)樣續(xu)航(hang)(hang)里(li)(li)程(cheng)的(de)情況下，燃(ran)料電(dian)(dian)(dian)池(chi)汽(qi)(qi)車的(de)成本會低于純電(dian)(dian)(dian)動汽(qi)(qi)車。

3、起步速度不同

燃(ran)料電(dian)池汽(qi)車(che)和純電(dian)動(dong)汽(qi)車(che)兩者之間(jian)的(de)(de)起(qi)步的(de)(de)速(su)度還是有(you)所區別(bie)的(de)(de)，主要(yao)的(de)(de)原因就是燃(ran)料電(dian)池的(de)(de)燃(ran)料在車(che)的(de)(de)儲(chu)存罐當中(zhong)反(fan)應是需要(yao)時(shi)間(jian)的(de)(de)，從(cong)車(che)輛的(de)(de)構(gou)造上面來(lai)說，燃(ran)料車(che)的(de)(de)乘坐空間(jian)并(bing)沒有(you)電(dian)動(dong)汽(qi)車(che)的(de)(de)乘坐空間(jian)舒適，燃(ran)料電(dian)池需要(yao)大的(de)(de)儲(chu)存罐，會占(zhan)據一(yi)定的(de)(de)內部空間(jian)。

4、燃料(liao)/電能補(bu)充(chong)不同

燃料電(dian)池(chi)汽車的加氫是(shi)物(wu)理(li)過程，3分鐘左(zuo)右(you)便可加滿。純電(dian)動汽車的電(dian)池(chi)充(chong)電(dian)是(shi)電(dian)解(jie)(jie)反(fan)應(ying)，充(chong)電(dian)的時候需要(yao)控制否則(ze)會有副反(fan)應(ying)發生，目前(qian)快(kuai)充(chong)是(shi)半個小時充(chong)滿80%，在將(jiang)來(lai)很長一段時間內(nei)比較難提(ti)高充(chong)電(dian)速度。快(kuai)速換電(dian)池(chi)的解(jie)(jie)決(jue)方案受制于電(dian)池(chi)質量、所有權、電(dian)池(chi)型(xing)號等(deng)問題，可能對(dui)于公交車有更多幫助，對(dui)私家乘用車來(lai)說，前(qian)景比較渺茫(mang)。

5、發展前景

根據目前的(de)發展來看(kan)，純電(dian)動汽(qi)車(che)由于(yu)成本更低，在(zai)短時間內相比(bi)氫(qing)燃料電(dian)池(chi)汽(qi)車(che)還是(shi)比(bi)較有(you)優勢的(de)。根據長遠來看(kan)，在(zai)未來如果氫(qing)燃料電(dian)池(chi)汽(qi)車(che)攻克了氫(qing)氣儲存的(de)難點以(yi)及降低成本后，還是(shi)非(fei)常容易普及的(de)。
