Ukufunyanwa okukhawulezisa ukuthengiswa kweeseli ze-electrolytic ze-solid oxide ukuze kuveliswe i-hydrogen eluhlaza

Itekhnoloji yokuvelisa i-hydrogen eluhlaza iyimfuneko kakhulu ekufezekisweni koqoqosho lwe-hydrogen ekugqibeleni kuba, ngokungafaniyo ne-hydrogen engwevu, i-hydrogen eluhlaza ayivelisi isixa esikhulu se-carbon dioxide ngexesha lokuveliswa kwayo. Iiseli ze-electrolytic ze-oxide eqinileyo (SOEC), ezisebenzisa amandla avuselelekayo ukukhupha i-hydrogen emanzini, zitsala ingqalelo kuba azivelisi ungcoliseko. Phakathi kwezi teknoloji, iiseli ze-electrolytic ze-oxide eqinileyo ezinobushushu obuphezulu zineengenelo zokusebenza kakuhle kunye nesantya sokuvelisa ngokukhawuleza.

Ibhetri ye-proton ceramic yiteknoloji ye-SOEC eshushu kakhulu esebenzisa i-proton ceramic electrolyte ukuhambisa ii-ion ze-hydrogen ngaphakathi kwento ethile. Ezi bhetri zisebenzisa iteknoloji enciphisa amaqondo obushushu okusebenza ukusuka kwi-700 ° C okanye ngaphezulu ukuya kwi-500 ° C okanye ngaphantsi, ngaloo ndlela kunciphisa ubungakanani benkqubo kunye nexabiso, kwaye kuphuculwe ukuthembeka kwexesha elide ngokulibazisa ukuguga. Nangona kunjalo, njengoko indlela ephambili enoxanduva lokusila ii-electrolyte ze-protic ceramic kumaqondo obushushu aphantsi ngexesha lenkqubo yokwenza iibhetri ingachazwanga ngokucacileyo, kunzima ukuya kwinqanaba lokuthengisa.

Iqela lophando kwiZiko loPhando lweZixhobo zaMandla kwiKorea Institute of Science and Technology libhengeze ukuba liyifumene le ndlela yokutshiza i-electrolyte, nto leyo ephakamisa amathuba okuba ithengiswe: sisizukulwana esitsha seebhetri zeseramikhi ezisebenza kakuhle kakhulu ezingazange zifunyanwe ngaphambili.

Iqela lophando liyile kwaye lenze iimvavanyo ezahlukeneyo zemodeli ngokusekelwe kwimpembelelo yesigaba sexesha elifutshane kwi-electrolyte densification ngexesha lokusila kwe-electrode. Bafumanise okokuqala ukuba ukubonelela ngenani elincinci lezinto ezincedisayo zokusila igesi ezivela kwi-electrolyte yexesha elifutshane kunokukhuthaza ukusila kwe-electrolyte. Izincedisi zokusila igesi zinqabile kwaye kunzima ukuzibona ngobuchwephesha. Ke ngoko, ingcamango yokuba ukuxinana kwe-electrolyte kwiiseli ze-proton ceramic kubangelwa yi-agent yokusila ephumayo ayizange icetyiswe. Iqela lophando lisebenzise isayensi yokubala ukuqinisekisa i-arhente yokusila igesi kwaye laqinisekisa ukuba impendulo ayichaphazeli iipropati zombane ezizodwa ze-electrolyte. Ke ngoko, kunokwenzeka ukuyila inkqubo yokuvelisa eyintloko yebhetri ye-proton ceramic.

“Ngeli phononongo, sisondele kakhulu ekuphuhliseni inkqubo ephambili yokuvelisa iibhetri ze-proton ceramic,” batsho abaphandi. Siceba ukufunda inkqubo yokuvelisa iibhetri ze-proton ceramic ezinkulu nezisebenza kakuhle kwixesha elizayo.”
