Alkaline cell hydrogen ntau lawm yog ib qho kev paub tab ntawm electrolytic hydrogen ntau lawm technology. Alkaline cell muaj kev nyab xeeb thiab txhim khu kev qha, nrog lub neej ntev ntawm 15 xyoo, thiab tau siv dav hauv kev lag luam. Kev ua haujlwm ntawm alkaline cell feem ntau yog 42% ~ 78%. Ob peb xyoos dhau los, alkaline electrolytic hlwb tau nce qib hauv ob qhov tseem ceeb. Ntawm ib sab, kev txhim kho ntawm tes ua haujlwm tau zoo dua qub thiab cov nqi khiav lag luam cuam tshuam nrog kev siv hluav taws xob tau raug txo. Ntawm qhov tod tes, kev khiav hauj lwm tam sim no ceev nce thiab cov nqi peev txo qis.
Lub hauv paus ntsiab lus ua haujlwm ntawm alkaline electrolyzer yog qhia hauv daim duab. Lub roj teeb muaj ob lub electrodes sib cais los ntawm huab cua nruj diaphragm. Lub roj teeb sib dhos yog immersed nyob rau hauv ib tug siab concentration ntawm alkaline kua electrolyte KOH (20% mus rau 30%) kom maximize ionic conductivity. NaOH thiab NaCl cov kev daws teeb meem kuj tuaj yeem siv los ua cov electrolytes, tab sis lawv tsis siv ntau. Lub ntsiab tsis zoo ntawm electrolytes yog tias lawv corrosive. Lub cell ua haujlwm ntawm qhov kub ntawm 65 ° C txog 100 ° C. Lub cathode ntawm lub cell tsim hydrogen, thiab qhov tshwm sim OH - ntws los ntawm lub diaphragm mus rau lub anode, uas nws recombines los tsim oxygen.
Advanced alkaline electrolytic hlwb yog tsim rau loj-scale hydrogen ntau lawm. Alkaline electrolytic hlwb ua los ntawm qee cov tuam txhab muaj peev xwm ua tau hydrogen ntau ntawm (500 ~ 760Nm3 / h), nrog rau kev siv zog ntawm 2150 ~ 3534kW. Hauv kev xyaum, txhawm rau tiv thaiv kev tsim cov roj sib tov sib xyaw, cov txiaj ntsig hydrogen tsuas yog txwv rau 25% mus rau 100% ntawm qhov ntsuas qhov ntsuas, qhov siab tshaj plaws tam sim no tso cai yog kwv yees li 0.4A / cm2, kev ua haujlwm kub yog 5 txog 100 ° C, thiab qhov siab tshaj plaws electrolytic siab yog ze li ntawm 2.5 txog 3.0 MPa. Thaum lub siab electrolytic siab dhau lawm, tus nqi peev nce ntxiv thiab tsim kev pheej hmoo ntawm cov roj sib xyaw ua ke nce ntxiv. Tsis muaj cov cuab yeej ua kom huv huv, qhov purity ntawm hydrogen tsim los ntawm alkaline cell electrolysis tuaj yeem ncav cuag 99%. Alkaline electrolytic cell electrolytic dej yuav tsum yog ntshiab, txhawm rau tiv thaiv cov electrode thiab kev ua haujlwm zoo, dej conductivity tsawg dua 5S / cm.
