Ithimba le-HKU lithuthukisa ngempumelelo "insimbi engagqwali yokukhiqiza i-hydrogen"

Insimbi engagqwali isifinyezo sensimbi engagqwali engamelana ne-asidi. Izinhlobo zensimbi ezimelana nemithombo yemali ebolayo ebuthakathaka njengomoya, isitimu, namanzi noma ezingenasici zibizwa ngokuthi insimbi engagqwali. Igama elithi "insimbi engagqwali" alibhekiseli nje ohlotsheni olulodwa lwensimbi engagqwali, kodwa libhekisela ezinsimbi zensimbi ezingenasici zezimboni ezingaphezu kwekhulu, ngayinye ethuthukiswayo ukuze ibe nokusebenza kahle emkhakheni wayo wesicelo esithile.

Insimbi engagqwali iyi-alloy material ekhethekile izingxenye zayo eziyinhloko zihlanganisa insimbi, i-chromium, i-nickel, i-molybdenum nezinye izakhi. Izilinganiso ezihlukene nokuqukethwe okuhlukile kwalezi zakhi kunquma izakhiwo nokusetshenziswa kwensimbi engagqwali. Manje ngizokwethula ohlotsheni olusha lwensimbi engagqwali ekhethekile.

Ithimba likaSolwazi Huang Mingxin ovela eMnyangweni Wezobunjiniyela Bemishini eNyuvesi yaseHong Kong lenze ngempumelelo "insimbi engagqwali yokukhiqiza i-hydrogen". Ukumelana nokugqwala kwamanzi anosawoti kanye nokusebenza kokukhiqizwa kwe-hydrogen kuphakeme kakhulu kunensimbi engagqwali yendabuko. Uma isetshenziswa ezimbonini, izonciphisa kakhulu izindleko zokukhiqizwa kwe-hydrogen ngokufaka i-electrolyzing emanzini olwandle, ngaleyo ndlela inikeze i-hydrogen Faka isandla ekuthuthukisweni kwemboni yamandla kanye nokugcwaliseka kwe-carbon peak kanye nokungathathi hlangothi kwe-carbon.

Kuyaqondakala ukuthi ukusetshenziswa kwamanje kwamanzi olwandle akhishwe usawoti kasawoti noma izixazululo ezine-acidic ukukhiqiza i-hydrogen ngokuvamile kusebenzisa izinto ezihlanzekile ze-titanium ezicwebezelisiwe ngegolide ezibizayo noma zeplatinamu njengezingxenye zesakhiwo seseli ye-electrolytic. Kulesi sigaba, izindleko zizonke zemishini ye-PEM electrolyzer enamandla angu-10 MW cishe ilinganiselwa ku-HK$17.8 million, ingxenye yayo yezindleko zezingxenye zesakhiwo ingaba phezulu ngokufinyelela ku-53%. Insimbi entsha engagqwali eyakhiwe ithimba likaSolwazi Huang Mingxin kulindeleke ukuthi yehlise izindleko zezinto zokwakha cishe izikhathi ezingama-40.

"Insimbi engagqwali yokukhiqiza i-hydrogen" ingakhiqiza ngokuqondile i-hydrogen emanzini anosawoti, futhi ingashintsha izingxenye zesakhiwo se-titanium ehlanzekile, okwenza izindleko zezingxenye zesakhiwo zibe zishibhile izikhathi eziningi, zinikeze ubuchwepheshe bokukhiqiza amanzi olwandle e-hydrogen obungenzeka futhi obuzuzisa ngokomnotho obusesekhona isigaba socwaningo nentuthuko. s isixazululo.

Iphepha lamanje locwaningo lishicilelwe ku-Materials Today. "Insimbi engagqwali yokukhiqizwa kwe-hydrogen" ifaka isicelo samalungelo obunikazi avela emazweni amaningi, amabili awo agunyaziwe, futhi izinkampani zamandla e-hydrogen ziye zazwakalisa intshisekelo yokubambisana.
