vet-china tau cog lus los muab cov khoom siv roj hluav taws xob zoo, tshwj xeeb tshaj yog cov khoom siv hluav taws xob sib txuas (PEM) roj cell membrane electrode los ua ke (MEA). Lub rooj sib txoos no yog tsim los siv cov thev naus laus zis tshiab los xyuas kom meej qhov ua tau zoo ntawm cov roj hluav taws xob hauv ntau qhov kev thov, los ntawm lub zog tsheb mus rau lub zog hluav taws xob.
Specifications ntawm membrane electrode los ua ke:
| Thickness | 50m ua. |
| Qhov ntau thiab tsawg | 5 cm2, 16 cm2, 25 cm2, 50 cm2 los yog 100 cm2 active nto thaj chaw. |
| Catalyst Loading | Anode = 0.5 mg Pt/cm2.Cathode = 0.5 mg Pt/cm2. |
| Membrane electrode los ua ke hom | 3-txheej, 5-txheej, 7-txheej (yog li ua ntej xaj, thov qhia meej pes tsawg txheej MEA koj nyiam, thiab tseem muab MEA daim duab). |
Lub ntsiab qauv ntawmFuel Cell MEA:
a) Proton Exchange Membrane (PEM): tshwj xeeb polymer membrane nyob rau hauv qhov chaw.
b) Catalyst Layers: ntawm ob sab ntawm daim nyias nyias, feem ntau yog tsim los ntawm cov khoom siv hlau zoo nkauj.
c) Gas Diffusion Layers (GDL): nyob rau sab nraud ntawm cov txheej txheem catalyst, feem ntau yog ua los ntawm cov ntaub ntawv fiber ntau.
Kev ua haujlwm ntawmFuel Cell MEA:
- Separating reactants: tiv thaiv kev sib cuag ncaj qha ntawm hydrogen thiab oxygen.
- Ua cov protons: tso cai rau cov protons (H +) dhau los ntawm cov anode los ntawm daim nyias nyias mus rau cathode.
- Cov tshuaj tiv thaiv catalyzing: Txhawb hydrogen oxidation ntawm anode thiab oxygen txo ntawm cathode.
- Tsim tam sim no: tsim hluav taws xob ntws los ntawm cov tshuaj tiv thaiv electrochemical.
- Tswj dej: tswj cov dej kom zoo kom muaj kev cuam tshuam tas mus li.
