E whakapau kaha ana a vet-china ki te whakarato rauemi pūtau wahie whai hua, inā koa ko te huihuinga hiko membrane pūtau wahie (MEA) mō te membrane whakawhiti proton (PEM). Kua hangaia tēnei huihuinga mā te whakamahi i ngā hangarau auaha hei whakarite i te mahi pai o ngā pūnaha pūtau wahie i roto i ngā momo horopaki tono, mai i te mana waka ki ngā pūnaha hiko kawe.
Ngā Whakatakotoranga o te huihuinga hiko kiriuhi:
| Matotoru | 50 µm. |
| Ngā Rahi | Ngā horahanga mata hohe 5 cm2, 16 cm2, 25 cm2, 50 cm2, 100 cm2 rānei. |
| Te Utaina o te Whakakōkī | Anode = 0.5 mg Pt/cm2. Cathode = 0.5 mg Pt/cm2. |
| Ngā momo huihuinga hiko membrane | Paparanga-3, paparanga-5, paparanga-7 (nō reira, i mua i te tono, whakamāramahia mai te maha o ngā paparanga MEA e pai ana ki a koe, me te whakarato hoki i te tuhi MEA). |
Ko te hanganga matua opūtau wahie MEA:
a) Kiriuhi Whakawhiti Pūmua (PEM): he kiriuhi pūmua motuhake kei waenganui.
b) Ngā Paparanga Whakakōkī: kei ngā taha e rua o te kiriuhi, he mea hanga i ngā whakakōkī konganuku utu nui.
c) Ngā Paparanga Horoho Hau (GDL): kei ngā taha o waho o ngā paparanga whakakorikori, he mea hanga i ngā rauemi muka.
Te mahi apūtau wahie MEA:
- Te wehewehe i ngā matū tauhohe: te ārai i te pā tika i waenga i te hauwai me te hāora.
- Ngā pūrotana kawe: ka taea e ngā pūrotana (H+) te haere mai i te anode mā roto i te kiriuhi ki te cathode.
- Ngā tauhohenga whakakorikori: Ka whakatairanga i te waikura hauwai i te anode me te whakaiti hāora i te cathode.
- Te whakaputa iahiko: ka puta te rere o te irahiko mā roto i ngā tauhohenga hikohiko.
- Te whakahaere i te wai: te pupuri i te taurite o te wai kia mau tonu ai ngā tauhohenga.
