Kugadzirwa kwehydrogen yemasero eAlkaline itekinoroji yekugadzira hydrogen yemagetsi yakakura. Masero eAlkaline akachengeteka uye akavimbika, ane hupenyu hwemakore gumi nemashanu, uye ave achishandiswa zvakanyanya mukutengeserana. Kushanda zvakanaka kwemasero ealkaline kunowanzova 42% ~ 78%. Mumakore mashoma apfuura, masero ealkaline electrolytic akafambira mberi muzvikamu zviviri zvikuru. Kune rumwe rutivi, kushanda zvakanaka kwemasero kwakavandudzika uye mari yekushanda inobatanidzwa nekushandiswa kwemagetsi yakadzikira. Kune rumwe rutivi, huwandu hwemagetsi ekushanda hunowedzera uye mari yekudyara inoderera.
Pfungwa yekushanda kwealkaline electrolyzer inoratidzwa mumufananidzo. Bhatiri rine maerekitironi maviri akaparadzaniswa nediaphragm isina mhepo. Kuunganidzwa kwebhatiri kunonyudzwa muhuwandu hwakawanda hwealkaline liquid electrolyte KOH (20% kusvika 30%) kuti iwedzere ionic conductivity. Mhinduro dzeNaOH neNaCl dzinogonawo kushandiswa semaerekitironi, asi hadziwanzo shandiswa. Dambudziko guru remaerekitironi nderekuti anoparadza. Sero rinoshanda patembiricha ye65 °C kusvika 100°C. Cathode yesero rinoburitsa hydrogen, uye OH inobuda - inoyerera nepadiaphragm kuenda kune anode, uko inobatanazve kuti igadzire okisijeni.
Masero emagetsi e-alkaline akakwirira akakodzera kugadzirwa kwehydrogen yakakura. Masero emagetsi e-alkaline akagadzirwa nevamwe vagadziri ane kugona kukuru kwekugadzira hydrogen pa (500 ~ 760Nm3/h), nesimba rinoenderana re2150 ~ 3534kW. Mukuita, kudzivirira kugadzirwa kwemusanganiswa wegasi rinobvira moto, goho rehydrogen rinogumira pa25% kusvika 100% yehuwandu hwakatarwa, huwandu hwemagetsi hunobvumidzwa hunenge 0.4A/cm2, tembiricha yekushanda iri 5 kusvika 100°C, uye kumanikidzwa kwemagetsi kwakanyanya kuri pedyo ne2.5 kusvika 3.0 MPa. Kana kumanikidzwa kwemagetsi kwakanyanya, mari yekudyara inowedzera uye njodzi yekuumbwa kwemusanganiswa wegesi unokuvadza inowedzera zvakanyanya. Pasina chero mudziyo wekuchenesa wekubatsira, kuchena kwehydrogen kunogadzirwa ne-alkaline cell electrolysis kunogona kusvika 99%. Mvura yemagetsi e-alkaline electrolytic cell inofanira kunge yakachena, kuitira kuchengetedza electrode uye kushanda kwakachengeteka, kufambisa mvura kuri pasi pe5S/cm2.
