純水電解(jie)制氫
把滿足要求的(de)電(dian)(dian)(dian)(dian)解水(shui)(電(dian)(dian)(dian)(dian)阻(zu)率(lv)大(da)于(yu)1MΩ/cm，電(dian)(dian)(dian)(dian)子(zi)或(huo)分析行業用(yong)(yong)(yong)的(de)去離子(zi)水(shui)或(huo)二次蒸餾水(shui)皆(jie)可)送入電(dian)(dian)(dian)(dian)解槽(cao)(cao)陽(yang)極(ji)室(shi)，通電(dian)(dian)(dian)(dian)后水(shui)便立刻在(zai)(zai)陽(yang)極(ji)分解：2H2O=4H++ 2O-2，分解成的(de)負氧離子(zi)(O-2)，隨即在(zai)(zai)陽(yang)極(ji)放出(chu)(chu)(chu)電(dian)(dian)(dian)(dian)子(zi)，形成氧氣(qi)(O2)，從(cong)陽(yang)極(ji)室(shi)排出(chu)(chu)(chu)，攜帶(dai)部份(fen)水(shui)進入水(shui)槽(cao)(cao)，水(shui)可循(xun)環(huan)使用(yong)(yong)(yong)，氧氣(qi)從(cong)水(shui)槽(cao)(cao)上蓋小(xiao)孔放入大(da)氣(qi)。氫質子(zi)以(yi)水(shui)合離子(zi)(H+•XH2O)的(de)形式，在(zai)(zai)電(dian)(dian)(dian)(dian)場力的(de)作(zuo)用(yong)(yong)(yong)下，通過(guo)SPE離子(zi)膜，到達(da)陰極(ji)吸收電(dian)(dian)(dian)(dian)子(zi)形成氫氣(qi)，從(cong)陰極(ji)室(shi)排出(chu)(chu)(chu)后，進入氣(qi)水(shui)分離器(qi)(qi)，在(zai)(zai)此除去從(cong)電(dian)(dian)(dian)(dian)解槽(cao)(cao)攜帶(dai)出(chu)(chu)(chu)的(de)大(da)部分水(shui)份(fen)，含微量(liang)水(shui)份(fen)的(de)氫氣(qi)再經(jing)干燥(zao)器(qi)(qi)吸濕后，純度便達(da)到99.999%以(yi)上。
堿液電解制氫
工(gong)作原(yuan)理是傳統隔膜(mo)堿液電(dian)(dian)(dian)解法。電(dian)(dian)(dian)解槽(cao)(cao)內(nei)的(de)(de)導電(dian)(dian)(dian)介質(zhi)為(wei)氫(qing)氧化鉀水溶液，兩(liang)極(ji)(ji)(ji)室(shi)的(de)(de)分隔物為(wei)航天電(dian)(dian)(dian)解設(she)備用(yong)(yong)隔膜(mo)，與端板合(he)為(wei)一體的(de)(de)耐(nai)蝕、傳質(zhi)良(liang)好的(de)(de)格柵電(dian)(dian)(dian)極(ji)(ji)(ji)等組成(cheng)電(dian)(dian)(dian)解槽(cao)(cao)。向兩(liang)極(ji)(ji)(ji)施加直流電(dian)(dian)(dian)后，水分子在電(dian)(dian)(dian)解槽(cao)(cao)的(de)(de)兩(liang)極(ji)(ji)(ji)立(li)刻(ke)發生(sheng)電(dian)(dian)(dian)化學反(fan)(fan)應，在陽極(ji)(ji)(ji)產生(sheng)氧氣(qi)，在陰極(ji)(ji)(ji)產生(sheng)氫(qing)氣(qi)。反(fan)(fan)應式如下：陽極(ji)(ji)(ji)： 2OH--2e → H2O+1/2O2↑ 陰 極(ji)(ji)(ji)： 2H2O +2e →2OH- +H2↑ 總反(fan)(fan)應式： 2H2O → 2 H2↑ +O2↑ 本儀(yi)(yi)器對壓控(kong)、過壓保護(hu)、流量(liang)(liang)顯(xian)示、流量(liang)(liang)追(zhui)蹤等均實行(xing)自動控(kong)制;使輸出氫(qing)氣(qi)能(neng)在恒(heng)壓下，根據氣(qi)相(xiang)色譜儀(yi)(yi)用(yong)(yong)氫(qing)氣(qi)量(liang)(liang)，實現全(quan)自動調節(jie)(在產氣(qi)量(liang)(liang)范圍內(nei))。
