燃料電池的優點
發電效率高、環境污染小、比能量高、噪音低、燃料范圍廣、可靠性高、易于建設。如需(xu)給(gei)自(zi)己的愛車更換燃料電池(chi),建(jian)議先(xian)了解燃料電池品牌,可以輕松(song)享(xiang)受燃料(liao)電池(chi)帶來(lai)的便利。
燃料電池汽車的優點
燃料電(dian)池(chi)汽(qi)車(che)(che)也是(shi)電(dian)動汽(qi)車(che)(che),只不過“電(dian)池(chi)”是(shi)氫(qing)(qing)氧混合(he)燃料電(dian)池(chi)。和(he)普(pu)通化學(xue)電(dian)池(chi)相比,燃料電(dian)池(chi)可以(yi)補充燃料,通常(chang)是(shi)補充氫(qing)(qing)氣。一些燃料電(dian)池(chi)能使(shi)(shi)用甲(jia)烷和(he)汽(qi)油作為燃料,但通常(chang)是(shi)限制(zhi)在(zai)電(dian)廠和(he)叉車(che)(che)等工業領域使(shi)(shi)用。
優(you)點是零排放或近似零排放,綠色環保;能(neng)(neng)量轉換效率高,節(jie)約能(neng)(neng)源;燃料(liao)多樣化(hua),優(you)化(hua)了能(neng)(neng)源消(xiao)耗結構;續駛里程(cheng)長,性能(neng)(neng)優(you)于其他電(dian)(dian)池(chi)的電(dian)(dian)動汽車;過(guo)載能(neng)(neng)力強;運行平穩、低噪聲。
氫燃料電池原理
氫燃料電(dian)(dian)池是(shi)使(shi)用氫這種化學元素,制造成儲存能量(liang)的電(dian)(dian)池。其(qi)基本原理(li)是(shi)電(dian)(dian)解水(shui)的逆反(fan)應(ying),把氫和氧分別供給陽(yang)極和陰(yin)(yin)極,氫通(tong)過陽(yang)極向外(wai)擴散和電(dian)(dian)解質發(fa)生反(fan)應(ying)后,放出(chu)電(dian)(dian)子通(tong)過外(wai)部的負載到達陰(yin)(yin)極。
什么是甲醇燃料電池
甲(jia)醇(chun)燃料電(dian)(dian)池(chi)是直(zhi)接使(shi)用甲(jia)醇(chun)水溶液或蒸(zheng)汽甲(jia)醇(chun)為燃料供(gong)給來源(yuan),而不需通(tong)過(guo)(guo)甲(jia)醇(chun)、汽油及天然(ran)氣的(de)重(zhong)整制氫以供(gong)發電(dian)(dian)。其(qi)原理是甲(jia)醇(chun)在(zai)陽極轉(zhuan)換成(cheng)二氧(yang)化碳(tan),質(zhi)子(zi)和電(dian)(dian)子(zi),如同標準的(de)質(zhi)子(zi)交(jiao)換膜燃料電(dian)(dian)池(chi)一樣,質(zhi)子(zi)透過(guo)(guo)質(zhi)子(zi)交(jiao)換膜在(zai)陰極與氧(yang)反應,電(dian)(dian)子(zi)通(tong)過(guo)(guo)外電(dian)(dian)路到達陰極,并做功。
什么是質子交換膜燃料電池
質子(zi)交(jiao)換(huan)膜(mo)燃(ran)(ran)料電(dian)(dian)池是燃(ran)(ran)料電(dian)(dian)池的一(yi)種,在原理上相(xiang)當(dang)于(yu)水電(dian)(dian)解(jie)的“逆”裝置。其單電(dian)(dian)池由陽(yang)極(ji)、陰極(ji)和質子(zi)交(jiao)換(huan)膜(mo)組成,陽(yang)極(ji)為(wei)氫燃(ran)(ran)料發生氧化(hua)的場所(suo),陰極(ji)為(wei)氧化(hua)劑還(huan)原的場所(suo),兩(liang)極(ji)都含有(you)加速電(dian)(dian)極(ji)電(dian)(dian)化(hua)學反(fan)應的催(cui)化(hua)劑,質子(zi)交(jiao)換(huan)膜(mo)作為(wei)傳遞(di)H+的介質,只允(yun)許(xu)H+通(tong)過(guo),而H2失去的電(dian)(dian)子(zi)則從導線(xian)通(tong)過(guo)。工作時相(xiang)當(dang)于(yu)一(yi)直流電(dian)(dian)源,陽(yang)極(ji)即電(dian)(dian)源負(fu)極(ji),陰極(ji)即電(dian)(dian)源正極(ji)。
