Ubuvumbuzi bwihutisha ubucuruzi bwa selile ikomeye ya okiside electrolytique kugirango ikore hydrogene yicyatsi

Ikoranabuhanga rya hydrogène y’icyatsi rirakenewe rwose kugirango amaherezo yubukungu bwa hydrogène kuko, bitandukanye na hydrogène yumukara, hydrogène yicyatsi ntabwo itanga karuboni nyinshi ya karubone mugihe ikora. Ingirabuzimafatizo zikomeye za electrolytike (SOEC), zikoresha ingufu zishobora gukura hydrogène mu mazi, zirimo gukurura abantu kuko zidatanga umwanda. Muri ubwo buryo bwikoranabuhanga, ubushyuhe bwo hejuru bwa oxyde electrolytike selile zifite ibyiza byo gukora neza kandi byihuse.

Batiyeri ya proton ceramic nubushyuhe bwo hejuru bwa tekinoroji ya SOEC ikoresha proton ceramic electrolyte kugirango yimure hydrogene ion mubikoresho. Izi bateri kandi zikoresha ikoranabuhanga rigabanya ubushyuhe bwimikorere kuva kuri 700 ° C cyangwa hejuru ya 500 ° C cyangwa munsi yayo, bityo bikagabanya ingano ya sisitemu nigiciro, no kuzamura ubwizerwe bwigihe kirekire mugutinda gusaza. Nyamara, nkuburyo bwingenzi bushinzwe gucumura protic ceramic electrolytite ku bushyuhe buke ugereranije mugihe cyo gukora bateri ntabwo byasobanuwe neza, biragoye kwimuka mubyiciro byubucuruzi.

Itsinda ry’ubushakashatsi mu kigo cy’ubushakashatsi ku mbaraga z’ingufu mu kigo cy’ubumenyi n’ikoranabuhanga cya Koreya cyatangaje ko bavumbuye ubu buryo bwo gucumura electrolyte, bigatuma bishoboka ko hajyaho ubucuruzi: ni igisekuru gishya cya bateri y’ubutaka bukora neza butavumbuwe mbere .

Itsinda ry’ubushakashatsi ryateguye kandi rikora ubushakashatsi butandukanye bwikitegererezo bushingiye ku ngaruka zicyiciro cyinzibacyuho kuri densifike ya electrolyte mugihe cyo gucumura electrode. Basanze ku nshuro ya mbere ko gutanga umubare muto wibikoresho bya gaze ya sinteri yingirakamaro biva muri electrolyte yinzibacyuho bishobora guteza imbere gucumura kwa electrolyte. Abafasha bokoresha gaz ntibisanzwe kandi biragoye kubyitegereza mubuhanga. Kubwibyo rero, hypothesis ivuga ko densifike ya electrolyte muri selile ceramic selile iterwa numusemburo wumuyaga wumuyaga ntiwigeze utangwa. Itsinda ry’ubushakashatsi ryifashishije siyanse yo kubara kugira ngo rigenzure gaze ya sinte kandi yemeza ko iyo myitwarire idahungabanya imiterere yihariye y’amashanyarazi ya electrolyte. Kubwibyo, birashoboka gushushanya inzira yibanze yo gukora ya bateri ya proton ceramic.

Abashakashatsi bagize bati: "Hamwe n'ubu bushakashatsi, twegereye intambwe imwe yo guteza imbere inzira nyamukuru yo gukora za bateri za proton ceramic". Turateganya kwiga uburyo bwo gukora inganda za bateri nini, zifite ingufu nyinshi za proton ceramic mu gihe kiri imbere. "
