Txoj kev npaj tseem ceeb rau hydrogen - oxygen generators yog dej electrolysis. Nws txoj hauv kev ua haujlwm suav nrog kev siv qis- qhov hluav taws xob ncaj qha tam sim no rau electrolyze dej (H2O) los ua kom muaj kev sib xyaw ntawm hydrogen thiab oxygen (ie, Brownian gas). Cov txheej txheem no feem ntau yog ua los ntawm cov xov tooj hluav taws xob uas muaj cov khoom siv hluav taws xob xws li potassium hydroxide (KOH) lossis sodium hydroxide (NaOH), thiab muaj lub zog hluav taws xob, hluav taws xob hluav taws xob, roj- cov kua dej sib cais, thiab cov cuab yeej tswj kev nyab xeeb.
Dej electrolysis rau hydrogen ntau lawm suav nrog alkaline electrolysis (AE), proton exchange membrane electrolysis (PEME), thiab khoom oxide electrolysis (SOE). Ntawm cov no, SOE thev naus laus zis siv cov tshuab electrolysis, ua haujlwm ntawm qhov kub thiab txias, thiab theoretically muaj lub zog siab tshaj plaws, tab sis cov thev naus laus zis no tseem nyob rau hauv kev tshawb fawb thiab kev loj hlob theem.
Nyob rau hauv kuv lub teb chaws, kev lag luam daim ntawv thov ntawm dej electrolysis technology yog yus muaj los ntawm AE raws li lub ntsiab txoj kev thiab PEME raws li ib tug ntxiv txoj kev. kuv lub teb chaws tuav ib feem tseem ceeb ntawm lub ntiaj teb no kev ua lag luam rau alkaline electrolysis (AE) hydrogen ntau lawm cov khoom. Nrog rau lub zog tauj dua tshiab-raws li dej electrolysis rau hydrogen ntau lawm yuav tsum dhau los ua txoj hauv kev tseem ceeb yav tom ntej, alkaline dej electrolysis hydrogen ntau lawm thev naus laus zis tab tom txhim kho mus rau qhov muaj peev xwm loj dua. MW-theem PEME hydrogen cov cuab yeej tsim khoom tam sim no tab tom txhim kho thiab xav tias yuav tsim tawm hauv khw hauv 1-2 xyoos.
Hais txog AE hydrogen ntau lawm technology, lub hom phiaj yog los tsim kom muaj zog heev, ntev -lub neej hydrogen thiab oxygen evolution evolution catalytic electrodes, tshiab siab- roj-kuj, tsawg-kuj, thiab ib puag ncig tus phooj ywg daim nyias nyias; optimizing qhov ntws teb qauv tsim ntawm electrolyzers; thiab txhim kho xoom- qhov sib txawv electrolyzers, siab- cov khoom siv hluav taws xob hydrogen ntau lawm, thiab loj- ntsuas hluav taws xob txuas ntxiv hluav taws xob hydrogen. Hais txog PEME hydrogen ntau lawm tshuab, lub hom phiaj yog los txhim kho siab -kev ua tau zoo, qis- muaj nuj nqis- hlau catalysts, siab - durability membrane electrodes, thiab domestically tsim proton pauv membranes; thiab tshawb fawb MW- theem kev sib koom ua ke thiab roj- thev naus laus zis tswj kev tswj cua sov. Thaum lub sij hawm 14th Tsib-Xyoo Plan lub sij hawm, lub hom phiaj yuav yog los txhawb kev ua qauv qhia thiab kev siv loj- muaj peev xwm AE hydrogen ntau lawm technology, tsom rau kev daws cov teeb meem tseem ceeb hauv PEME hydrogen ntau lawm technology, thiab ntxiv dag zog rau kev sib koom ua ke ntawm ob lub thev naus laus zis thiab kev ua qauv qhia ntawm electrohydrogen{{18}.
Dej electrolysis rau hydrogen ntau lawm muaj keeb kwm ntev, thawj zaug pom nyob rau hauv 1800, nrog rau thawj industrial electrolyzer tshwm nyob rau hauv 1902. Cov ntsiab lus tseem ceeb hauv kev txhim kho thev naus laus zis niaj hnub muaj xws li: DuPont txoj kev txhim kho ntawm cov khoom siv hluav taws xob hauv xyoo 1962; NEL txoj kev qhia txog cov uas tsis yog-asbestos membrane alkaline electrolyzers xyoo 1988; thiab kev txhim kho PEM electrolyzer tshuab rau MW- qib khoom siv hluav taws xob txij li xyoo pua 21st.
