HKU timu inobudirira kugadzira "simbi isina tsvina yekugadzira hydrogen"

Stainless simbi ndiyo chidimbu cheStainless acid-resistant simbi. Mhando dzeSimbi dzinoshingirira kune zvisina kusimba zvinoodza media zvakaita semhepo, chiutsi, uye mvura kana zvisina tsvina dzinodaidzwa kuti simbi isina tsvina. Izwi rekuti "stainless simbi" haringorevi rudzi rumwe chete rwesimbi isina tsvina, asi rinoreva anopfuura zana maindasitiri esimbi asina tsvina, imwe neimwe inogadzirwa kuti iite zvakanaka mundima yayo yekushandisa.

Simbi isina tsvina chinhu chakakosha alloy zvinhu izvo zvikuru zvikamu zvinosanganisira iron, chromium, nickel, molybdenum uye zvimwe zvinhu. Mareshiyo akasiyana uye akasiyana ari mukati mezvinhu izvi zvinotarisa zvimiro uye mashandisirwo esimbi isina tsvina. Iye zvino ndava kukuzivisai rudzi rutsva rwesimbi yakakosha.

Chikwata chaPurofesa Huang Mingxin kubva kuDhipatimendi reMechanical Engineering yeYunivhesiti yeHong Kong yakabudirira kugadzira "simbi isina tsvina yekugadzirwa kwehydrogen". Mvura yayo yemunyu inodzivirira uye kugadzirwa kwehydrogen yakakwira zvakanyanya kune yechinyakare simbi isina tsvina. Kana ikashandiswa mumaindasitiri, ichaderedza zvakanyanya mutengo wekugadzirwa kwehydrogen ne electrolyzing mvura yegungwa, nokudaro ichipa haidrojeni Inobatsira mukusimudzira indasitiri yemagetsi uye nekuzadzikiswa kwekabhoni peak uye kusarerekera kabhoni.

Zvinonzwisiswa kuti iko zvino kushandiswa kwemvura yegungwa yakasvibiswa kana acidic mhinduro kugadzira haidrojeni kazhinji inoshandisa inodhura goridhe-yakaputirwa kana platinamu-yakapfatwa yakachena titanium zvinhu se electrolytic cell structural components. Panguva ino, mutengo wakazara wePEM electrolyzer michina ine simba regumi MW ingangoita HK$17.8 miriyoni, iyo iyo mutengo wezvikamu zvezvimiro ungakwira kusvika pa53%. Simbi itsva isina tsvina yakagadziridzwa nechikwata chaProfessor Huang Mingxin inotarisirwa kudzikisa mutengo wezvigadzirwa zvezvivakwa kanosvika makumi mana.

"Simbi isina tsvina yekugadzirwa kwehydrogen" inogona kuburitsa hydrogen mumvura ine munyu, uye inogonawo kutsiva yakachena titanium zvimiro zvemukati, zvichiita kuti mutengo wezvigadzirwa zvemagadzirirwo udhure kakawanda, zvichipa tekinoroji inogoneka uye inobatsira mune zvehupfumi yekugadzira hydrogen yemvura yegungwa ichiri mumhepo. tsvakurudzo uye danho rekusimudzira. s mhinduro.

Irizvino bepa rekutsvagisa rakaburitswa muMaterials Nhasi. "Simbi isina simbi yekugadzirwa kwehydrogen" iri kunyorera marezenisi emarudzi akawanda, maviri acho akatenderwa, uye makambani emagetsi ehydrogen aratidza kufarira kubatana.
