Ultra-yakaonda graphite bipolar plate imhando yemhando yepamusoro-yemagetsi emagetsi, ayo anoshandiswa zvakanyanya mufuel cell nezvimwe.
Zvimiro uye zvakanakira
- High conductivity: Graphite pachayo ine yakanaka magetsi conductivity; inogona kutamisa ikozvino zvakanaka, kuderedza kurasikirwa kwekupikisa, kuvandudza simba rekushandura simba.
- Corrosion resistance: Graphite zvinhu zvine kugadzikana kwekemikari zvakanakisa, hazvisi nyore kuparadzwa munzvimbo dzakasiyana siyana dzeasidhi nealkali, zvinogona kuita kuti{0}}zvishande zvakagadzikana munzvimbo yakaoma yemagetsi emagetsi.
- High mechanical simba: ine inoratidzira yakakwana kuoma uye simba, iyo inogona kumira kumanikidziro panguva yekubatanidza bhatiri uye kushanda, uye inopa tsigiro yakagadzikana yemukati wemukati webhatiri.
- Dhizaini yakatetepa: Kuburikidza neruzivo rwepamusoro-soro, -mapuleti matete egraphite bipolar ane ukobvu kudiki anogona kugadzirwa, izvo zvinobatsira kudzikisa huremu uye huremu hwefuel cell stack uye kunatsiridza kushanda kwese.
Future development trends
Mutete (<0.3mm): Graphene-reinforced composite materials will be used to break through the thickness limit
3D kudhinda tekinoroji: kuumbwa kwakananga kwematanho ekuyerera kwakaoma uye kuderedzwa kwematanho ekugadzirisa.
Intelligent bipolar plate: yakasanganiswa sensors yekutarisa mamiriro emafuta cell munguva chaiyo.

Maitiro ekushandisa
- Fuel cell vehicles: Sechimwe chezvakakosha zvehydrogen fuel cell mota, kushandiswa kweultra-thin graphite bipolar plates kunogona kunatsiridza mashandiro uye huwandu hwemotokari.
- Fixed power stations: Muzviitiko zvakaita sedata centers ne communication base stations, inokwanisa kushandura simba zvine mutsindo nekuda kwekureba-kuramba corrosion.
- Electrolytic cell and reactor: Muindasitiri yechlor-alkali, inogona kushandiswa se electrode material ye electrolytic cell kushingirira asidhi yakasimba uye alkali nharaunda uye kurebesa hupenyu hwesevhisi yemidziyo.
- Mimwe minda: inogona zvakare kushandiswa mumasisitimu ekuchengetedza simba, kurapwa kwemvura yetsvina, kugadzirwa kwehydrogen uye kuchengetedza simba, photovoltaic nemimwe minda.
