I-vet-china izibophezele ekunikezeni izinto ezisebenza kahle zamaseli kaphethiloli, ikakhulukazi ulwelwesi lokushintshaniswa kwe-proton (PEM) le-fuel cell membrane electrode assembly (MEA). Lo mhlangano ukhiqizwa kusetshenziswa ubuchwepheshe obusha ukuze kuqinisekiswe ukusebenza kahle kwamasistimu amaseli kaphethiloli ezimeni ezihlukahlukene zokusetshenziswa, kusukela emandleni emoto kuya ezinhlelweni zamandla aphathwayo.
Imininingwane yokuhlanganiswa kwe-membrane electrode:
| Ubukhulu | awu 50m. |
| Osayizi | 5 cm2, 16 cm2, 25 cm2, 50 cm2 noma 100 cm2 izindawo ezisebenzayo. |
| I-Catalyst Iyalayisha | I-Anode = 0.5 mg Pt/cm2.Cathode = 0.5 mg Pt/cm2. |
| Izinhlobo zokuhlanganisa i-Membrane electrode | 3-ungqimba, 5-ungqimba, 7-ungqimba (ngakho ngaphambi koku-oda, sicela ucacise ukuthi zingaki izendlalelo ze-MEA ozikhethayo, futhi unikeze nomdwebo we-MEA). |
Isakhiwo esikhulu sefuel cell MEA:
a) I-Proton Exchange Membrane (PEM): ulwelwesi olukhethekile lwe-polymer phakathi nendawo.
b) Izendlalelo ze-Catalyst: nhlangothi zombili zolwelwesi, ngokuvamile ezakhiwe ngama-catalysts ensimbi ayigugu.
c) Izendlalelo Zokusabalalisa Igesi (GDL): ezinhlangothini zangaphandle zezingqimba ze-catalyst, ngokuvamile ezenziwe ngezinto ze-fiber.
Umsebenzi wefuel cell MEA:
- Ukuhlukanisa ama-reactants: kuvimbela ukuthintana okuqondile phakathi kwe-hydrogen nomoya-mpilo.
- Ukuqhuba ama-proton: kuvumela ama-proton (H+) ukuthi adlule esuka ku-anode adlule kulwelwesi aye ku-cathode.
- I-Catalyzing reactions: Ithuthukisa i-hydrogen oxidation ekunciphiseni kwe-anode kanye komoya-mpilo ku-cathode.
- Ukukhiqiza okwamanje: kukhiqiza ukugeleza kwe-electron ngokusabela kwe-electrochemical.
- Ukuphatha amanzi: kugcina ibhalansi yamanzi efanele ukuqinisekisa ukusabela okuqhubekayo.
