Cov thev naus laus zis tsim cov hydrogen ntsuab yog qhov tsim nyog rau qhov kawg ntawm kev ua tiav ntawm kev lag luam hydrogen vim tias, tsis zoo li grey hydrogen, hydrogen ntsuab tsis tsim cov pa roj carbon dioxide ntau thaum nws tsim tawm. Cov hlwb electrolytic oxide khoom (SOEC), uas siv lub zog rov ua dua tshiab los rho tawm hydrogen ntawm dej, tau nyiam mloog vim tias lawv tsis tsim cov pa phem. Ntawm cov thev naus laus zis no, cov hlwb electrolytic oxide khoom kub siab muaj qhov zoo ntawm kev ua haujlwm zoo thiab kev tsim khoom sai.
Lub roj teeb proton ceramic yog ib qho thev naus laus zis SOEC kub siab uas siv cov electrolyte proton ceramic los hloov cov hydrogen ions hauv ib yam khoom. Cov roj teeb no kuj siv cov thev naus laus zis uas txo qhov kub ua haujlwm ntawm 700 ° C lossis siab dua mus rau 500 ° C lossis qis dua, yog li txo qhov loj me thiab tus nqi ntawm lub kaw lus, thiab txhim kho kev ntseeg siab mus sij hawm ntev los ntawm kev ncua kev laus. Txawm li cas los xij, vim tias lub tshuab tseem ceeb uas ua rau sintering protic ceramic electrolytes ntawm qhov kub qis thaum lub sijhawm tsim roj teeb tsis tau txhais meej, nws nyuaj rau txav mus rau theem kev lag luam.
Cov pab pawg tshawb fawb ntawm Lub Chaw Tshawb Fawb Txog Cov Khoom Siv Zog ntawm Korea Institute of Science and Technology tau tshaj tawm tias lawv tau tshawb pom cov txheej txheem electrolyte sintering no, ua rau muaj peev xwm ua lag luam: nws yog ib tiam tshiab ntawm cov roj teeb ceramic ua haujlwm siab uas tsis tau pom dua ua ntej.
Cov pab pawg tshawb fawb tau tsim thiab ua ntau yam kev sim ua qauv raws li qhov cuam tshuam ntawm theem transient rau electrolyte densification thaum lub sijhawm electrode sintering. Lawv pom thawj zaug tias kev muab me me ntawm cov khoom siv gaseous sintering auxiliary los ntawm transient electrolyte tuaj yeem txhawb kev sintering ntawm electrolyte. Cov roj sintering auxiliaries tsis tshua muaj thiab nyuaj rau saib xyuas kev siv tshuab. Yog li ntawd, qhov kev xav tias electrolyte densification hauv proton ceramic cells yog tshwm sim los ntawm tus neeg sawv cev vaporizing sintering yeej tsis tau raug thov. Pab pawg tshawb fawb tau siv kev tshawb fawb computational los txheeb xyuas tus neeg sawv cev gaseous sintering thiab lees paub tias qhov kev tshuaj tiv thaiv tsis cuam tshuam rau cov khoom hluav taws xob tshwj xeeb ntawm electrolyte. Yog li ntawd, nws muaj peev xwm tsim cov txheej txheem tsim khoom tseem ceeb ntawm proton ceramic roj teeb.
"Nrog rau txoj kev tshawb fawb no, peb tau ib kauj ruam ze rau kev tsim cov txheej txheem tsim khoom tseem ceeb rau cov roj teeb proton ceramic," cov kws tshawb fawb hais. Peb npaj yuav kawm txog cov txheej txheem tsim khoom ntawm cov roj teeb proton ceramic loj, ua haujlwm tau zoo yav tom ntej.
