i-vet-china izibophelele ekuboneleleni ngokufanelekileyo izixhobo zeseli ye-fuel, ngakumbi i-proton exchange membrane (PEM) i-fuel cell membrane electrode assembly (MEA). Le ndibano iveliswa kusetyenziswa ubuchwepheshe obutsha bokuqinisekisa ukusebenza kakuhle kweenkqubo zeeseli zamafutha kwiimeko ezahlukeneyo zokusetyenziswa, ukusuka kumandla ezithuthi ukuya kwiinkqubo zamandla aphathwayo.
Iinkcazo ze-membrane ye-electrode assembly:
| Ukutyeba | 50 μm. |
| Ubukhulu | 5 cm2, 16 cm2, 25 cm2, 50 cm2 okanye 100 cm2 iindawo ezisebenzayo. |
| I-Catalyst Iyalayisha | I-Anode = 0.5 mg Pt/cm2.Cathode = 0.5 mg Pt/cm2. |
| Iintlobo zendibano ye-Membrane electrode | I-3-layer, i-5-layer, i-7-layer (ngoko ngaphambi koku-odola, nceda ucacise ukuba zingaphi iileya ze-MEA ozikhethayo, kwaye unike umzobo we-MEA). |
Ulwakhiwo oluphambili lweiseli yamafutha MEA:
a) I-Proton Exchange Membrane (PEM): i-membrane ye-polymer ekhethekileyo kwiziko.
b) I-Catalyst Layers: kumacala omabini e-membrane, ngokuqhelekileyo iqulunqwe ngeentsimbi zentsimbi ezixabisekileyo.
c) I-Gas Diffusion Layers (GDL): kumacala angaphandle amacandelo e-catalyst, ngokuqhelekileyo ayenziwe ngezinto zefiber.
Umsebenzi weiseli yamafutha MEA:
- Ukwahlula ii-reactants: kuthintela ukudibana ngokuthe ngqo phakathi kwe-hydrogen kunye ne-oxygen.
- Ukuqhuba iiprotons: kuvumela iiprotoni (H +) ukuba zidlule kwi-anode nge-membrane ukuya kwi-cathode.
-I-catalyzing reactions: Ikhuthaza i-hydrogen oxidation kwi-anode kunye nokunciphisa i-oxygen kwi-cathode.
- Ukuvelisa okwangoku: kuvelisa ukuhamba kwe-electron ngokuphendula kwe-electrochemical reaction.
- Ukulawula amanzi: kugcina ulungelelwaniso lwamanzi olufanelekileyo ukuqinisekisa ukusabela okuzingileyo.
