Ukukhiqizwa kwe-alkaline cell hydrogen kuwubuchwepheshe obuvuthiwe bokukhiqiza i-electrolytic hydrogen. Iseli le-alkaline liphephile futhi linokwethenjelwa, liphila iminyaka engu-15, futhi lisetshenziswe kabanzi kwezentengiso. Ukusebenza kahle kweseli le-alkaline kuvamise ukuba ngu-42% ~ 78%. Eminyakeni embalwa edlule, amaseli e-alkaline electrolytic enze inqubekelaphambili ezicini ezimbili eziyinhloko. Ngakolunye uhlangothi, ukusebenza kahle kwamaseli okuthuthukisiwe kwenziwe ngcono futhi nezindleko zokusebenza ezihambisana nokusetshenziswa kukagesi zehlisiwe. Ngakolunye uhlangothi, ukuminyana kwamanje kokusebenza kuyenyuka futhi izindleko zokutshala ziyehla.
Umgomo wokusebenza we-alkaline electrolyzer uboniswa esithombeni. Ibhethri liqukethe ama-electrode amabili ahlukaniswe i-diaphragm ebamba umoya. Ukuhlanganiswa kwebhethri kucwiliswa ekuhlanganiseni okuphezulu kwe-alkaline liquid electrolyte KOH(20% kuya ku-30%) ukuze kukhuliswe ukuqhutshwa kwe-ionic. Izixazululo ze-NaOH ne-NaCl nazo zingasetshenziswa njengama-electrolyte, kodwa azivamile ukusetshenziswa. Ububi obukhulu bama-electrolyte ukuthi ayagqwala. Iseli lisebenza emazingeni okushisa angama-65 °C kuya ku-100°C. I-cathode yeseli ikhiqiza i-hydrogen, futhi i-OH ewumphumela - igeleza nge-diaphragm iye ku-anode, lapho iphinde ihlangane khona ukuze ikhiqize umoya-mpilo.
Amaseli e-alkaline electrolytic athuthukile afanele ukukhiqizwa kwe-hydrogen ngezinga elikhulu. Amaseli e-alkaline electrolytic enziwe abanye abakhiqizi banamandla okukhiqiza i-hydrogen aphezulu kakhulu ku-(500 ~ 760Nm3/h), asebenzisa amandla ahambisanayo angu-2150 ~ 3534kW. Ngokwenza njalo, ukuvimbela ukudalwa kwezingxube zegesi ezivuthayo, isivuno se-hydrogen sikhawulelwe ku-25% kuya ku-100% webanga elilinganiselwe, ubukhulu obuvunyelwe bamanje obuvunyelwe bumayelana ne-0.4A / cm2, izinga lokushisa lokusebenza liyi-5 kuya ku-100 ° C, futhi ingcindezi enkulu ye-electrolytic isondele ku-2.5 kuya ku-3.0 MPa. Uma ingcindezi ye-electrolytic iphezulu kakhulu, izindleko zokutshala ziyakhuphuka kanye nengozi yokwakheka kwengxube yegesi eyingozi ikhula kakhulu. Ngaphandle kwanoma iyiphi insiza yokuhlanza eyisizayo, ukuhlanzeka kwe-hydrogen okukhiqizwa yi-alkaline cell electrolysis kungafinyelela ku-99%. Amanzi e-alkaline electrolytic cell electrolytic kumele abe msulwa, ukuze kuvikelwe i-electrode nokusebenza okuphephile, ukuqhutshwa kwamanzi kungaphansi kuka-5S/cm.
