1、原理(li)不(bu)同

（1）純電(dian)動(dong)(dong)汽(qi)(qi)車的(de)原理是依靠電(dian)池(chi)儲備能源，用電(dian)機(ji)驅動(dong)(dong)汽(qi)(qi)車行駛。最核心部分就是電(dian)池(chi)、電(dian)控、電(dian)機(ji)的(de)三電(dian)技術。

（2）燃料電(dian)(dian)(dian)(dian)池汽車以氫(qing)氣為(wei)能(neng)源，工作原理(li)是把氫(qing)輸入(ru)燃料電(dian)(dian)(dian)(dian)池中，氫(qing)原子的電(dian)(dian)(dian)(dian)子被質子交換膜阻隔，通(tong)過外電(dian)(dian)(dian)(dian)路從負(fu)極(ji)傳導到正極(ji)，成為(wei)電(dian)(dian)(dian)(dian)能(neng)驅動(dong)電(dian)(dian)(dian)(dian)動(dong)機。區別于傳統的干電(dian)(dian)(dian)(dian)池、蓄電(dian)(dian)(dian)(dian)池，普通(tong)電(dian)(dian)(dian)(dian)池是一(yi)種儲能(neng)裝(zhuang)置(zhi)(zhi)，是把電(dian)(dian)(dian)(dian)能(neng)貯存(cun)起來(lai)，需要時再釋放出(chu)來(lai)；氫(qing)燃料電(dian)(dian)(dian)(dian)池嚴格地說是一(yi)種發電(dian)(dian)(dian)(dian)裝(zhuang)置(zhi)(zhi)，就像發電(dian)(dian)(dian)(dian)廠一(yi)樣，是把化(hua)學(xue)能(neng)直(zhi)接轉化(hua)為(wei)電(dian)(dian)(dian)(dian)能(neng)的電(dian)(dian)(dian)(dian)化(hua)學(xue)發電(dian)(dian)(dian)(dian)裝(zhuang)置(zhi)(zhi)。

2、續航能力不同

燃料(liao)電(dian)(dian)(dian)池(chi)汽車的續(xu)航里(li)程一般(ban)都(dou)是(shi)400公里(li)以上，和傳統的燃油車非常接近。而(er)對(dui)純電(dian)(dian)(dian)動汽車來說，更長的續(xu)航里(li)程意味著(zhu)更重更貴的鋰電(dian)(dian)(dian)池(chi)包(bao)。再(zai)加上深度放(fang)電(dian)(dian)(dian)會影(ying)響鋰電(dian)(dian)(dian)池(chi)壽命，也就是(shi)不能(neng)像傳統汽車那樣(yang)將(jiang)油用干再(zai)加滿，所以實際續(xu)航里(li)程比宣稱的還要低不少。雖然燃料(liao)電(dian)(dian)(dian)池(chi)汽車的價格(ge)目前更高，但(dan)從(cong)前景(jing)來說，同樣(yang)續(xu)航里(li)程的情況下，燃料(liao)電(dian)(dian)(dian)池(chi)汽車的成本會低于純電(dian)(dian)(dian)動汽車。

3、起步速度不同

燃(ran)(ran)(ran)料電池(chi)(chi)汽車(che)和純電動汽車(che)兩者之(zhi)間(jian)(jian)的(de)(de)(de)(de)起步的(de)(de)(de)(de)速度(du)還是(shi)有(you)所(suo)區別的(de)(de)(de)(de)，主要(yao)的(de)(de)(de)(de)原因就是(shi)燃(ran)(ran)(ran)料電池(chi)(chi)的(de)(de)(de)(de)燃(ran)(ran)(ran)料在車(che)的(de)(de)(de)(de)儲存罐當中(zhong)反應是(shi)需要(yao)時(shi)間(jian)(jian)的(de)(de)(de)(de)，從(cong)車(che)輛的(de)(de)(de)(de)構造上面來(lai)說，燃(ran)(ran)(ran)料車(che)的(de)(de)(de)(de)乘(cheng)坐空間(jian)(jian)并沒有(you)電動汽車(che)的(de)(de)(de)(de)乘(cheng)坐空間(jian)(jian)舒適(shi)，燃(ran)(ran)(ran)料電池(chi)(chi)需要(yao)大的(de)(de)(de)(de)儲存罐，會占據(ju)一定的(de)(de)(de)(de)內(nei)部空間(jian)(jian)。

4、燃料/電能補充(chong)不同

燃料電(dian)(dian)池(chi)汽(qi)車(che)的加氫是(shi)物理過(guo)程，3分鐘左右便可加滿。純電(dian)(dian)動汽(qi)車(che)的電(dian)(dian)池(chi)充(chong)(chong)(chong)電(dian)(dian)是(shi)電(dian)(dian)解(jie)反應，充(chong)(chong)(chong)電(dian)(dian)的時候需要控制(zhi)否則會有副反應發生(sheng)，目前快充(chong)(chong)(chong)是(shi)半個小(xiao)時充(chong)(chong)(chong)滿80%，在(zai)將來很(hen)長一段時間內比較(jiao)難提高(gao)充(chong)(chong)(chong)電(dian)(dian)速度。快速換電(dian)(dian)池(chi)的解(jie)決(jue)方案受制(zhi)于電(dian)(dian)池(chi)質(zhi)量、所(suo)有權、電(dian)(dian)池(chi)型號等(deng)問題，可能對(dui)于公交車(che)有更多幫助(zhu)，對(dui)私(si)家乘(cheng)用車(che)來說(shuo)，前景比較(jiao)渺茫(mang)。

5、發展前景

根據目前的(de)發(fa)展來(lai)看，純電動汽(qi)車由于(yu)成本(ben)更低，在(zai)短時間內相(xiang)比氫(qing)燃料電池(chi)汽(qi)車還是(shi)比較有優勢的(de)。根據長遠來(lai)看，在(zai)未來(lai)如果氫(qing)燃料電池(chi)汽(qi)車攻克(ke)了氫(qing)氣儲存的(de)難點以及(ji)降低成本(ben)后，還是(shi)非常(chang)容易普(pu)及(ji)的(de)。
