Ubuchwepheshe bokukhiqiza i-hydrogen eluhlaza buyadingeka kakhulu ekufezeni umnotho we-hydrogen ngoba, ngokungafani ne-hydrogen empunga, i-hydrogen eluhlaza ayikhiqizi inani elikhulu le-carbon dioxide ngesikhathi sokukhiqizwa kwayo. Amaseli e-electrolytic e-solid oxide (SOEC), asebenzisa amandla avuselelekayo ukukhipha i-hydrogen emanzini, adonsela ukunaka ngoba awakhiqizi ukungcola. Phakathi kwalawa ma-technologies, amaseli e-electrolytic e-solid oxide asezingeni lokushisa eliphezulu anezinzuzo zokusebenza kahle okuphezulu kanye nesivinini sokukhiqiza esisheshayo.
Ibhethri le-proton ceramic liwubuchwepheshe be-SOEC obusezingeni eliphezulu obusebenzisa i-electrolyte ye-proton ceramic ukudlulisa ama-ion e-hydrogen ngaphakathi kwento ethile. Lawa mabhethri asebenzisa ubuchwepheshe obunciphisa amazinga okushisa okusebenza kusuka ku-700 ° C noma ngaphezulu kuya ku-500 ° C noma ngaphansi, ngaleyo ndlela kunciphisa usayizi wesistimu kanye nentengo, futhi kuthuthukiswe ukuthembeka kwesikhathi eside ngokubambezela ukuguga. Kodwa-ke, njengoba indlela eyinhloko ebangela ukusha kwama-electrolyte e-protic ceramic emazingeni okushisa aphansi ngesikhathi senqubo yokukhiqiza ibhethri ingakachazwa ngokucacile, kunzima ukuthuthela esigabeni sokuhweba.
Ithimba locwaningo e-Energy Materials Research Center e-Korea Institute of Science and Technology limemezele ukuthi lithole le ndlela yokushisa ama-electrolyte, okwandisa amathuba okuthengiswa: iyisizukulwane esisha samabhethri e-ceramic asebenza kahle kakhulu angakaze atholakale ngaphambili.
Ithimba locwaningo laklama futhi lenza izivivinyo ezahlukahlukene zamamodeli ngokusekelwe emthonjeni wesigaba sesikhashana ekuqineni kwe-electrolyte ngesikhathi sokusikwa kwe-electrode. Bathole okokuqala ukuthi ukunikeza inani elincane lezinto ezisizayo zokusikwa kwegesi ezivela ku-electrolyte yesikhashana kungakhuthaza ukusikwa kwe-electrolyte. Izisiza ezisikwa kwegesi azivamile futhi kunzima ukuzibona ngobuchwepheshe. Ngakho-ke, umbono wokuthi ukuqiniswa kwe-electrolyte kumaseli e-proton ceramic kubangelwa yi-agent yokusikwa kwegesi ephefumulayo awukaze uphakanyiswe. Ithimba locwaningo lisebenzise isayensi yokubala ukuqinisekisa i-agent yokusikwa kwegesi futhi laqinisekisa ukuthi ukusabela akuphazamisi izakhiwo zikagesi ezihlukile ze-electrolyte. Ngakho-ke, kungenzeka ukuklama inqubo yokukhiqiza eyinhloko yebhethri le-proton ceramic.
"Ngalolu cwaningo, sesisondele kakhulu ekuthuthukiseni inqubo eyinhloko yokukhiqiza amabhethri e-proton ceramic," kusho abacwaningi. Sihlela ukutadisha inqubo yokukhiqiza amabhethri e-proton ceramic asendaweni enkulu, asebenza kahle kakhulu esikhathini esizayo."
