In proton pauv membraneroj cell, catalytic oxidation ntawm protons yog cathode nyob rau hauv daim nyias nyias, tib lub sij hawm, lub anode ntawm electrons txav mus rau cathode los ntawm ib tug sab nraud Circuit Court, qualitative ua ke nrog hluav taws xob thiab cathodic txo cov pa oxygen nyob rau saum npoo ntawm cov dej tsim, lub zog tsim los ntawm cov hluav taws xob los ntawm kev sib txuas sab nraud. Nyob rau hauv raug proton txauv membrane roj cell membrane electrode thiab efficiency yog ib qho tseem ceeb, thiab high proton conductivity yog ib qho tseem ceeb feature ntawm proton exchange membrane cov ntaub ntawv. Proton txauv membrane feem ntau yog tsim los ntawm cov qauv zoo sib cais ntawm hydrophobic thiab hydrophilic, hydrophobic qauv kom tsis txhob muaj cov dej nqus dej ntau dhau, ua rau cov o ntawm daim nyias nyias yog qis dua, tswj kev ruaj ntseg ntawm daim nyias nyias; Hydrophilic pawg ntawm sulfate yog ua channel muab txaus, tuaj yeem ua tau protons los ntawm anode mus rau cathode, roj sib tov tib lub sijhawm.
Thaum ntxov proton pauv membrane roj hlwb muaj qhov tsis zoo ntawm tus nqi siab thiab lub neej luv vim yog siv sulfonated polystyrene-styrene copolymer membranes. Nyob rau xyoo 1970, Nafion membrane hloov cov sulfonated polystyrogen-divinylbenzene copolymer membrane raws li tus qauv membrane rau proton pauv membrane roj hlwb.
Tag nrho cov roj sulfonic acid daim nyias nyias yuav tsum tau ua haujlwm tsawg dua 100 ° C, thiab thaum kub siab tshaj 100 ° C, daim nyias nyias dehydrates sai thiab cov ionic domains nyob rau hauv daim nyias nyias nyias, uas ua rau ib tug tseem ceeb txo nyob rau hauv conductivity. . Tam sim no, feem ntau cov roj hlwb ua haujlwm ntawm qhov kub qis dua 100 ° C, tab sis qhov no tsis zoo. Yog li ntawd,proton pauv membranesuas tuaj yeem hloov mus rau qhov kub thiab txias yuav tsum tau tsim ntxiv. Cov nplais ntau lawm muaj qhov cuam tshuam tseem ceeb rau kev tsim cov nqi ntawm cov khoom sib pauv proton. Tus nqi ntawm proton pauv daim nyias nyias yog tsim los ntawm peb qhov chaw: (1) ionomer khoom nqi; (2) Cov nqi ntawm cov khoom siv nthuav dav polytetroxene thiab (3) cov nqi tsim cov yeeb yaj kiab. Tus nqi ntawm cov khoom siv thiab kev tsim cov ntoo yog ob qho tib si cuam tshuam los ntawm kev tsim khoom. Thaum qhov ntsuas ntau lawm nce los ntawm 1000 teeb / xyoo mus rau 10000 teeb / xyoo, cov nqi tsim khoom ntawm cov khoom siv hluav taws xob thiab cov yeeb yaj kiab tuaj yeem raug txo los ntawm 77% thiab tag nrho cov nqi tuaj yeem txo los ntawm 70%.
VET Technology Co., Ltd yog lub tuam txhab hluav taws xob ntawm VET Group, uas yog lub teb chaws high-tech enterprise tshwj xeeb hauv kev tshawb fawb thiab kev tsim kho, tsim khoom, muag thiab kev pabcuam ntawm tsheb thiab lub zog tshiab, feem ntau yog kev lag luam hauv lub cev muaj zog, lub tshuab nqus tsev twj, roj cell & ntws roj teeb, thiab lwm yam khoom siv tshiab.
Ntau xyoo dhau los, peb tau sib sau ua ke ib pab pawg neeg paub txog kev lag luam thiab cov txuj ci tshiab thiab R & D pab pawg, thiab muaj kev paub zoo hauv cov khoom tsim thiab kev siv engineering. Peb tau ua tiav tsis tu ncua kev ua tiav tshiab hauv cov khoom tsim cov txheej txheem cov khoom siv automation thiab semi-automated ntau lawm kab tsim, uas ua rau peb lub tuam txhab muaj kev sib tw muaj zog hauv kev lag luam tib yam.
Nrog R & D muaj peev xwm los ntawm cov ntaub ntawv tseem ceeb mus rau qhov kawg cov khoom siv, cov thev naus laus zis thiab cov thev naus laus zis tseem ceeb ntawm kev ywj pheej cov cuab yeej cuab tam tau ua tiav ntau qhov kev tshawb fawb thiab thev naus laus zis tshiab. Los ntawm kev tsim txiaj ntawm cov khoom lag luam ruaj khov, qhov zoo tshaj plaws tus nqi tsim qauv thiab cov kev pabcuam zoo tom qab muag, peb tau txais kev lees paub thiab kev ntseeg siab los ntawm peb cov neeg siv khoom.
Nafion PFSA daim nyias nyias tsim los ntawm VET Zog yog cov khoom siv tsis muaj zog raws li Nafion PFSA polymers, perfluorinated sulfonic acid / polytetrafluoroethylene copolymer hauv acid (H +). Nafion PFSA daim nyias nyias yog siv dav hauvproton pauv membrane(PEM) roj hlwb thiab dej electrolysers. Nyob rau hauv ntau yam ntawm electrochemical hlwb, daim nyias nyias ua raws li cov khoom sib cais thiab cov khoom electrolytes thiab yuav tsum tau xaiv cov cations los ntawm cov cell junctions. Lub polymer yog chemically resistant thiab ruaj.
