In proton exchange membranefuel cell, iyo catalytic oxidation yemaproton ndeye cathode mukati me membrane, panguva imwe chete, iyo anode yemaerekitironi kuti iende kune cathode kuburikidza nekunze dunhu, iyo qualitative yakasanganiswa nemagetsi uye cathodic kuderedzwa kweokisijeni pamusoro pemvura inogadzirwa, simba rinogadzirwa nemagetsi kuburikidza nekunze kwedunhu conduction. Mune yakajairika proton exchange membrane fuel cell membrane electrode uye kushanda zvakanaka chinhu chakakosha, uye yakakwira proton conductivity chinhu chakakosha cheproton exchange membrane zvinhu. Proton exchange membrane inowanzoumbwa nekuparadzanisa chimiro che hydrophobic uye hydrophilic, hydrophobic chimiro kudzivirira kunyura kwemvura yakawandisa, kuita kuti kuputika kwemembrane kwakaderera, chengetedza mechanical kugadzikana kwe membrane; Hydrophilic mapoka e sulfate ari kuitisa chiteshi anopa zvakakwana, anogona kuva mapurotoni kubva anode kusvika cathode, gasi mafuta musanganiswa panguva imwe chete.
Early proton exchange membrane fuel cell ane zvipingamupinyi zvemutengo wakakwira uye hupenyu hupfupi nekuda kwekushandisa sulfonated polystyrene-styrene copolymer membranes. Mumakore ekuma1970, membrane yeNafion yakatsiva sulfonated polystyrogen-divinylbenzene copolymer membrane seyakajairwa membrane yeproton exchange membrane mafuta masero.
Iyo yese-gas sulfonic acid membrane inoda kushanda isingasviki 100 ° C, uye kana tembiricha yakakwira kupfuura 100 ° C, membrane inodonha nekukurumidza uye iyo ionic domains mu membrane chimiro inodonha, zvichikonzera kuderera kukuru kweiyo conductivity. Parizvino, masero emafuta akawanda anoshanda patembiricha iri pasi pe100 ° C, asi izvi hazvina kunaka. Naizvozvo,proton kuchinjana membranesiyo inogona kuenderana nekupisa kwakanyanya kunoda kuvandudzwa. Chiyero chekugadzira chine mhedzisiro yakakosha pamutengo wekugadzira weproton exchange membrane. Mutengo weproton exchange membrane inonyanya kuumbwa nezvikamu zvitatu: (1) ionomer material cost; (2) Mutengo wezvinhu zve polytetroxene yakawedzerwa uye (3) mutengo wekugadzira firimu. Mutengo wezvinhu uye huni hwekugadzira zvese zvinokanganiswa nechiyero chekugadzira. Kana chiyero chekugadzira chikawedzera kubva ku1000 seti / gore kusvika ku10000 seti / gore, mutengo wekugadzira wekuchinjana kweproton uye kuchinjanisa firimu unogona kudzikiswa ne77% uye mutengo wakakwana unogona kudzikiswa ne70%.
VET Technology Co., Ltd idhipatimendi resimba reVET Group, rinova bhizinesi repamusoro-soro renyika rinoshanda mukutsvagisa nekusimudzira, kugadzira, kutengesa uye sevhisi yemotokari uye zvikamu zvesimba idzva, kunyanya inobata mota dzakatevedzana, vacuum pombi, mafuta cell & kuyerera bhatiri, uye zvimwe zvitsva zvemberi zvinhu.
Kwemakore, takaunganidza boka rematarenda eindasitiri ane ruzivo uye ane hunyanzvi uye zvikwata zveR & D, uye tine ruzivo rwakapfuma runoshanda mukugadzira chigadzirwa uye engineering maapplication. Isu takaramba tichiwana mabhindauko matsva mukugadzira zvigadzirwa zvekushandisa otomatiki uye semi-otomatiki yekugadzira mutsara dhizaini, iyo inogonesa kambani yedu kuchengetedza kukwikwidza kwakasimba muindasitiri imwe chete.
Nekugona kweR & D kubva kuzvinhu zvakakosha kupedzisa zvigadzirwa zvekushandisa, musimboti uye hunyanzvi hwetekinoroji yekodzero dzakazvimirira dzepfuma yakawana huwandu hwehunyanzvi hwesainzi uye tekinoroji. Nekuda kwekugadzikana kwemhando yechigadzirwa, yakanakisa-inodhura-inoshanda dhizaini dhizaini uye yemhando yepamusoro mushure mekutengesa sevhisi, isu takunda kuzivikanwa uye kuvimba nevatengi vedu.
Nafion PFSA membranes inogadzirwa neVET Energy haina-kusimbisa membranes yakavakirwa paNafion PFSA polima, perfluorinated sulfonic acid/polytetrafluoroethylene copolymers muacid (H+) fomu. Nafion PFSA membranes inoshandiswa zvakanyanya mukatiproton exchange membrane(PEM) masero emafuta uye emagetsi emvura. Mumaseru akasiyana-siyana emagetsi emagetsi, mamembrane anoita seanoparadzanisa uye akasimba emagetsi uye anodiwa kuti asarudze kupfuudza cations kuburikidza nesero junctions. Iyo polymer inodzivirira kemikari uye inogara kwenguva refu.
