氫能源動力汽車工作原理

氫(qing)(qing)(qing)動(dong)力汽車(che)分(fen)為兩(liang)種，氫(qing)(qing)(qing)內(nei)(nei)燃(ran)(ran)(ran)汽車(che)(HICEV)是以(yi)內(nei)(nei)燃(ran)(ran)(ran)機(ji)燃(ran)(ran)(ran)燒氫(qing)(qing)(qing)氣（通(tong)(tong)常透過分(fen)解甲烷或(huo)電(dian)解水取(qu)得）及(ji)空(kong)氣中(zhong)(zhong)的氧(yang)產生動(dong)力，推(tui)(tui)(tui)動(dong)的汽車(che)。而(er)氫(qing)(qing)(qing)燃(ran)(ran)(ran)料電(dian)池汽車(che)(Fuel cell vehicle-FCEV)是使氫(qing)(qing)(qing)或(huo)含氫(qing)(qing)(qing)物質及(ji)空(kong)氣中(zhong)(zhong)的氧(yang)通(tong)(tong)過燃(ran)(ran)(ran)料電(dian)池以(yi)產生電(dian)力，再以(yi)電(dian)力推(tui)(tui)(tui)動(dong)電(dian)動(dong)機(ji)，由(you)電(dian)動(dong)機(ji)推(tui)(tui)(tui)動(dong)車(che)輛。這類車(che)輛的發電(dian)機(ji)把氫(qing)(qing)(qing)的化(hua)學能轉(zhuan)換為機(ji)械能，或(huo)者是通(tong)(tong)過燃(ran)(ran)(ran)燒的內(nei)(nei)燃(ran)(ran)(ran)機(ji)中(zhong)(zhong)的氫(qing)(qing)(qing)，或(huo)通(tong)(tong)過在燃(ran)(ran)(ran)料電(dian)池中(zhong)(zhong)的氧(yang)與氫(qing)(qing)(qing)反應來運行(xing)電(dian)動(dong)機(ji)。廣泛使用氫(qing)(qing)(qing)助長交通(tong)(tong)是在提議中(zhong)(zhong)的氫(qing)(qing)(qing)經濟的一個關鍵因素。

氫能源汽車與氫燃料電池車的區別

首先，氫(qing)燃料電(dian)(dian)(dian)池(chi)是使用氫(qing)這種化學元素制造成儲存能量的電(dian)(dian)(dian)池(chi)，它與干電(dian)(dian)(dian)池(chi)、蓄電(dian)(dian)(dian)池(chi)的區(qu)別就是，前者是一種儲能裝置，是將(jiang)(jiang)電(dian)(dian)(dian)能儲存起(qi)來，需要(yao)時再釋(shi)放(fang)出來。而氫(qing)燃料電(dian)(dian)(dian)池(chi)則是一種發(fa)電(dian)(dian)(dian)裝置，類(lei)似(si)于(yu)發(fa)電(dian)(dian)(dian)廠，是將(jiang)(jiang)化學能直接轉化為電(dian)(dian)(dian)能的電(dian)(dian)(dian)化學發(fa)電(dian)(dian)(dian)裝置。

其次，氫燃(ran)料(liao)電池車不(bu)會對環境構成污染，并且(qie)能(neng)夠完全擺脫化(hua)石(shi)(shi)燃(ran)料(liao)的束縛。它的排放物(wu)只(zhi)有水(shui)蒸氣和熱量(liang)。而另一方面，氫氣可(ke)以從多種原料(liao)中獲(huo)取，比如天然氣等(deng)化(hua)石(shi)(shi)燃(ran)料(liao)，當化(hua)石(shi)(shi)燃(ran)料(liao)枯(ku)竭時，還可(ke)以直接利用太陽能(neng)和風(feng)能(neng)電解水(shui)獲(huo)得，總而言之，從理論上來講，氫氣是一種永遠不(bu)會耗竭的資源。

總結，氫燃料汽車的好處顯而易(yi)見(jian)，未來消費者可選(xuan)擇(ze)的真正(zheng)的新(xin)能源汽車(che)(che)，除了純電動汽車(che)(che)之外，肯定還有氫燃料電池汽車(che)(che)。

氫(qing)燃料(liao)(liao)電池(chi)汽(qi)(qi)(qi)車(che)和純電動(dong)汽(qi)(qi)(qi)車(che)，其實都(dou)是(shi)電動(dong)汽(qi)(qi)(qi)車(che)，區別(bie)在(zai)于(yu)純電動(dong)汽(qi)(qi)(qi)車(che)是(shi)直接向電池(chi)里充(chong)電，而氫(qing)燃料(liao)(liao)電池(chi)汽(qi)(qi)(qi)車(che)是(shi)給汽(qi)(qi)(qi)車(che)加氫(qing)，通過氫(qing)氧離子(zi)的(de)化學反應(ying)“現場發電”。
