I-vet-china izibophezele ekuhlinzekeni ngezinto ezisebenzayo zamaseli kaphethiloli, ikakhulukazi i-proton exchange membrane (PEM) fuel cell membrane electrode assembly (MEA). Le nhlangano ikhiqizwa kusetshenziswa ubuchwepheshe obusha ukuqinisekisa ukusebenza okuhle kakhulu kwezinhlelo zamaseli kaphethiloli ezimweni ezahlukahlukene zokusetshenziswa, kusukela emandleni ezimoto kuya ezinhlelweni zamandla eziphathwayo.
Imininingwane yokuhlanganiswa kwe-membrane electrode:
| Ubukhulu | 50 μm. |
| Osayizi | Izindawo ezisebenza phezulu ezingama-5 cm2, 16 cm2, 25 cm2, 50 cm2 noma eziyi-100 cm2. |
| Ukulayisha kwe-Catalyst | I-Anode = 0.5 mg Pt/cm2. I-Cathode = 0.5 mg Pt/cm2. |
| Izinhlobo zokuhlangana kwe-electrode ye-membrane | Izingqimba ezi-3, izingqimba ezi-5, nezingqimba ezi-7 (ngakho-ke ngaphambi koku-oda, sicela ucacise ukuthi zingaki izingqimba ze-MEA ozikhethayo, bese unikeza nomdwebo we-MEA). |
Isakhiwo esiyinhloko sei-MEA yeseli kaphethiloli:
a) I-Proton Exchange Membrane (PEM): i-polymer membrane ekhethekile phakathi nendawo.
b) Izingqimba ze-Catalyst: ezinhlangothini zombili ze-membrane, ngokuvamile zakhiwe ngama-catalyst ensimbi eyigugu.
c) Izingqimba Zokusabalalisa Igesi (GDL): ezinhlangothini zangaphandle zezingqimba ze-catalyst, ngokuvamile ezenziwe ngezinto zefayibha.
Umsebenzi wei-MEA yeseli kaphethiloli:
- Ukuhlukanisa ama-reactant: kuvimbela ukuxhumana okuqondile phakathi kwe-hydrogen ne-oxygen.
- Ukuqhuba ama-proton: kuvumela ama-proton (H+) ukuthi adlule esuka ku-anode nge-membrane aye ku-cathode.
- Ukusabela okubangela ukusheshisa: Kukhuthaza ukushiswa kwe-hydrogen ku-anode kanye nokunciphisa i-oxygen ku-cathode.
- Ukukhiqiza ugesi: kukhiqiza ukugeleza kwama-electron ngokusebenzisa ukusabela kwama-electrochemical.
- Ukuphatha amanzi: kugcina ibhalansi efanele yamanzi ukuqinisekisa ukusabela okuqhubekayo.
