In daim nyias nyias pauv protonLub roj cell, qhov catalytic oxidation ntawm protons yog cathode sab hauv daim nyias nyias, tib lub sijhawm, lub anode ntawm electrons txav mus rau cathode los ntawm ib lub voj voog sab nraud, qhov zoo ua ke nrog hluav taws xob thiab cathodic txo cov pa oxygen ntawm qhov chaw ntawm cov dej tsim tawm, lub zog tsim los ntawm hluav taws xob los ntawm ib lub voj voog sab nraud conduction. Hauv cov roj cell membrane electrode thiab qhov ua tau zoo yog qhov tseem ceeb, thiab kev ua haujlwm siab proton yog ib qho tseem ceeb ntawm cov khoom siv proton pauv membrane. Proton pauv membrane feem ntau yog tsim los ntawm cov qauv sib cais zoo ntawm hydrophobic thiab hydrophilic, cov qauv hydrophobic kom tsis txhob nqus dej ntau dhau, ua rau daim nyias nyias o qis dua, tswj kev ruaj khov ntawm daim nyias nyias; Hydrophilic pawg ntawm sulfate yog conducting channel muab txaus, tuaj yeem yog protons los ntawm anode mus rau cathode, roj roj sib tov tib lub sijhawm.
Cov roj teeb uas siv rau hauv cov roj teeb uas pauv proton thaum ntxov muaj qhov tsis zoo ntawm tus nqi siab thiab lub neej luv luv vim yog siv cov roj teeb uas muaj sulfonated polystyrene-styrene copolymer. Xyoo 1970, Nafion membrane tau hloov cov roj teeb uas muaj sulfonated polystyrogen-divinylbenzene copolymer ua cov roj teeb txheem rau cov roj teeb uas pauv proton.
Lub membrane uas muaj roj sulfonic acid yuav tsum ua haujlwm tsawg dua 100 ° C, thiab thaum qhov kub siab dua 100 ° C, lub membrane yuav qhuav sai sai thiab cov ionic domains hauv cov qauv membrane yuav tawg, ua rau muaj kev txo qis ntawm cov conductivity. Tam sim no, feem ntau cov roj cell ua haujlwm ntawm qhov kub qis dua 100 ° C, tab sis qhov no tsis zoo tshaj plaws. Yog li ntawd,cov txheej txheem pauv protonuas tuaj yeem hloov kho rau qhov kub siab yuav tsum tau txhim kho ntxiv. Qhov ntsuas ntau lawm muaj qhov cuam tshuam loj rau tus nqi tsim khoom ntawm daim nyias nyias pauv proton. Tus nqi ntawm daim nyias nyias pauv proton feem ntau yog tsim los ntawm peb ntu: (1) tus nqi khoom siv ionomer; (2) Tus nqi khoom siv ntawm cov polytetroxene nthuav dav thiab (3) tus nqi tsim zaj duab xis. Tus nqi khoom siv thiab kev tsim ntoo ob leeg raug cuam tshuam los ntawm qhov ntsuas ntau lawm. Thaum qhov ntsuas ntau lawm nce ntxiv los ntawm 1000 teeb / xyoo mus rau 10000 teeb / xyoo, tus nqi tsim khoom ntawm kev pauv proton thiab kev pauv zaj duab xis tuaj yeem txo qis los ntawm 77% thiab tag nrho tus nqi tuaj yeem txo qis los ntawm 70%.
VET Technology Co., Ltd yog lub chaw haujlwm hluav taws xob ntawm VET Group, uas yog lub tuam txhab thev naus laus zis hauv tebchaws uas tshwj xeeb hauv kev tshawb fawb thiab kev txhim kho, kev tsim khoom, kev muag khoom thiab kev pabcuam ntawm cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob tshiab, feem ntau yog ua lag luam hauv cov koob tshuab, cov twj nqus tsev, roj teeb & roj teeb ntws, thiab lwm yam khoom siv tshiab.
Tau ntau xyoo los no, peb tau sib sau ua ke ib pawg neeg muaj kev paub txog thiab muaj peev xwm tshiab hauv kev lag luam thiab pab pawg R & D, thiab muaj kev paub dhau los hauv kev tsim khoom thiab kev siv engineering. Peb tau ua tiav cov kev tshawb pom tshiab hauv kev tsim khoom siv automation thiab kev tsim cov kab ntau lawm semi-automated, uas ua rau peb lub tuam txhab muaj kev sib tw zoo hauv tib lub lag luam.
Nrog rau kev tshawb fawb thiab kev txhim kho (R & D) muaj peev xwm los ntawm cov ntaub ntawv tseem ceeb mus rau cov khoom siv kawg, cov thev naus laus zis tseem ceeb thiab cov cuab yeej tseem ceeb ntawm cov cai tswjfwm kev txawj ntse ywj pheej tau ua tiav ntau yam kev tsim kho tshiab hauv kev tshawb fawb thiab thev naus laus zis. Vim yog cov khoom zoo ruaj khov, cov qauv tsim zoo tshaj plaws thiab kev pabcuam tom qab muag zoo, peb tau txais kev lees paub thiab kev ntseeg siab los ntawm peb cov neeg siv khoom.
Cov ntaub thaiv Nafion PFSA uas VET Energy tsim yog cov ntaub thaiv uas tsis muaj zog ua los ntawm Nafion PFSA polymers, perfluorinated sulfonic acid/polytetrafluoroethylene copolymers hauv daim ntawv acid (H+). Cov ntaub thaiv Nafion PFSA siv dav hauvdaim nyias nyias pauv proton(PEM) cov roj cell thiab cov dej electrolysers. Hauv ntau yam electrochemical cells, cov membranes ua haujlwm ua cov separators thiab cov electrolytes khov thiab yuav tsum tau xaiv cov cations hla cov cell junctions. Cov polymer no tiv taus tshuaj lom neeg thiab ruaj khov.
