Takagadzira mahwendefa e graphite bipolar anodhura ayo anoda kushandiswa kwema plates epamusoro ebipolar ane high conductivity yemagetsi uye simba rakanaka remuchina. Iyo inonatswa ne-high-pressure kuumba, vacuum impregnation, uye yakakwirira-tembiricha kupisa kurapwa, bipolar plate yedu ine hunhu hwekupfeka kuramba, tembiricha kuramba, kumanikidza kuramba, corrosion resistance, creep resistance, oiri-isina self-lubrication, diki yekuwedzera coefficient, uye yepamusoro yekuisa chisimbiso.
Tinokwanisa kuchina mahwendefa ebipolar pamativi ese ane minda yekuyerera, kana muchina mumwechete divi kana kupa mahwendefa asina kugadzirwa zvakare. Ese mahwendefa egraphite anogona kugadzirwa sekuenderana nedhizaini yako.

| Anti-knock performance test | Iwo mapendero mana eplate akakiyiwa ne torque wrench pasi pemamiriro e13NM, uye kamuri yekutonhodza inomanikidzwa nemhepo inotsikirira≥ 4.5kg (0.45MPa), ndiro haizotambanudzirwe yakavhurika kuti ibude mweya. |
Zvakanakira bipolar plate yedu:
1. Ultra-yakakwirira conductivity, kubatsira kushanda nesimba kutendeuka
High-purity graphite ≥99.9%, conductivity kusvika ku150 S / cm, kuve nechokwadi chekurasikirwa kwezero mukufambisa kwemazuva ano.
Low contact resistance: Iyo yepamusoro yakakwenenzverwa padanho re nano, uye kupikisa kwekubata negasi diffusion layer ndeye ≤10mΩ · cm², iyo inovandudza kubuda kwesimba remafuta sero.
2. Yakanyanya kusimba kushorwa kwekudzivirira, kuchinjika kune dzakaoma nharaunda
Yakanakisa kugadzikana kwemakemikari: Inogona kumira yakasimba acids (senge phosphoric acid), yakasimba alkalis uye tembiricha yepamusoro uye yakakwirira humidity nharaunda, pasina simbi ion kunaya.
Anti-oxidation coating technology (optional): Silicon carbide (SiC) inodzivirira layer inowedzerwa kuburikidza neCVD process, uye hupenyu hurefu hunowedzerwa nekanopfuura 3 nguva.
3. Lightweight design, kuderedza kushandiswa kwesimba rehurongwa
Density yakadzikira se1.8 g/cm3: 20% yakareruka pane simbi bipolar plates, yakakodzera kune uremu-sensitive scenarios senge mota-yakaiswa mafuta maseru.
Mutete chimiro: Ukobvu hunogona kugadziridzwa kusvika 0.8.0-2.0mm, optimize stacking nzvimbo uye kuvandudza simba density.
4. Hupenyu hurefu uye mutengo wakaderera wekuchengetedza
Flexural simba ≥ 40 MPa: Yakanakisa mechanical kukanganisa kuramba, kudzivirira brittle kuputsika.
Creep resistance: Kuenderera mberi kwekushanda kwe10,000 maawa pa80 ℃ uye 95% humidity, kukanganisa kwekuita <5%.
Ningbo VET Energy Technology Co., Ltd ibhizimusi repamusoro-soro rinotarisa mukusimudzira nekugadzirwa kwezvinhu zvepamusoro-soro, zvekushandisa uye tekinoroji zvinosanganisira graphite, silicon carbide, ceramics, kurapwa kwepamusoro seSiC coating, TaC coating, girazi kabhoni coating, pyrolytic kabhoni coating, nezvimwewo, zvigadzirwa izvi zvinoshandiswa zvakanyanya muphotovoltaic, semiconductor itsva, semicondurgy.
Chikwata chedu chehunyanzvi chinobva kumasangano epamusoro ekutsvagisa edzimba, uye akagadzira akawanda ematekinoroji matekinoroji ekuona kuita kwechigadzirwa uye mhando, anogona zvakare kupa vatengi mhinduro dzehunyanzvi.
