Green hydrogen ntau lawm tshuab yog qhov tsim nyog rau qhov kawg ntawm kev lag luam hydrogen vim tias, tsis zoo li grey hydrogen, ntsuab hydrogen tsis tsim cov pa roj carbon dioxide ntau thaum nws tsim. Solid oxide electrolytic cells (SOEC), uas siv lub zog tauj dua tshiab los rho hydrogen los ntawm dej, yog qhov nyiam vim lawv tsis tsim cov pa phem. Ntawm cov thev naus laus zis no, cov khoom siv hluav taws xob kub kub oxide electrolytic muaj qhov zoo ntawm kev ua haujlwm siab thiab kev ua haujlwm ceev ceev.
Lub roj teeb proton ceramic yog qhov kub-kub SOEC thev naus laus zis uas siv cov proton ceramic electrolyte hloov hydrogen ions hauv cov khoom siv. Cov roj teeb no kuj siv cov cuab yeej siv uas txo cov kev khiav hauj lwm kub ntawm 700 ° C los yog siab dua mus rau 500 ° C los yog qis dua, yog li txo qhov system loj thiab tus nqi, thiab txhim kho kev ntseeg tau ntev los ntawm kev ncua kev laus. Txawm li cas los xij, raws li lub luag haujlwm tseem ceeb ntawm sintering protic ceramic electrolytes ntawm qhov kub thiab txias thaum lub sijhawm tsim cov roj teeb tsis tau txhais meej meej, nws nyuaj rau kev txav mus rau theem kev lag luam.
Pab neeg tshawb fawb ntawm Lub Chaw Tshawb Fawb Txog Hluav Taws Xob ntawm Kaus Lim Kauslim Lub Tsev Haujlwm Saib Xyuas Kev Tshawb Fawb thiab thev naus laus zis tau tshaj tawm tias lawv tau tshawb pom lub tshuab electrolyte sintering no, ua rau muaj peev xwm ua lag luam: nws yog lub cim tshiab ntawm cov roj teeb ceramic uas tsis tau pom dua ua ntej. .
Pab neeg tshawb fawb tau tsim thiab ua ntau yam kev sim ua qauv raws li qhov cuam tshuam ntawm cov theem ntawm cov electrolyte densification thaum electrode sintering. Lawv pom thawj zaug uas muab me me ntawm gaseous sintering auxiliary khoom los ntawm cov electrolyte ib ntus tuaj yeem txhawb kev sintering ntawm electrolyte. Gas sintering auxiliaries yog tsawg thiab nyuaj rau kev soj ntsuam technically. Yog li ntawd, lub hypothesis hais tias cov electrolyte densification nyob rau hauv proton ceramic hlwb yog tshwm sim los ntawm cov vaporizing sintering tus neeg saib xyuas yeej tsis tau npaj. Pab neeg tshawb fawb tau siv cov kev tshawb fawb los txheeb xyuas cov neeg sawv cev gaseous sintering thiab paub tseeb tias cov tshuaj tiv thaiv tsis cuam tshuam cov khoom hluav taws xob tshwj xeeb ntawm electrolyte. Yog li, nws muaj peev xwm tsim cov txheej txheem tsim khoom tseem ceeb ntawm proton ceramic roj teeb.
"Nrog rau txoj kev tshawb no, peb yog ib kauj ruam ze dua los tsim cov txheej txheem tsim khoom tseem ceeb rau proton ceramic roj teeb," cov kws tshawb fawb tau hais. Peb npaj los kawm txog cov txheej txheem tsim khoom ntawm thaj chaw loj, ua haujlwm tau zoo proton ceramic roj teeb yav tom ntej. "
