Ubuchwepheshe bokukhiqiza i-hydrogen eluhlaza buyadingeka ngokuphelele ukuze ekugcineni kufezeke umnotho we-hydrogen ngoba, ngokungafani ne-hydrogen empunga, i-hydrogen eluhlaza ayikhiqizi inani elikhulu lesikhutha ngesikhathi sokukhiqizwa kwayo. Amaseli e-Solid oxide electrolytic (SOEC), asebenzisa amandla avuselelekayo ukuze akhiphe i-hydrogen emanzini, adonsela ukunaka ngoba awakhiqizi izinto ezingcolisayo. Phakathi kwalobu buchwepheshe, izinga lokushisa eliphezulu eliqinile lamaseli e-electrolytic electrolytic anezinzuzo zokusebenza kahle okuphezulu kanye nesivinini sokukhiqiza esisheshayo.
Ibhethri ye-proton ceramic ubuchwepheshe obusezingeni eliphezulu be-SOEC obusebenzisa i-proton ceramic electrolyte ukudlulisa ama-ion e-hydrogen ngaphakathi kwempahla. Lawa mabhethri aphinde asebenzise ubuchwepheshe obunciphisa amazinga okushisa okusebenza ukusuka ku-700 ° C noma ngaphezulu kuya ku-500 ° C noma ngaphansi, ngaleyo ndlela ehlise usayizi wesistimu nenani, futhi athuthukise ukwethembeka kwesikhathi eside ngokubambezela ukuguga. Kodwa-ke, njengoba indlela eyinhloko enesibopho sokufaka ama-electrolyte e-protic ceramic emazingeni okushisa aphansi uma kuqhathaniswa nenqubo yokukhiqiza ibhethri ingachazwanga ngokucacile, kunzima ukuya esigabeni sokuthengisa.
Ithimba labacwaningi e-Energy Materials Research Centre e-Korea Institute of Science and Technology limemezele ukuthi bathole le nqubo yokufaka i-electrolyte sintering, iphakamisa amathuba okuthengisa: isizukulwane esisha samabhethri e-ceramic asebenza kahle kakhulu angakaze atholwe ngaphambili. .
Ithimba locwaningo laklama futhi lenza izivivinyo zamamodeli ahlukahlukene ngokusekelwe kumphumela wesigaba sesikhashana ekugxilweni kwe-electrolyte ngesikhathi sokucwiliswa kwama-electrode. Bathole ngokokuqala ngqa ukuthi ukuhlinzeka ngenani elincane le-gaseous sintering material esisizayo kusukela ku-electrolyte yesikhashana kungakhuthaza ukucwiliswa kwe-electrolyte. Izinsiza zokushiswa kwegesi azivamile futhi kunzima ukuziqaphela ngokobuchwepheshe. Ngakho-ke, i-hypothesis yokuthi ukuminyana kwe-electrolyte kumaseli e-proton ceramic kubangelwa i-agent sintering ehwamukayo akukaze kuphakanyiswe. Ithimba locwaningo lisebenzise isayensi yekhompyutha ukuze liqinisekise i-ejenti ye-gaseous sintering futhi laqinisekisa ukuthi ukusabela akuphazamisi izici ezihlukile zikagesi ze-electrolyte. Ngakho-ke, kungenzeka ukuklama inqubo yokukhiqiza eyinhloko yebhethri ye-proton ceramic.
"Ngalolu cwaningo, siyisinyathelo esisodwa esiseduze nokuthuthukisa inqubo yokukhiqiza eyinhloko yamabhethri e-proton ceramic," kusho abacwaningi. Sihlela ukutadisha inqubo yokukhiqiza amabhethri e-ceramic e-proton asebenza kahle kakhulu endaweni enkulu esikhathini esizayo."
