Ukadaulo wopangira ma haidrojeni obiriwira ndiwofunikira kwambiri kuti chuma cha haidrojeni chikwaniritsidwe chifukwa, mosiyana ndi imvi ya haidrojeni, haidrojeni wobiriwira satulutsa mpweya wochuluka wa kaboni pakapangidwe kake. Solid oxide electrolytic cell (SOEC), yomwe imagwiritsa ntchito mphamvu zongowonjezwdwa kuti ichotse haidrojeni m'madzi, ikukopa chidwi chifukwa satulutsa zowononga. Pakati pa matekinoloje awa, ma cell otentha olimba a oxide electrolytic ali ndi mwayi wochita bwino kwambiri komanso kuthamanga kwachangu.
Batire ya proton ceramic ndi ukadaulo wotentha kwambiri wa SOEC womwe umagwiritsa ntchito proton ceramic electrolyte kusamutsa ma hydrogen ion mkati mwazinthu. Mabatirewa amagwiritsanso ntchito ukadaulo womwe umachepetsa kutentha kwa ntchito kuchokera ku 700 ° C kapena kupitilira apo mpaka 500 ° C kapena kutsika, potero amachepetsa kukula kwa dongosolo ndi mtengo, ndikuwongolera kudalirika kwanthawi yayitali ndikuchedwetsa kukalamba. Komabe, monga makina ofunikira omwe amapangira sintering protic ceramic electrolytes pa kutentha kochepa kwambiri panthawi yopanga batire sikunafotokozedwe momveka bwino, ndizovuta kupita kumalo ogulitsa.
Gulu lofufuza la Energy Materials Research Center ku Korea Institute of Science and Technology lidalengeza kuti apeza njira iyi ya electrolyte sintering, kukweza kuthekera kwamalonda: ndi m'badwo watsopano wa mabatire a ceramic apamwamba kwambiri omwe sanapezekepo kale. .
Gulu lofufuzalo lidapanga ndikuchita zoyeserera zingapo zamachitsanzo kutengera zomwe zimachitika pakanthawi kochepa pakukula kwa ma electrolyte panthawi ya electrode sintering. Iwo anapeza kwa nthawi yoyamba kuti kupereka pang'ono mpweya sintering wothandiza zakuthupi kuchokera chosakhalitsa electrolyte akhoza kulimbikitsa sintering wa electrolyte. Zothandizira zopangira gasi ndizosowa komanso zovuta kuziwona mwaukadaulo. Chifukwa chake, lingaliro lakuti kachulukidwe ka electrolyte m'maselo a proton ceramic amayamba chifukwa cha vaporizing sintering agent sichinafotokozedwepo. Gulu lofufuzalo linagwiritsa ntchito sayansi yamakompyuta kuti litsimikizire kuti mpweya wa sintering agent ndi kutsimikizira kuti zomwe zimachitika sizimasokoneza mphamvu zapadera zamagetsi a electrolyte. Chifukwa chake, ndizotheka kupanga njira yayikulu yopangira batire ya proton ceramic.
"Ndi phunziroli, tatsala pang'ono kupanga njira yopangira mabatire a proton ceramic," ofufuzawo adatero. Tikukonzekera kuphunzira momwe amapangira mabatire akuluakulu a proton ceramic mtsogolomu. "
