Shiinuhu wuxuu bixiyaa unug shidaal haydarojiin ah oo tayo sare lehshirka elektroodka xuubkaxirmooyinka (MEAs) kuwaas oo bixiya waxqabad koronto-kiimiko oo heer sare ah iyo cimri dherer muddo dheer ah oo loogu talagalay nidaamyada kala duwan ee unugyada shidaalka haydarojiin.Unug Shidaal Haydarojiin ahQalabka Elektrode-ka XuubkaGolaha Koronto ee Xuubkawaxay isticmaashaa tiknoolajiyad casri ah si loo hubiyo in qayb kasta ay leedahay hufnaan sare oo beddelka tamarta ah, oo ku habboon xaalado kala duwan oo codsi ah laga bilaabo nidaamyada korontada gawaarida ilaa ilaha korontada la qaadi karo.
Faa'iidada ugu muhiimsan eeMEAwaxay ku jirtaa iska caabinta gudaha oo hooseysa iyo gudbis sare, taas oo si weyn u hagaajinaysa hufnaanta wax soo saarka korontadaUnug Shidaal Haydarojiin ahQalabka Elektrode-ka XuubkaGolaha Koronto ee XuubkaNaqshadeynta hal-abuurka leh ee vet-shiinaha waxay awood u siineysaa qaybaha inay si joogto ah ugu shaqeeyaan jawi shaqo oo adag sida cadaadis sare iyo heerkul sare, taasoo hubineysa hawlgalka joogtada ah ee hufan ee unugyada shidaalka.
Tilmaamaha isku-darka elektroodka xuubka:
| Dhumucda | 50 μm. |
| Cabbirrada | 5 cm2, 16 cm2, 25 cm2, 50 cm2 ama 100 cm2 meelaha dusha sare ee firfircoon. |
| Soo rarista Kataliska | Anode = 0.5 mg Pt/cm2. Katoodh = 0.5 mg Pt/cm2. |
| Noocyada isu-imaatinka elektroodka xuub-dhiska | 3-lakab, 5-lakab, 7-lakab (markaa ka hor intaadan dalban, fadlan cadee inta lakab ee MEA aad doorbidayso, oo sidoo kale bixi sawirka MEA). |
Qaab-dhismeedka ugu weyn eeMEA: unugyada shidaalka
a) Xuubka Isweydaarsiga Proton (PEM): xuub polymer gaar ah oo ku yaal bartamaha.
b) Lakabyada Kataliska: labada dhinac ee xuubka, badanaa waxay ka kooban yihiin kataliyayaasha birta qaaliga ah.
c) Lakabyada Fidinta Gaaska (GDL): dhinacyada dibadda ee lakabyada kiciyaha, oo badanaa laga sameeyo walxo faybar ah.
Faa'iidooyinka aanu ka helnoMEA unug shidaal:
- Tiknoolajiyada casriga ah:haysashada shatiyo badan oo MEA ah, oo si joogto ah u horseedaya horumarro;
- Tayo aad u fiican:Xakamaynta tayada adag waxay hubisaa isku halaynta MEA kasta;
- Habayn dabacsan:bixinta xalalka MEA ee shaqsiyeysan iyadoo loo eegayo baahiyaha macaamiisha;
- Xoogga R&D:iskaashi la samee jaamacado iyo machadyo cilmi baaris oo badan oo caan ah si loo ilaaliyo hoggaanka tignoolajiyada.
