Umgaqo we-Proton exchange membrane, imakethi kunye nemveliso yethu ye-proton ye-exchange membrane ukwazisa ngemveliso

In i-membrane yokutshintshiselana kweprotonI-fuel cell, i-catalytic oxidation yeeproton yi-cathode ngaphakathi kwi-membrane, kwangaxeshanye, i-anode yee-electron ukuya kwi-cathode ngesekethe yangaphandle, umgangatho wayo udibene nokunciphisa i-oksijini ye-elektroniki kunye ne-cathodic kumphezulu wamanzi avelisiweyo, amandla aveliswa ngumbane ngokusebenzisa i-external circuit conduction. Kwi-proton exchange membrane eqhelekileyo, i-fuel cell membrane electrode kunye nokusebenza kakuhle yinto ephambili, kwaye i-proton conductivity ephezulu luphawu olubalulekileyo lwezinto ze-proton exchange membrane. I-Proton exchange membrane idla ngokwakhiwa ngesakhiwo esihle sokwahlulwa kwe-hydrophobic kunye ne-hydrophilic, isakhiwo se-hydrophobic ukuze kuthintelwe ukufunxwa kwamanzi okugqithisileyo, ukwenza ukudumba kwe-membrane kuphantsi, ukugcina uzinzo loomatshini lwe-membrane; Amaqela e-hydrophilic e-sulfate aqhuba itshaneli anika ngokwaneleyo, iiprotons zinokuba ukusuka kwi-anode ukuya kwi-cathode, umxube we-gas fuel ngaxeshanye.

Iiseli zamafutha ze-proton exchange membrane zakuqala zineengxaki zokuba nexabiso eliphezulu kunye nobomi obufutshane ngenxa yokusetyenziswa kwee-membrane ze-polystyrene-styrene copolymer ezifakwe i-sulfonated. Kwiminyaka yoo-1970, i-Nafion membrane yathatha indawo ye-polystyrogen-divinylbenzene copolymer membrane njenge-membrane eqhelekileyo yeeseli zamafutha ze-proton exchange membrane.

I-membrane ye-sulfonic acid enegesi yonke kufuneka isebenze ngaphantsi kwe-100 ° C, kwaye xa ubushushu buphezulu kune-100 ° C, i-membrane iyaphela ngokukhawuleza kwaye iindawo ze-ionic kwisakhiwo se-membrane ziyawa, nto leyo ebangela ukwehla okukhulu kokuqhuba. Okwangoku, uninzi lwee-fuel cells zisebenza kumaqondo obushushu angaphantsi kwe-100 ° C, kodwa oku akulunganga. Ke ngoko,ii-membrane zokutshintshiselana kweeprotonEzinokumelana namaqondo obushushu aphezulu kufuneka ziphuculwe ngakumbi. Isikali semveliso sinefuthe elikhulu kwindleko yokwenziwa kwe-proton exchange membrane. Ixabiso le-proton exchange membrane lenziwe ikakhulu ngamacandelo amathathu: (1) iindleko zezinto ze-ionomer; (2) Iindleko zezinto ze-polytetroxene eyandisiweyo kunye (3) iindleko zokwenziwa kwefilimu. Iindleko zezinto kunye nomthi wokwenziwa zombini zichaphazeleka sisikali semveliso. Xa isikali semveliso sinyuka ukusuka kwi-1000 sets/ngonyaka ukuya kwi-10000 sets/ngonyaka, iindleko zokwenziwa kwe-proton exchange kunye ne-film exchange zinokuncitshiswa nge-77% kwaye iindleko zizonke zinokuncitshiswa nge-70%.

I-VET Technology Co., Ltd lisebe lamandla le-VET Group, elishishini lesizwe elinobuchwepheshe obuphezulu eligxile kuphando nophuhliso, imveliso, ukuthengisa kunye nenkonzo yezixhobo zamandla eemoto kunye nezitsha, ikakhulu lisebenza ngochungechunge lweemoto, iipompo ze-vacuum, ibhetri ye-fuel cell & flow, kunye nezinye izinto ezintsha eziphambili.

Kwiminyaka edlulileyo, siye saqokelela iqela leetalente zoshishino ezinamava nezintsha kunye namaqela e-R & D, kwaye sinamava amaninzi asebenzayo kuyilo lwemveliso kunye nezicelo zobunjineli. Siye safumana impumelelo entsha ngokuqhubekayo kwi-automation yezixhobo zenkqubo yokwenziwa kwemveliso kunye noyilo lwemigca yemveliso ezenzekelayo, evumela inkampani yethu ukuba igcine ukhuphiswano oluqinileyo kushishino olufanayo.

Ngenxa yezakhono zophando nophuhliso oluvela kwizixhobo eziphambili ukuya kwiimveliso zokugqibela zokusetyenziswa, ubuchwepheshe obuphambili kunye nobuphambili bamalungelo obunini bobuchwephesha obuzimeleyo bufezekise inani lezinto ezintsha zesayensi kunye netekhnoloji. Ngenxa yomgangatho wemveliso ozinzileyo, isikimu soyilo esingabizi kakhulu kunye nenkonzo esemgangathweni emva kokuthengisa, siphumelele ukuqatshelwa nokuthenjwa ngabathengi bethu.

Iimembrane zeNafion PFSA ezenziwe yiVET Energy ziimembrane ezingaqiniswanga ngokusekelwe kwiipolymers zeNafion PFSA, ii-copolymers ze-sulfonic acid/polytetrafluoroethylene ezifakwe i-perfluorinated kwimo ye-asidi (H+). Iimembrane zeNafion PFSA zisetyenziswa kakhulu kwii-membrane yokutshintshiselana kweprotonIiseli zamafutha (PEM) kunye nee-electrolysers zamanzi. Kwiintlobo ngeentlobo zeeseli ze-electrochemical, ii-membrane zisebenza njengabahluli kunye nee-electrolytes eziqinileyo kwaye kufuneka zidlule ii-cations ngokukhetha kwiindawo zokudibanisa iiseli. I-polymer ayixhathisi ngamakhemikhali kwaye ihlala ixesha elide.
