燃料電(dian)(dian)池不能儲電(dian)(dian)，也就是立即使(shi)用(yong)du的(de)，沒(mei)有(you)加燃料就沒(mei)有(you)zhi電(dian)(dian)的(de)。鋰電(dian)(dian)池是可(ke)(ke)以(yi)儲電(dian)(dian)的(de)，方便攜(xie)帶dao，可(ke)(ke)以(yi)作為移動電(dian)(dian)源(yuan)的(de)電(dian)(dian)池使(shi)用(yong)。
1、燃(ran)料(liao)電(dian)(dian)池(chi)(Fuel Cell)是(shi)一種將(jiang)存在于燃(ran)料(liao)與氧(yang)化劑中(zhong)的化學能直接轉化為電(dian)(dian)能的發電(dian)(dian)裝置。燃(ran)料(liao)和(he)空氣(qi)分別送進(jin)燃(ran)料(liao)電(dian)(dian)池(chi)，電(dian)(dian)就(jiu)被奇妙地(di)生產出來。它(ta)從外表上看(kan)有正(zheng)負極和(he)電(dian)(dian)解(jie)質等(deng)，像一個 蓄電(dian)(dian)池(chi)，但實質上它(ta)不能“儲電(dian)(dian)”而是(shi)一個“發電(dian)(dian)廠(chang)”。但是(shi)，它(ta)需(xu)要電(dian)(dian)極和(he)電(dian)(dian)解(jie)質以(yi)及氧(yang)化還原反應才能發電(dian)(dian)。
2、2014年2月(yue)19日據物(wu)理學家組織網報道，美(mei)國科學家開發出一種直接以(yi)生物(wu)質為(wei)原料(liao)的(de)低溫燃(ran)料(liao)電(dian)池(chi)。這種燃(ran)料(liao)電(dian)池(chi)只(zhi)需借助太陽(yang)能或廢(fei)熱就能將稻(dao)草、鋸末(mo)、藻(zao)類甚(shen)至有機肥料(liao)轉(zhuan)化為(wei)電(dian)能，能量密度比基于纖(xian)維素的(de)微生物(wu)燃(ran)料(liao)電(dian)池(chi)高出近100倍。
3、燃料電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)是(shi)將(jiang)燃料具有的(de)(de)化(hua)學能(neng)直接變為(wei)電(dian)(dian)(dian)能(neng)的(de)(de)發電(dian)(dian)(dian)裝置(zhi)。燃料電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)其原理是(shi)一(yi)種(zhong)電(dian)(dian)(dian)化(hua)學裝置(zhi)，其組(zu)成與一(yi)般電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)相(xiang)同。其單體電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)是(shi)由正(zheng)負兩(liang)個電(dian)(dian)(dian)極(ji)(負極(ji)即燃料電(dian)(dian)(dian)極(ji)和(he)正(zheng)極(ji)即氧(yang)化(hua)劑電(dian)(dian)(dian)極(ji))以及(ji)電(dian)(dian)(dian)解(jie)質(zhi)組(zu)成。不同的(de)(de)是(shi)一(yi)般電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)的(de)(de)活(huo)性(xing)物(wu)質(zhi)貯存在電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)內部，因此，限制了電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)容量。而燃料電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)的(de)(de)正(zheng)、負極(ji)本(ben)身不包含活(huo)性(xing)物(wu)質(zhi)，只是(shi)個催化(hua)轉換(huan)元件。因此燃料電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)是(shi)名(ming)符其實的(de)(de)把 化(hua)學能(neng)轉化(hua)為(wei) 電(dian)(dian)(dian)能(neng)的(de)(de)能(neng)量轉換(huan)機器(qi)。
4、鋰(li)(li)(li)(li)電池(chi)(chi)是一(yi)類由鋰(li)(li)(li)(li)金屬或鋰(li)(li)(li)(li)合金為負極材料(liao)、使(shi)用非水電解質溶液(ye)的電池(chi)(chi)。最早出現的鋰(li)(li)(li)(li)電池(chi)(chi)來(lai)自于(yu)偉大的發(fa)明家愛迪生，使(shi)用以下反應(ying)：Li+MnO2=LiMnO2該反應(ying)為氧化(hua)還原(yuan)反應(ying)，放(fang)電。由于(yu)鋰(li)(li)(li)(li)金屬的化(hua)學特性非常活潑，使(shi)得鋰(li)(li)(li)(li)金屬的加(jia)工、保存、使(shi)用，對環境要求(qiu)非常高。所以，鋰(li)(li)(li)(li)電池(chi)(chi)長期沒(mei)有得到應(ying)用。現在鋰(li)(li)(li)(li)電池(chi)(chi)已經成為了(le)主流。
5、隨著二(er)十(shi)(shi)世紀微電(dian)(dian)(dian)(dian)(dian)(dian)子技(ji)術的(de)(de)(de)(de)(de)發(fa)展，小型化的(de)(de)(de)(de)(de)設(she)備(bei)(bei)日益增多，對電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)提出了(le)很(hen)高的(de)(de)(de)(de)(de)要求(qiu)。鋰(li)(li)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)隨之進(jin)入了(le)大(da)規模的(de)(de)(de)(de)(de)實用(yong)(yong)階段。最早得以(yi)應用(yong)(yong)的(de)(de)(de)(de)(de)是(shi)鋰(li)(li)亞原電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)，用(yong)(yong)于(yu)(yu)心臟起搏器中(zhong)。由(you)于(yu)(yu)鋰(li)(li)亞電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)的(de)(de)(de)(de)(de)自放電(dian)(dian)(dian)(dian)(dian)(dian)率極低(di)，放電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)壓十(shi)(shi)分(fen)平緩。使得起搏器植入人體(ti)長期使用(yong)(yong)成(cheng)為(wei)可(ke)能。鋰(li)(li)錳電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)一般有(you)高于(yu)(yu)3.0伏的(de)(de)(de)(de)(de)標稱電(dian)(dian)(dian)(dian)(dian)(dian)壓，更適合作集成(cheng)電(dian)(dian)(dian)(dian)(dian)(dian)路(lu)電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)，廣(guang)泛用(yong)(yong)于(yu)(yu)計(ji)算機、計(ji)算器、手(shou)表中(zhong)。現在，鋰(li)(li)離子電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)大(da)量應用(yong)(yong)在手(shou)機、筆記(ji)本電(dian)(dian)(dian)(dian)(dian)(dian)腦、電(dian)(dian)(dian)(dian)(dian)(dian)動(dong)工具、電(dian)(dian)(dian)(dian)(dian)(dian)動(dong)車(che)、路(lu)燈(deng)備(bei)(bei)用(yong)(yong)電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)、航燈(deng)、家用(yong)(yong)小電(dian)(dian)(dian)(dian)(dian)(dian)器上(shang)，可(ke)以(yi)說是(shi)最大(da)的(de)(de)(de)(de)(de)應用(yong)(yong)群體(ti)。
