Ubuvumbuzi bwihutisha ubucuruzi bw'uturemangingo tw'amashanyarazi ya oxide ikomeye kugira ngo hakorwe hydrogen y'icyatsi kibisi

Ikoranabuhanga ryo gukora hydrogen y’icyatsi kibisi ni ngombwa cyane kugira ngo ubukungu bwa hydrogen bugerweho kuko, bitandukanye na hydrogen y’ikijuju, hydrogen y’icyatsi kibisi ntitanga gazi karuboni nyinshi mu gihe cyo kuyikora. Uturemangingo tw’amashanyarazi twa oxide ikomeye (SOEC), dukoresha ingufu zisubiramo mu gukura hydrogen mu mazi, turimo gukurura abantu kuko tudakora imyanda. Muri ubwo ikoranabuhanga, uturemangingo tw’amashanyarazi twa oxide ikomeye mu bushyuhe bwinshi dufite ibyiza byo gukora neza cyane no kwihuta mu kuyikora.

Bateri ya proton ceramic ni ikoranabuhanga rya SOEC rikoresha ubushyuhe bwinshi rikoresha electrolyte ya proton ceramic mu kohereza iyoni za hydrogen mu bikoresho. Izi bateri kandi zikoresha ikoranabuhanga rigabanya ubushyuhe bw'imikorere kuva kuri 700 ° C cyangwa hejuru yayo kugeza kuri 500 ° C cyangwa hasi yayo, bityo bikagabanya ingano n'igiciro bya sisitemu, kandi bikanoza ubwizigirwa bw'igihe kirekire binyuze mu gutinda gusaza. Ariko, kubera ko uburyo bw'ingenzi butuma electrolyte za protic ceramic zishwanyagurika ku bushyuhe buke mu gihe cyo gukora bateri butarasobanuka neza, biragoye kwimukira mu cyiciro cyo kugurisha.

Itsinda ry’abashakashatsi bo mu Kigo cy’Ubushakashatsi ku Bikoresho by’Ingufu mu Kigo cy’Ubumenyi n’Ikoranabuhanga cya Koreya ryatangaje ko bavumbuye ubu buryo bwo gutwika electrolyte, byongera amahirwe yo gucuruzwa: ni ubwoko bushya bwa bateri za keramike zikora neza cyane zitari zavumburwa mbere.

Itsinda ry’ubushakashatsi ryakoze kandi rikora igerageza ry’icyitegererezo gitandukanye rishingiye ku ngaruka z’impinduka z’igihe gito ku kwiyongera kwa electrolyte mu gihe cyo gushonga kwa electrode. Basanze ku nshuro ya mbere ko gutanga ingano nto y’ibikoresho by’inyongera biva muri electrolyte y’igihe gito bishobora guteza imbere gushonga kwa electrolyte. Ibikoresho by’inyongera biva muri gazi ni bike cyane kandi biragoye kubireba mu buryo bwa tekiniki. Kubwibyo, igitekerezo cy’uko gushonga kwa electrolyte mu turemangingo twa porotoni biterwa n’ikintu gihumanya ikirere nticyigeze gitangwa. Itsinda ry’ubushakashatsi ryakoresheje siyansi y’ikoranabuhanga kugira ngo ryemeze igikoresho gihumanya ikirere kandi ryemeza ko igisubizo kitabangamira imiterere yihariye y’amashanyarazi ya electrolyte. Kubwibyo, birashoboka gushushanya inzira nyamukuru yo gukora bateri ya porotoni.

Abashakashatsi bagize bati: “Turi hafi yo guteza imbere inzira y’ingenzi yo gukora bateri za proton ceramic.” Turateganya kwiga inzira yo gukora bateri za proton ceramic mu busitani bunini kandi bukora neza cyane mu gihe kizaza.”
