In kiriuhi whakawhiti pūmuaI roto i te pūtau wahie, ka puta te waikura catalytic o ngā porotini i roto i te katote i roto i te membrane, i te wa ano, ka neke te anode o ngā irahiko ki te katote mā te ara iahiko o waho, ka honoa te kounga ki te whakaiti hiko me te cathodic o te hāora i runga i te mata o te wai i hangaia, ka whakaputahia te hiko mā te ara iahiko o waho. I roto i te membrane whakawhiti porotini noa, ko te whai huatanga o te irahiko he mea nui, ā, ko te kawe porotini teitei he āhuatanga nui o ngā rauemi membrane whakawhiti porotini. Ko te membrane whakawhiti porotini he mea hanga ki te hanganga wehewehe pai o te hydrophobic me te hydrophilic, ka ārai i te mimiti wai nui o te hanganga hydrophobic, ka whakaiti i te pupuhi o te membrane, ka pupuri i te pumau miihini o te membrane; Ko ngā rōpū hydrophilic o te whanariki he hongere kawe e whakarato ana i te nui, ka taea te whakawhiti i ngā porotini mai i te anode ki te katote, te ranunga wahie hau i te wa ano.
Ko ngā ngoikoretanga o ngā pūtau wahie kiriuhi whakawhiti proton o mua ko te utu nui me te poto o te ora nā te whakamahinga o ngā kiriuhi polystyrene-styrene copolymer kua whakapūkarahia. I ngā tau 1970, i whakakapia te kiriuhi polystyrogen-divinylbenzene copolymer kua whakapūkarahia e te kiriuhi Nafion hei kiriuhi paerewa mō ngā pūtau wahie kiriuhi whakawhiti proton.
Me mahi te kiriuhi waikawa sulfonic hau-katoa i raro i te 100 °C, ā, ina teitei ake te pāmahana i te 100 °C, ka tere te maroke o te kiriuhi, ā, ka hinga ngā rohe ionic i roto i te hanganga kiriuhi, ka hua ake he hekenga nui o te kawe hiko. I tēnei wā, ko te nuinga o ngā pūtau wahie e mahi ana i ngā pāmahana i raro i te 100 °C, engari kāore tēnei i te tino pai. Nō reira,ngā kiriuhi whakawhiti pūmuaMe whakawhanake tonu i ngā mea ka taea te urutau ki ngā pāmahana teitei. He pānga nui tō te tauine whakaputa ki te utu hanga o te kiriuhi whakawhiti proton. Ko te utu o te kiriuhi whakawhiti proton e toru ngā wāhanga matua: (1) te utu rauemi ionomer; (2) te utu rauemi o te polytetroxene whānui me te (3) te utu hanga kiriata. Ka pāngia te utu rauemi me te hanga rakau e te tauine whakaputa. Ina piki te tauine whakaputa mai i te 1000 huinga/tau ki te 10000 huinga/tau, ka taea te whakaiti i te utu hanga o te whakawhiti proton me te whakawhiti kiriata mā te 77%, ā, ka taea te whakaiti i te utu katoa mā te 70%.
Ko VET Technology Co., Ltd te tari pūngao o VET Group, he umanga hangarau-tiketike ā-motu e tohunga ana ki te rangahau me te whanaketanga, te whakaputa, te hoko me te ratonga o ngā wāhanga motuka me ngā wāhanga pūngao hou, ko te nuinga e mahi ana i ngā raupapa motuka, ngā papu korehau, te pūtau wahie me te pākahiko rere, me ētahi atu rauemi matatau hou.
I roto i ngā tau, kua huihuia e mātou he rōpū o ngā pūkenga ahumahi auaha me ngā tīma R&D, ā, he nui hoki ō mātou wheako mahi i roto i te hoahoa hua me ngā tono hangarau. Kua tutuki tonu i a mātou ngā putanga hou i roto i te aunoatanga o ngā taputapu tukanga hanga hua me te hoahoa raina whakaputa haurua-aunoa, e āhei ai tā mātou kamupene ki te pupuri i te kaha whakataetae i roto i te ahumahi kotahi.
Mā ngā pūkenga R&D mai i ngā rauemi matua ki ngā hua tono whakamutunga, kua tutuki i ngā hangarau matua me ngā hangarau matua o ngā mana pupuri taonga hinengaro motuhake he maha ngā auahatanga pūtaiao me te hangarau. Nā te kounga hua pumau, te kaupapa hoahoa pai rawa atu me te utu whai hua me te ratonga muri-hoko kounga teitei, kua riro i a mātou te mana me te whakawhirinaki mai i ō mātou kiritaki.
Ko ngā kiriuhi Nafion PFSA i hangaia e VET Energy he kiriuhi kore-whakapakari i ahu mai i ngā pūmua Nafion PFSA, ngā copolymers waikawa sulfonic perfluorinated/polytetrafluoroethylene i te āhua waikawa (H+). He whānuitia te whakamahinga o ngā kiriuhi Nafion PFSA i roto ikiriuhi whakawhiti pūmua(PEM) ngā pūtau wahie me ngā kaiwhakamātautau wai. I roto i te whānuitanga o ngā pūtau hikohiko, ka mahi ngā kiriuhi hei wehewehe me ngā irahiko totoka, ā, me whiriwhiri kia tukuna ngā kationa mā roto i ngā hononga pūtau. He ātete matū te polymer, ā, he pakari hoki.
