Green hydrogen yekugadzira tekinoroji inodiwa zvachose kuti hupfumi hwehydrogen huzozadzikiswa nekuti, kusiyana negrey hydrogen, girini haidhirojeni haiburitse huwandu hwekabhoni dhaokisaidi panguva yekugadzirwa kwayo. Solid oxide electrolytic masero (SOEC), ayo anoshandisa simba rinodzokororwa kubvisa haidrojeni kubva mumvura, ari kukwezva kutarisa nekuti haaburitse zvinosvibisa. Pakati peaya matekinoroji, tembiricha yakanyanya solid oxide electrolytic maseru ane zvakanakira kushanda kwakanyanya uye nekukurumidza kugadzira kukurumidza.
Iyo proton ceramic bhatiri ndeyepamusoro-tembiricha yeSOEC tekinoroji inoshandisa proton ceramic electrolyte kuendesa hydrogen ions mukati mechinhu. Mabhatiri aya anoshandisawo tekinoroji inoderedza tembiricha yekushanda kubva pa700 ° C kana kukwira kusvika pa500 ° C kana kudzikira, nokudaro ichideredza saizi yehurongwa nemutengo, nekuvandudza kuvimbika kwenguva refu nekunonoka kuchembera. Nekudaro, seyakakosha nzira inokonzeresa sintering protic ceramic electrolytes panguva yakaderera tembiricha panguva yekugadzira bhatiri maitiro asina kunyatsotsanangurwa, zvakaoma kutamira kune yekutengeserana nhanho.
Boka rekutsvagisa paEnergy Materials Research Center kuKorea Institute of Science and Technology rakazivisa kuti vakawana iyi electrolyte sintering mechanism, ichisimudza mukana wekutengesa: ichizvarwa chitsva chepamusoro-inoshanda mabhatiri eceramic asina kuwanikwa kare. .
Chikwata chekutsvagisa chakagadzira uye chakaita bvunzo dzakasiyana siyana zvichienderana nemhedzisiro yechikamu chenguva pfupi pane electrolyte densification panguva ye electrode sintering. Vakaona kekutanga kuti kupa shoma shoma gaseous sintering ebetsero zvinhu kubva pfupi electrolyte anogona kusimudzira sintering ye electrolyte. Gasi sintering yekubatsira ishoma uye yakaoma kuona nehunyanzvi. Naizvozvo, fungidziro yekuti iyo electrolyte densification muproton ceramic masero inokonzerwa neiyo vaporizing sintering agent haina kumbobvira yataurwa. Chikwata chekutsvagisa chakashandisa sainzi yekombuta kuratidza iyo gaseous sintering agent uye yakasimbisa kuti kuita hakukanganisi yakasarudzika magetsi emagetsi e electrolyte. Naizvozvo, zvinokwanisika kugadzira iyo yakakosha yekugadzira maitiro eproton ceramic bhatiri.
"Nechidzidzo ichi, isu tiri nhanho imwe padyo nekugadzira nzira yekugadzira mabhatiri eproton ceramic," vaongorori vakadaro. Isu tinoronga kudzidza maitiro ekugadzira mabhatiri eproton ceramic mune ramangwana. "
