Mfundo yaikulu ya membrane yosinthana ya proton, msika ndi kuyambitsidwa kwa proton yathu yopanga zinthu za membrane yosinthana

In nembanemba yosinthira mapulotoniMafuta a Cell, ma protein oxidation oyambitsa ma protein ndi cathode mkati mwa nembanemba, nthawi yomweyo, anode ya ma elekitironi kuti asunthire ku cathode kudzera mu dera lakunja, qualitative pamodzi ndi electronic ndi cathodic kuchepetsa mpweya pamwamba pa madzi opangidwa, mphamvu yopangidwa ndi magetsi kudzera mu dera lakunja. Mu nembanemba ya proton exchange membrane, mafuta a cell membrane electrode ndi magwiridwe antchito ndizofunikira kwambiri, ndipo ma protein conductivity apamwamba ndi gawo lofunikira la zinthu za nembanemba ya proton exchange. Nembanemba ya Proton exchange nthawi zambiri imapangidwa ndi kapangidwe kabwino ka hydrophobic ndi hydrophilic, hydrophobic kapangidwe kuti apewe kuyamwa kwa madzi ambiri, zimapangitsa kutupa kwa nembanemba kukhala kochepa, kusunga bata la nembanemba; Magulu a hydrophilic a sulfate akupereka njira yokwanira, ma protoni amatha kukhala kuchokera ku anode kupita ku cathode, kusakaniza kwa mafuta a gasi nthawi imodzi.

Maselo oyambira amafuta a membrane ya proton exchange ali ndi zovuta za mtengo wokwera komanso moyo waufupi chifukwa chogwiritsa ntchito ma membrane a sulfonated polystyrene-styrene copolymer. M'zaka za m'ma 1970, membrane ya Nafion idalowa m'malo mwa membrane ya sulfonated polystyrogen-divinylbenzene copolymer ngati membrane yokhazikika ya maselo amafuta a membrane ya proton exchange.

Nembanemba ya sulfonic acid yokhala ndi mpweya wonse iyenera kugwira ntchito pa kutentha kosakwana 100 ° C, ndipo kutentha kukapitirira 100 ° C, nembanembayo imauma mofulumira ndipo ma ionic domains mu kapangidwe ka nembanemba amagwa, zomwe zimapangitsa kuti conductivity ichepe kwambiri. Pakadali pano, ma fuel cell ambiri amagwira ntchito pa kutentha kosakwana 100 ° C, koma izi sizoyenera. Chifukwa chake,ma membrane osinthira ma protonzomwe zingathe kusintha kutentha kwambiri ziyenera kukulitsidwanso. Mulingo wopanga umakhudza kwambiri mtengo wopanga wa nembanemba yosinthira ma proton. Mtengo wa nembanemba yosinthira ma proton umapangidwa makamaka ndi magawo atatu: (1) mtengo wa zinthu za ionomer; (2) Mtengo wa zinthu za polytetroxene yowonjezereka ndi (3) mtengo wopanga mafilimu. Mtengo wa zinthu ndi matabwa opangira zonse zimakhudzidwa ndi mulingo wopanga. Pamene mulingo wopanga ukukwera kuchoka pa 1000 seti pachaka kufika pa 10000 seti pachaka, mtengo wopanga wa kusintha ma proton ndi kusintha mafilimu ukhoza kuchepetsedwa ndi 77% ndipo mtengo wonse ukhoza kuchepetsedwa ndi 70%.

VET Technology Co., Ltd ndi dipatimenti ya mphamvu ya VET Group, yomwe ndi kampani yapamwamba yapadziko lonse yomwe imayang'anira kafukufuku ndi chitukuko, kupanga, kugulitsa ndi kutumikira magalimoto ndi zida zatsopano zamagetsi, makamaka yogulitsa magalimoto angapo, mapampu a vacuum, batire yamafuta ndi ma flow, ndi zinthu zina zatsopano zamakono.

Kwa zaka zambiri, tasonkhanitsa gulu la akatswiri odziwa bwino ntchito komanso opanga zinthu zatsopano komanso magulu a R & D, ndipo tili ndi luso lochuluka pakupanga zinthu ndi kugwiritsa ntchito uinjiniya. Takhala tikupeza zatsopano pakupanga zida zopangira zinthu zokha komanso kupanga mizere yopanga zinthu zokha, zomwe zimathandiza kampani yathu kukhalabe ndi mpikisano wamphamvu mumakampani omwewo.

Ndi luso la R & D kuyambira pa zipangizo zofunika mpaka zinthu zogwiritsidwa ntchito, ukadaulo wofunikira komanso wofunikira wa ufulu wodziyimira pawokha wapeza zatsopano zambiri zasayansi ndi ukadaulo. Chifukwa cha khalidwe lokhazikika la malonda, kapangidwe kabwino kwambiri kotsika mtengo komanso ntchito yabwino kwambiri yogulitsa pambuyo pogulitsa, tapeza kudziwika ndi kudalirika kuchokera kwa makasitomala athu.

Ma membrane a Nafion PFSA opangidwa ndi VET Energy ndi ma membrane osalimbikitsidwa pogwiritsa ntchito ma polymer a Nafion PFSA, ma copolymer a sulfonic acid/polytetrafluoroethylene omwe ali ndi perfluorinated mu mawonekedwe a acid (H+). Ma membrane a Nafion PFSA amagwiritsidwa ntchito kwambiri munembanemba yosinthira mapulotoniMaselo amafuta (PEM) ndi ma elekitiroma amadzi. Mu maselo osiyanasiyana amagetsi, ma nembanemba amagwira ntchito ngati olekanitsa ndi ma elekitiroma olimba ndipo amafunika kudutsa ma cations mwachisawawa kudzera m'malo olumikizirana maselo. Polimayo ndi yolimba komanso yolimba.
