vet-china tau cog lus tias yuav muab cov khoom siv roj teeb zoo, tshwj xeeb tshaj yog proton exchange membrane (PEM) roj teeb electrode assembly (MEA). Lub rooj sib txoos no yog tsim los ntawm kev siv cov thev naus laus zis tshiab los xyuas kom meej tias cov roj teeb ua haujlwm zoo hauv ntau yam kev siv, los ntawm lub zog tsheb mus rau cov tshuab hluav taws xob nqa tau.
Cov lus qhia ntawm lub rooj sib txoos electrode membrane:
| Qhov tuab | 50 μm. |
| Qhov Loj | 5 cm2, 16 cm2, 25 cm2, 50 cm2 lossis 100 cm2 cov cheeb tsam nto nquag. |
| Catalyst Loading | Anode = 0.5 mg Pt/cm2. Cathode = 0.5 mg Pt/cm2. |
| Cov hom sib dhos electrode membrane | 3-txheej, 5-txheej, 7-txheej (yog li ua ntej xaj, thov qhia meej tias koj nyiam pes tsawg txheej MEA, thiab muab daim duab MEA). |
Lub ntsiab qauv ntawmroj cell MEA:
a) Proton Exchange Membrane (PEM): ib daim polymer membrane tshwj xeeb nyob hauv nruab nrab.
b) Cov Txheej Txheem Catalyst: ntawm ob sab ntawm daim nyias nyias, feem ntau yog tsim los ntawm cov hlau muaj nqis catalysts.
c) Cov Txheej Txheem Gas Diffusion (GDL): nyob rau sab nraud ntawm cov txheej catalyst, feem ntau yog ua los ntawm cov ntaub ntawv fiber.
Lub luag haujlwm ntawmroj cell MEA:
- Kev sib cais cov tshuaj reactants: tiv thaiv kev sib cuag ncaj qha ntawm hydrogen thiab oxygen.
- Kev coj cov protons: tso cai rau cov protons (H +) hla dhau ntawm qhov anode los ntawm daim nyias nyias mus rau cathode.
- Cov tshuaj tiv thaiv catalyzing: Txhawb kev oxidation hydrogen ntawm qhov anode thiab txo cov pa oxygen ntawm cathode.
- Tsim cov hluav taws xob: tsim cov hluav taws xob ntws los ntawm cov tshuaj electrochemical.
- Kev tswj dej: tswj kom muaj dej sib npaug zoo kom ntseeg tau tias muaj kev cuam tshuam tas mus li.
