燃料電(dian)(dian)(dian)(dian)池汽車(che)的(de)(de)工(gong)(gong)作原(yuan)理是，作為燃料的(de)(de)氫在(zai)汽車(che)搭載的(de)(de)燃料電(dian)(dian)(dian)(dian)池中，與(yu)大氣中的(de)(de)氧氣發生氧化還原(yuan)化學反(fan)應，產生出(chu)電(dian)(dian)(dian)(dian)能來帶(dai)動(dong)(dong)(dong)(dong)(dong)電(dian)(dian)(dian)(dian)動(dong)(dong)(dong)(dong)(dong)機(ji)工(gong)(gong)作，由電(dian)(dian)(dian)(dian)動(dong)(dong)(dong)(dong)(dong)機(ji)帶(dai)動(dong)(dong)(dong)(dong)(dong)汽車(che)中的(de)(de)機(ji)械(xie)傳(chuan)動(dong)(dong)(dong)(dong)(dong)結構(gou)，進而(er)(er)帶(dai)動(dong)(dong)(dong)(dong)(dong)汽車(che)的(de)(de)前橋（或后橋）等行走機(ji)械(xie)結構(gou)工(gong)(gong)作，從而(er)(er)驅動(dong)(dong)(dong)(dong)(dong)電(dian)(dian)(dian)(dian)動(dong)(dong)(dong)(dong)(dong)汽車(che)前進。

燃料電(dian)(dian)池(chi)的(de)反應結果會產(chan)生極少的(de)二氧(yang)化(hua)(hua)碳和氮氧(yang)化(hua)(hua)物，副產(chan)品(pin)主(zhu)要產(chan)生水(shui)，因此被(bei)稱為綠(lv)色(se)新(xin)型環(huan)保汽車。燃料電(dian)(dian)池(chi)汽車是(shi)電(dian)(dian)動汽車的(de)一種，其核心部件燃料電(dian)(dian)池(chi)。通過氫氣(qi)和氧(yang)氣(qi)的(de)化(hua)(hua)學作用，而不是(shi)經過燃燒，直接變成(cheng)電(dian)(dian)能動力。

燃(ran)料(liao)(liao)電(dian)(dian)池(chi)汽(qi)車(che)(che)的(de)(de)氫(qing)(qing)燃(ran)料(liao)(liao)能通(tong)過(guo)幾種途徑(jing)得到(dao)。有(you)(you)些(xie)車(che)(che)輛(liang)直接攜(xie)帶著純(chun)氫(qing)(qing)燃(ran)料(liao)(liao)，另外一些(xie)車(che)(che)輛(liang)有(you)(you)可能裝有(you)(you)燃(ran)料(liao)(liao)重整(zheng)器，能將烴(jing)類燃(ran)料(liao)(liao)轉化為富氫(qing)(qing)氣(qi)體。單個的(de)(de)燃(ran)料(liao)(liao)電(dian)(dian)池(chi)必(bi)須(xu)結合成燃(ran)料(liao)(liao)電(dian)(dian)池(chi)組，以便獲得必(bi)需的(de)(de)動(dong)力，滿足車(che)(che)輛(liang)使用的(de)(de)要求。
