In membrane yekuchinjana kweprotoniSero remafuta, catalytic oxidation yemapurotoni iri cathode mukati me membrane, panguva imwe chete, anode yemaerekitironi kuti afambe achienda ku cathode kuburikidza nedunhu rekunze, qualitative pamwe chete ne electronic uye cathodic reduction ye okisijeni pamusoro pemvura inogadzirwa, simba rinogadzirwa nemagetsi kuburikidza ne external circuit conduction. Mu typical proton exchange membrane fuel cell membrane electrode uye kushanda zvakanaka chinhu chakakosha, uye high proton conductivity chinhu chakakosha chezvinhu zve proton exchange membrane. Proton exchange membrane inowanzo umbwa ne hydrophobic uye hydrophilic, hydrophobic structure yakanaka kudzivirira mvura yakawanda kunyura, kuita kuti membrane iite shoma, kuchengetedza kugadzikana kwe membrane; Hydrophilic groups of sulfate iri kuita channel inopa zvakakwana, inogona kuva mapurotoni kubva kune anode kuenda kune cathode, gasi fuel musanganiswa panguva imwe chete.
Masero emafuta ekuchinjana kwemapurotoni ekutanga ane dambudziko rekuti anodhura zvakanyanya uye anogara kwenguva pfupi nekuda kwekushandiswa kwemamembrane e polystyrene-styrene copolymer ane sulfonated. Muma1970, Nafion membrane yakatsiva sulfonated polystyrogen-divinylbenzene copolymer membrane senzira yakajairika yemasero emafuta ekuchinjana kwemapurotoni.
Kamudzira kese kegasi resulfonic acid kanofanira kushanda patembiricha iri pasi pe100°C, uye kana tembiricha yakakwira kupfuura 100°C, kamudzira kanopera mvura nekukurumidza uye nzvimbo dzeionic dziri muchimiro chekamudzira dzinodonha, zvichikonzera kudzikira kukuru kwe conductivity. Parizvino, ma fuel cell mazhinji anoshanda patembiricha iri pasi pe100°C, asi izvi hazvina kunaka. Nokudaro,mapurotoni ekutsinhana kwemariZvinogona kuchinjika nekupisa kwakanyanya zvinoda kuvandudzwa. Chikero chekugadzira chine mhedzisiro yakakura pamutengo wekugadzira weproton exchange membrane. Mutengo weproton exchange membrane unonyanya kuumbwa nezvikamu zvitatu: (1) mutengo wezvinhu zve ionomer; (2) Mutengo wezvinhu zve polytetroxene yakawedzerwa uye (3) mutengo wekugadzira mafirimu. Mutengo wezvinhu uye huni hwekugadzira zvese zvinokanganiswa nechikero chekugadzira. Kana chiyero chekugadzira chikawedzera kubva pa1000 seti pagore kusvika pa10000 seti pagore, mutengo wekugadzira weproton exchange nefirimu exchange unogona kuderedzwa ne77% uye mutengo wese unogona kuderedzwa ne70%.
VET Technology Co., Ltd ibazi rezvemagetsi reVET Group, iro riri kambani yenyika yepamusoro-soro inonyanya kushandira mukutsvaga nekugadzira, kugadzira, kutengesa uye sevhisi yezvikamu zvemagetsi zvemotokari nezvitsva, kunyanya ichitengesa mota dzakatevedzana, mapombi evacuum, mabhatiri emafuta nemagetsi, nezvimwe zvinhu zvitsva zvepamusoro.
Mumakore apfuura, takaunganidza boka revanhu vane ruzivo uye vane hunyanzvi muindasitiri pamwe nemapoka eR & D, uye tine ruzivo rwakakura mukugadzira zvigadzirwa uye mashandisirwo emainjiniya. Takaramba tichiwana budiriro itsva mukugadzira zvigadzirwa otomatiki uye dhizaini yemitsetse yekugadzira yakagadzirwa otomatiki, izvo zvinoita kuti kambani yedu irambe iine makwikwi akasimba muindasitiri imwe chete.
Nekugona kweR & D kubva pazvinhu zvakakosha kusvika kuzvigadzirwa zvekupedzisira, matekinoroji makuru uye akakosha ekodzero dzepfuma yepfungwa dzakazvimiririra awana hunyanzvi hwakawanda hwesainzi netekinoroji. Nekuda kwemhando yepamusoro yechigadzirwa, dhizaini yepamusoro-soro uye sevhisi yepamusoro-soro mushure mekutengesa, tawana kuzivikanwa nekuvimba nevatengi vedu.
Ma membrane eNafion PFSA anogadzirwa neVET Energy ma membrane asina kusimbiswa akavakirwa paNafion PFSA polymers, ma copolymers esulfonic acid/polytetrafluoroethylene ane perfluorinated muchimiro che acid (H+). Ma membrane eNafion PFSA anoshandiswa zvakanyanya mumembrane yekuchinjana kweprotoniMasero emafuta (PEM) nemaelectrolyser emvura. Mumasero akasiyana-siyana emagetsi, mamembrane anoshanda sevanoparadzanisa uye maelectrolytes akasimba uye anodiwa kuti apfuure macations nepakati pemajunction emasero. Iyo polymer inodzivirira makemikari uye inogara kwenguva refu.
