1、原理(li)不同

（1）純電(dian)(dian)動汽(qi)車的(de)原(yuan)理是依(yi)靠電(dian)(dian)池(chi)儲備(bei)能源(yuan)，用電(dian)(dian)機驅動汽(qi)車行(xing)駛。最核心部分就(jiu)是電(dian)(dian)池(chi)、電(dian)(dian)控、電(dian)(dian)機的(de)三電(dian)(dian)技術。

（2）燃(ran)料電(dian)(dian)(dian)(dian)(dian)池汽車以氫氣(qi)為能(neng)源，工作原理是(shi)把氫輸入燃(ran)料電(dian)(dian)(dian)(dian)(dian)池中，氫原子(zi)(zi)的(de)電(dian)(dian)(dian)(dian)(dian)子(zi)(zi)被質子(zi)(zi)交換膜阻(zu)隔(ge)，通(tong)過外(wai)電(dian)(dian)(dian)(dian)(dian)路從負(fu)極傳導(dao)到正極，成(cheng)為電(dian)(dian)(dian)(dian)(dian)能(neng)驅動(dong)電(dian)(dian)(dian)(dian)(dian)動(dong)機。區別于傳統(tong)的(de)干電(dian)(dian)(dian)(dian)(dian)池、蓄電(dian)(dian)(dian)(dian)(dian)池，普(pu)通(tong)電(dian)(dian)(dian)(dian)(dian)池是(shi)一種儲能(neng)裝(zhuang)置，是(shi)把電(dian)(dian)(dian)(dian)(dian)能(neng)貯存起來，需要時再釋放(fang)出(chu)來；氫燃(ran)料電(dian)(dian)(dian)(dian)(dian)池嚴格地說是(shi)一種發電(dian)(dian)(dian)(dian)(dian)裝(zhuang)置，就像發電(dian)(dian)(dian)(dian)(dian)廠一樣，是(shi)把化學(xue)能(neng)直接轉(zhuan)化為電(dian)(dian)(dian)(dian)(dian)能(neng)的(de)電(dian)(dian)(dian)(dian)(dian)化學(xue)發電(dian)(dian)(dian)(dian)(dian)裝(zhuang)置。

2、續航能力不同

燃料(liao)電(dian)(dian)(dian)池汽車(che)的(de)(de)(de)續(xu)航(hang)里程(cheng)一般都是400公(gong)里以上，和(he)傳統的(de)(de)(de)燃油車(che)非常接近。而對純(chun)電(dian)(dian)(dian)動汽車(che)來說，更(geng)(geng)長的(de)(de)(de)續(xu)航(hang)里程(cheng)意味著(zhu)更(geng)(geng)重更(geng)(geng)貴的(de)(de)(de)鋰電(dian)(dian)(dian)池包。再(zai)加(jia)上深度(du)放電(dian)(dian)(dian)會影響鋰電(dian)(dian)(dian)池壽命，也(ye)就(jiu)是不能像傳統汽車(che)那樣將油用干再(zai)加(jia)滿(man)，所以實際續(xu)航(hang)里程(cheng)比宣稱的(de)(de)(de)還要(yao)低不少。雖然燃料(liao)電(dian)(dian)(dian)池汽車(che)的(de)(de)(de)價格目前更(geng)(geng)高，但從前景(jing)來說，同樣續(xu)航(hang)里程(cheng)的(de)(de)(de)情況(kuang)下，燃料(liao)電(dian)(dian)(dian)池汽車(che)的(de)(de)(de)成本會低于純(chun)電(dian)(dian)(dian)動汽車(che)。

3、起步速度不同

燃(ran)(ran)料(liao)(liao)電池(chi)汽車(che)和純電動(dong)汽車(che)兩者之間(jian)(jian)的(de)(de)(de)(de)(de)起步的(de)(de)(de)(de)(de)速度(du)還是有(you)(you)所區(qu)別的(de)(de)(de)(de)(de)，主(zhu)要(yao)(yao)的(de)(de)(de)(de)(de)原(yuan)因就是燃(ran)(ran)料(liao)(liao)電池(chi)的(de)(de)(de)(de)(de)燃(ran)(ran)料(liao)(liao)在(zai)車(che)的(de)(de)(de)(de)(de)儲存(cun)罐(guan)當中(zhong)反(fan)應(ying)是需(xu)要(yao)(yao)時間(jian)(jian)的(de)(de)(de)(de)(de)，從(cong)車(che)輛的(de)(de)(de)(de)(de)構造(zao)上面來說，燃(ran)(ran)料(liao)(liao)車(che)的(de)(de)(de)(de)(de)乘坐空(kong)(kong)間(jian)(jian)并沒有(you)(you)電動(dong)汽車(che)的(de)(de)(de)(de)(de)乘坐空(kong)(kong)間(jian)(jian)舒適，燃(ran)(ran)料(liao)(liao)電池(chi)需(xu)要(yao)(yao)大的(de)(de)(de)(de)(de)儲存(cun)罐(guan)，會占據(ju)一定的(de)(de)(de)(de)(de)內部空(kong)(kong)間(jian)(jian)。

4、燃料/電能補充不同

燃料(liao)電池(chi)汽(qi)(qi)車(che)的(de)加(jia)氫是物(wu)理過程，3分(fen)鐘左右便可加(jia)滿。純電動汽(qi)(qi)車(che)的(de)電池(chi)充(chong)(chong)(chong)電是電解(jie)反應(ying)，充(chong)(chong)(chong)電的(de)時(shi)(shi)(shi)候需要控制否則會有副反應(ying)發生(sheng)，目前快(kuai)充(chong)(chong)(chong)是半個小(xiao)時(shi)(shi)(shi)充(chong)(chong)(chong)滿80%，在將來很(hen)長一段(duan)時(shi)(shi)(shi)間內比較難提(ti)高充(chong)(chong)(chong)電速度。快(kuai)速換電池(chi)的(de)解(jie)決(jue)方案受制于電池(chi)質量、所(suo)有權(quan)、電池(chi)型號(hao)等問題(ti)，可能對于公交車(che)有更多(duo)幫助(zhu)，對私家乘用車(che)來說，前景比較渺茫。

5、發展前景

根(gen)據(ju)目前(qian)的發展來看(kan)，純電(dian)動汽(qi)車由于成(cheng)本更低，在(zai)短時間內(nei)相比(bi)氫(qing)燃(ran)料電(dian)池(chi)汽(qi)車還(huan)是(shi)比(bi)較有優勢的。根(gen)據(ju)長(chang)遠(yuan)來看(kan)，在(zai)未來如果氫(qing)燃(ran)料電(dian)池(chi)汽(qi)車攻克了(le)氫(qing)氣儲存的難點以及降低成(cheng)本后，還(huan)是(shi)非常(chang)容易普及的。
