vet-china waxaa ka go'an in ay bixiso agabka unugyada shidaalka oo hufan, gaar ahaan proton exchange xuubka (PEM) xuubka unugyada elektiroonigga ah (MEA). Kulankaan waxaa lagu soo saaray iyadoo la adeegsanayo tignoolajiyada hal-abuurka leh si loo hubiyo waxqabadka ugu wanaagsan ee nidaamyada unugyada shidaalka ee xaaladaha kala duwan ee codsiyada, laga bilaabo awoodda baabuurta ilaa nidaamyada tamarta la qaadan karo.
Tilmaamaha isu-ururinta korantada xuubka:
| Dhumucda | 50 μm |
| Cabbirrada | 5 cm2, 16 cm2, 25 cm2, 50 cm2 ama 100 cm2 meelaha sare ee firfircoon. |
| Soodejinta kicinta | Anode = 0.5 mg Pt/cm2.Cathode = 0.5 mg Pt/cm2. |
| Noocyada isku dhafka korantada xuubka | 3-lakab, 5-lakab, 7-lakab ah (sidaa darteed ka hor intaadan dalban, fadlan cadee inta lakab ee MEA aad doorbidayso, sidoo kale bixi sawirka MEA). |
Qaab dhismeedka ugu weyn eeunugga shidaalka MEA:
a) Membrane Proton Exchange Membrane (PEM): xuub polymer gaar ah oo ku yaal bartamaha.
b) Lakabyada kicinta: labada dhinac ee xuubka, oo inta badan ka kooban birta qaaliga ah.
c) Lakabyada faafinta gaaska (GDL): ee dhinacyada dibadda ee lakabyada kicinta, oo caadi ahaan ka samaysan walxaha fiber-ka.
Shaqada eeunugga shidaalka MEA:
- Kala saarista falceliyeyaasha: waxay ka hortagtaa xidhiidhka tooska ah ee u dhexeeya hydrogen iyo oxygen.
- Samaynta protons: waxay u ogolaataa protons (H+) inay ka gudbaan anode-ka iyada oo loo marayo xuubka ilaa cathode.
- Falcelinta kicinta: Waxay kor u qaadaa oksijiinta hydrogen at anode iyo dhimista oksijiinta ee cathode.
- Curinta hadda: waxay soo saartaa qulqulka elektarooniga ah iyada oo loo marayo falcelinta korantada.
- Maareynta biyaha: waxay ilaalisaa dheelitirka biyaha ee saxda ah si loo xaqiijiyo falcelinta joogtada ah.
