Itekhnoloji yokuvelisa i-hydrogen eluhlaza iyimfuneko ngokupheleleyo ekufezekiseni uqoqosho lwe-hydrogen ekugqibeleni, kuba, ngokungafaniyo ne-hydrogen engwevu, i-hydrogen eluhlaza ayivelisi isixa esikhulu se-carbon dioxide ngexesha lemveliso yayo. Iiseli ze-Solid oxide electrolytic (SOEC), ezisebenzisa amandla ahlaziyekayo ukukhupha i-hydrogen emanzini, zitsala ingqalelo kuba azivelisi izinto ezingcolisayo. Phakathi kwezi teknoloji, iiseli ze-electrolytic eziqinileyo zobushushu obuphezulu zineenzuzo zokusebenza okuphezulu kunye nesantya sokuvelisa ngokukhawuleza.
Ibhetri ye-ceramic yeproton yitekhnoloji yobushushu obuphezulu be-SOEC esebenzisa i-proton ceramic electrolyte ukuhambisa i-ion hydrogen ngaphakathi kwesixhobo. Ezi bhetri zikwasebenzisa iteknoloji enciphisa ubushushu bokusebenza ukusuka kwi-700 ° C okanye ngaphezulu ukuya kwi-500 ° C okanye ngaphantsi, ngaloo ndlela inciphisa ubungakanani benkqubo kunye nexabiso, kunye nokuphucula ukuthembeka kwexesha elide ngokulibazisa ukuguga. Nangona kunjalo, njengoko indlela ephambili enoxanduva lokutshisa i-electrolyte ye-ceramic ye-sintering kumaqondo aphantsi kakhulu ngexesha lenkqubo yokuvelisa ibhetri ayichazwanga ngokucacileyo, kunzima ukuya kwinqanaba lokuthengisa.
Iqela lophando kwiZiko loPhando lweMathiriyeli ye-Energy kwiZiko laseKorea leSayensi kunye neTekhnoloji libhengeze ukuba liyifumene le ndlela yokwenza i-electrolyte sintering, iphakamisa amathuba okurhweba: sisizukulwana esitsha seebhetri ze-ceramic ezisebenzayo ezingazange zifunyanwe ngaphambili. .
Iqela lophando liye layila kwaye lenza imifuniselo eyahlukeneyo yemodeli esekwe kwisiphumo sesigaba esidlulayo kwi-electrolyte densification ngexesha le-electrode sintering. Baye bafumanisa okokuqala ukuba ukubonelela ngexabiso elincinci le-gaseous sintering encedisayo evela kwi-electrolyte edlulayo inokukhuthaza i-sintering ye-electrolyte. Abancedisi bokutshisa igesi banqabile kwaye kunzima ukuziqwalasela ngokobugcisa. Ke ngoko, i-hypothesis yokuba i-electrolyte densification kwiiseli ze-ceramic zeproton ibangelwa yi-agent ye-vaporizing sintering ayizange icetywe. Iqela lophando lisebenzise isayensi ye-computational ukuqinisekisa i-agent ye-gaseous sintering kwaye yaqinisekisa ukuba ukusabela akuphazamisi iimpawu zombane ezizodwa ze-electrolyte. Ke ngoko, kunokwenzeka ukuyila eyona nkqubo yokuvelisa ibhetri ye-proton ceramic.
“Ngolu phononongo, silinyathelo elinye elikufutshane ekuphuhliseni eyona nkqubo yokuvelisa iibhetri zeproton ceramic,” batsho abaphandi. Siceba ukufunda inkqubo yokwenziwa kwendawo enkulu, iibhetri ze-ceramic ezisebenza kakuhle kakhulu kwixa elizayo. "
