In lera la phapanyetsano ea protonmafura cell, catalytic oxidation ea protons ke cathode ka hare ho lera, ka nako e tšoanang, anode ea dieleketerone ho fallela cathode ka potoloho ea ka ntle, boleng ho kopantswe le phokotso ea elektroniki le cathodic ea oksijene holim'a metsi a hlahisoang, matla a hlahisoang ke motlakase ka ho tsamaisa potoloho e kantle. Ka tloaelo proton exchange membrane fuel cell membrane electrode le ts'ebetso e ntle ke ntlha ea bohlokoa, 'me proton conductivity e phahameng ke tšobotsi ea bohlokoa ea thepa ea proton exchange membrane. Proton exchange membrane hangata e entsoe ka sebopeho se setle sa karohano ea hydrophobic le hydrophilic, sebopeho sa hydrophobic ho qoba ho ts'oaroa ha metsi ho feteletseng, ho etsa hore ho ruruha ha lera ho fokotsehe, ho boloka botsitso ba mochini oa lera; Lihlopha tsa Hydrophilic tsa sulfate li tsamaisa mocha o fana ka ho lekaneng, e ka ba protons ho tloha ho anode ho ea ho cathode, motsoako oa mafura a khase ka nako e le 'ngoe.
Lisele tsa peterole tsa pele tsa phapanyetsano ea proton li na le bofokoli ba litšenyehelo tse phahameng le bophelo bo bokhuts'oane ka lebaka la ts'ebeliso ea li-membrane tsa sulfonated polystyrene-styrene copolymer. Lilemong tsa bo-1970, lera la Nafion le ile la nkela lera la sulfonated polystyrogen-divinylbenzene copolymer e le lesela le tloaelehileng bakeng sa lisele tsa peterole tsa phapanyetsano ea proton.
The all-gas sulfonic acid membrane e hloka ho sebetsa ka tlase ho 100 ° C, 'me ha mocheso o phahame ho feta 100 ° C, lera le felloa ke metsi ka potlako' me libaka tsa ionic tsa sebopeho sa membrane lia oa, e leng se bakang phokotso e kholo ea conductivity. . Hajoale, lisele tse ngata tsa mafura li sebetsa ka mocheso o ka tlase ho 100 ° C, empa sena ha se hantle. Ka hona,li-membrane tsa phapanyetsano ea protontse ka ikamahanyang le mocheso o phahameng li hloka ho ntlafatsoa ho ea pele. Sekala sa tlhahiso se na le phello e kholo litšenyehelong tsa tlhahiso ea membrane ea phapanyetsano ea proton. Litsenyehelo tsa lera la phapanyetsano ea proton haholo-holo li entsoe ka likarolo tse tharo: (1) litšenyehelo tsa thepa ea ionomer; (2) Theko ea thepa ea polytetroxene e atolositsoeng le (3) litšenyehelo tsa tlhahiso ea lifilimi. Litšenyehelo tsa thepa le lehong la tlhahiso li angoa ke tekanyo ea tlhahiso. Ha tekanyo ea tlhahiso e eketseha ho tloha ho 1000 sets / selemo ho ea ho 10000 sets / selemo, litšenyehelo tsa tlhahiso ea phapanyetsano ea proton le phapanyetsano ea lifilimi li ka fokotsoa ka 77% 'me litšenyehelo tsohle li ka fokotsoa ka 70%.
