Kupeza komwe kumathandizira kugulitsa kwa maselo olimba a electrolytic oxide kuti apange haidrojeni wobiriwira

Ukadaulo wopanga haidrojeni wobiriwira ndi wofunikira kwambiri kuti chuma cha haidrojeni chikwaniritsidwe chifukwa, mosiyana ndi haidrojeni yoyera, haidrojeni wobiriwira sapanga mpweya wambiri wa carbon dioxide panthawi yopangidwa. Maselo a electrolytic a oxide olimba (SOEC), omwe amagwiritsa ntchito mphamvu zongowonjezwdwanso kutulutsa haidrojeni m'madzi, akukopa chidwi chifukwa sapanga zoipitsa. Pakati pa matekinoloje awa, maselo a electrolytic a oxide olimba otentha kwambiri ali ndi ubwino wochita bwino kwambiri komanso kuthamanga kwa kupanga.

Batire ya proton ceramic ndi ukadaulo wa SOEC wotentha kwambiri womwe umagwiritsa ntchito electrolyte ya proton ceramic kusamutsa ma hydrogen ions mkati mwa chinthu. Mabatirewa amagwiritsanso ntchito ukadaulo womwe umachepetsa kutentha kwa ntchito kuyambira 700 ° C kapena kupitirira apo mpaka 500 ° C kapena kutsika, motero amachepetsa kukula kwa makina ndi mtengo, ndikukweza kudalirika kwa nthawi yayitali pochedwetsa ukalamba. Komabe, popeza njira yofunika kwambiri yochepetsera ma electrolyte a protic ceramic pa kutentha kochepa panthawi yopanga mabatire sinafotokozedwe bwino, n'zovuta kupita ku gawo logulitsa.

Gulu lofufuza ku Energy Materials Research Center ku Korea Institute of Science and Technology lalengeza kuti lapeza njira yoyeretsera ma electrolyte, zomwe zawonjezera kuthekera kogulitsa: ndi mbadwo watsopano wa mabatire a ceramic ogwira ntchito bwino omwe sanapezekepo kale.

Gulu lofufuza linapanga ndikuchita zoyeserera zosiyanasiyana za chitsanzo kutengera momwe gawo la transient phase limakhudzira kuchuluka kwa electrolyte panthawi yopopera ma electrode. Anapeza koyamba kuti kupereka zinthu zochepa zothandizira popopera ma gasi kuchokera ku electrolyte ya transient kungathandize popopera ma electrolyte. Zothandizira popopera ma gasi ndizosowa ndipo n'zovuta kuziona mwaukadaulo. Chifukwa chake, lingaliro lakuti kuchuluka kwa ma electrolyte m'maselo a ceramic a proton kumayambitsidwa ndi chopopera ma gasi sichinaperekedwepo. Gulu lofufuza linagwiritsa ntchito sayansi ya makompyuta kuti litsimikizire chopopera ma gasi ndipo linatsimikizira kuti zomwe zimachitika sizikusokoneza mphamvu zamagetsi zapadera za electrolyte. Chifukwa chake, n'zotheka kupanga njira yopangira batri ya ceramic ya proton.

"Ndi kafukufukuyu, tayandikira kwambiri kupanga njira yopangira mabatire a proton ceramic," ofufuzawo adatero. Tikukonzekera kuphunzira njira yopangira mabatire a proton ceramic akuluakulu komanso ogwira ntchito bwino mtsogolo."
