vet-china yakazvipira kupa inoshanda mafuta esero zvinhu, kunyanya proton exchange membrane (PEM) mafuta cell membrane electrode assembly (MEA). Iyi gungano inogadzirwa pachishandiswa tekinoroji yehunyanzvi kuti ive nechokwadi chekushanda kwakanaka kwemafuta emafuta masisitimu mune dzakasiyana siyana dzekushandisa, kubva kumagetsi emotokari kuenda kune inotakurika magetsi masisitimu.
Zvinotsanangurwa zve membrane electrode kusangana:
| Ukobvu | 50 μm. |
| Saizi | 5 cm2, 16 cm2, 25 cm2, 50 cm2 kana 100 cm2 nzvimbo dzinoshanda dzepamusoro. |
| Catalyst Loading | Anode = 0.5 mg Pt/cm2.Cathode = 0.5 mg Pt/cm2. |
| Membrane electrode ungano mhando | 3-layer, 5-layer, 7-layer (saka usati wahodha, ndapota tsanangura kuti mangani akaturikidzana MEA aunoda, uye zvakare ipa iyo MEA dhizaini). |
Chimiro chikuru chemafuta sero MEA:
a) Proton Exchange Membrane (PEM): yakakosha polymer membrane iri pakati.
b) Catalyst Layers: pamativi ese ari maviri e membrane, kazhinji anoumbwa neakakosha simbi catalysts.
c) Gasi Diffusion Layers (GDL): pamativi ekunze ematanho anokonzeresa, anowanzo gadzirwa nefiber zvinhu.
Basa remafuta sero MEA:
-Kupatsanura reactants: inodzivirira kusangana kwakananga pakati pehydrogen neokisijeni.
- Kuitisa mapurotoni: inobvumira maproton (H +) kupfuura kubva kune anode kuburikidza ne membrane kuenda kune cathode.
- Catalyzing reactions: Inosimudzira hydrogen oxidation pane anode uye kuderedzwa kweokisijeni pane cathode.
- Kugadzira ikozvino: inogadzira maerekitironi kuyerera kuburikidza ne electrochemical reaction.
-Kugadzirisa mvura: inochengetedza mvura yakaringana kuti ive nechokwadi chekuenderera mberi.
