Proton exchange membrane mfundo, msika ndi kupanga ma protoni athu oyambitsa kaphatikizidwe ka membrane

In Kusinthanitsa kwa proton membranemafuta selo, chothandizira makutidwe ndi okosijeni wa mapulotoni ndi cathode mkati nembanemba, pa nthawi yomweyo, anode ma elekitironi kusamukira ku cathode kudzera dera kunja, Mkhalidwe pamodzi ndi magetsi ndi cathodic kuchepetsa mpweya padziko madzi opangidwa, mphamvu yopangidwa ndi magetsi kudzera mumayendedwe ozungulira akunja. Nthawi zambiri pulotoni kusinthanitsa nembanemba mafuta cell membrane elekitirodi ndi dzuwa ndi chinthu chofunika kwambiri, ndi mkulu pulotoni madutsidwe ndi mbali yofunika ya proton kuwombola nembanemba zipangizo. Protoni kuwombola nembanemba zambiri wapangidwa wabwino kulekana dongosolo la hydrophobic ndi hydrophilic, dongosolo hydrophobic kupewa kwambiri mayamwidwe madzi, kupanga kutupa nembanemba ndi m`munsi, kukhalabe mawotchi bata nembanemba; Magulu a Hydrophilic a sulphate akuyendetsa njira yokwanira, akhoza kukhala ma protoni kuchokera ku anode kupita ku cathode, kusakaniza kwamafuta amafuta nthawi yomweyo.

Maselo oyambilira a proton exchange nembanemba mafuta amakhala ndi zovuta zotsika mtengo komanso moyo waufupi chifukwa chogwiritsa ntchito nembanemba za sulfonated polystyrene-styrene copolymer. M'zaka za m'ma 1970, nembanemba ya Nafion inalowa m'malo mwa nembanemba ya sulfonated polystyrogen-divinylbenzene copolymer ngati nembanemba yosinthira ma cell amafuta a proton.

Onse gasi sulfonic acid nembanemba ayenera kugwira ntchito pa zosakwana 100 ° C, ndipo pamene kutentha ndi apamwamba kuposa 100 ° C, nembanemba dehydrates mofulumira ndi madera ionic mu nembanemba dongosolo kugwa, chifukwa cha kuchepa kwambiri conductivity. . Pakali pano, maselo ambiri amafuta amagwira ntchito pa kutentha kosachepera 100 ° C, koma izi sizoyenera. Chifukwa chake,kusintha kwa proton membraneszomwe zingagwirizane ndi kutentha kwakukulu ziyenera kupititsa patsogolo. Kukula kwapang'onopang'ono kumakhudza kwambiri mtengo wopanga ma proton exchange membrane. Mtengo wa nembanemba yosinthira pulotoni umapangidwa makamaka ndi magawo atatu: (1) mtengo wazinthu za ionomer; (2) Mtengo wazinthu zowonjezera polytetroxene ndi (3) mtengo wopanga mafilimu. Mtengo wazinthu ndi matabwa opangira zonse zimakhudzidwa ndi kuchuluka kwa kupanga. Pamene sikelo yopangira ikukwera kuchokera ku seti 1000/chaka kufika ku seti 10000/chaka, mtengo wopangira ma proton kusinthana ndi kusinthana kwa mafilimu ukhoza kuchepetsedwa ndi 77% ndipo mtengo wonsewo ukhoza kuchepetsedwa ndi 70%.

VET Technology Co., Ltd ndi dipatimenti yamphamvu ya VET Group, yomwe ndi bizinesi yapamwamba kwambiri padziko lonse lapansi yomwe imagwira ntchito pa kafukufuku ndi chitukuko, kupanga, malonda ndi ntchito zamagalimoto ndi mphamvu zatsopano, makamaka zomwe zimagwira pamagalimoto angapo, mapampu a vacuum, mafuta cell & flow batire, ndi zina zatsopano zapamwamba.

Kwa zaka zambiri, tasonkhanitsa gulu la akatswiri odziwa bwino ntchito komanso akatswiri amakampani ndi magulu a R & D, ndipo takhala ndi zokumana nazo zambiri pakupanga zinthu ndi kugwiritsa ntchito uinjiniya. Takhala takwaniritsa zopambana zatsopano pakupanga zida zopangira zinthu zokha komanso kapangidwe ka makina opangira makina, zomwe zimathandiza kampani yathu kukhalabe yampikisano wamphamvu pamakampani omwewo.

Ndi luso la R & D kuchokera ku zida zazikulu mpaka kumaliza ntchito, matekinoloje ofunikira komanso ofunikira paufulu wodziyimira pawokha wazinthu zaluso akwaniritsa zatsopano zingapo zasayansi ndiukadaulo. Chifukwa cha khalidwe lokhazikika lazinthu, ndondomeko yabwino kwambiri yotsika mtengo komanso ntchito yapamwamba pambuyo pogulitsa malonda, tapambana kuzindikira ndi kudalira makasitomala athu.

Ma membrane a Nafion PFSA opangidwa ndi VET Energy ndi nembanemba osalimbitsa kutengera ma polima a Nafion PFSA, perfluorinated sulfonic acid/polytetrafluoroethylene copolymers mu acid (H+) mawonekedwe. Ma membrane a Nafion PFSA amagwiritsidwa ntchito kwambiri muKusinthanitsa kwa proton membrane(PEM) ma cell amafuta ndi ma electrolyser amadzi. M'maselo osiyanasiyana a electrochemical, ma nembanemba amakhala ngati olekanitsa ndi ma electrolyte olimba ndipo amafunikira kuti adutse ma cation kudzera pamagulu a cell. Polima ndi yolimbana ndi mankhwala komanso yolimba.
