Twakoze plaque za graphite bipolar zihendutse kandi zisaba gukoresha plaque za bipolar zigezweho zifite amashanyarazi menshi kandi zifite imbaraga nyinshi za mekanike. Zitunganywa binyuze mu gukora umuvuduko mwinshi, imyuka ivamo umwuka, no gutunganya ubushyuhe bwinshi, plaque yacu ya bipolar ifite imiterere yo kudashira, kudashira ubushyuhe, kudashira, kudashira, kwisiga amavuta nta mavuta, ingano nto yo kwaguka, no gukora neza cyane.
Dushobora gukoresha ibyuma bya bipolar plates ku mpande zombi dukoresheje imirima y'amazi, cyangwa uruhande rumwe rw'imashini cyangwa se tugatanga ibyuma bidafite imashini. Amasahani yose ya grafiti ashobora gukoreshwa hakurikijwe igishushanyo mbonera cyawe.
Ibipimo bya tekiniki

| Ubucucike | 1.8-2.0 g/cm³ |
| Imbaraga zo koroha | ＞50MPa |
| Ubudahangarwa bw'aho umuntu ahuriye n'aho ahuriye | ≤6 mΩ·cm² |
| Ubushyuhe bwo gukora | -40℃~180℃ |
| Ubudahangarwa bw'inkongi | Irimo 0.5M H₂SO₄ mu gihe cy'amasaha 1000, kugabanya ibiro <0.1% |
| Ubunini buke | 0.8mm |
| Ikizamini cy'ubushyuhe bw'umwuka | Gushyira igitutu ku cyumba gikonjeshaho 1KG (0.1MPa), nta gusohoka kw'amazi mu cyumba cya hydrogen, icyumba cya ogisijeni n'icyumba cyo hanze. |
| Ikizamini cy'imikorere yo kurwanya gukomanga | Impande enye z'ikibaho zifunze hakoreshejwe icyuma gikonjesha gifite imiterere ya 13N.M, kandi icyumba gikonjesha gifite umuvuduko w'umwuka ≥ 4.5kg (0.45MPa), ikibaho ntikizapfunduka kugira ngo umwuka ufunguke. |
Ibyiza by'ingenzi bya bipolar plate yacu:
1. Ubushobozi bwo gutwara ingufu buri hejuru cyane, bufasha mu guhindura ingufu neza
Grafiti ifite ubuziranenge bwinshi ≥99.9%, ikora neza kugeza kuri 150 S/cm, bigatuma nta gihombo kirimo mu ihererekanya ry'amashanyarazi.
Ubudahangarwa buke bwo gukoraho: Ubuso burasa neza ku rwego rwa nano, kandi ubudahangarwa bwo gukoraho hamwe n'urwego rwo gukwirakwiza gaze ni ≤10mΩ·cm², ibyo bikaba byongera imbaraga zo gusohora lisansi.
2. Irwanya ingese cyane, ishobora guhangana n'ibidukikije bikomeye
Ituje cyane mu by’imiti: Ishobora kwihanganira aside zikomeye (nka aside fosforike), alkali zikomeye n’ahantu hashyuha cyane n’ubushyuhe bwinshi, nta mvura ya iyoni z’icyuma igwa.
Ikoranabuhanga ryo gusiga irangi rirwanya ogisijeni (ni ngombwa): Urukuta rwa silicon carbide (SiC) rwongerwaho binyuze mu nzira ya CVD, kandi igihe cyo kubaho cyongerwaho inshuro zirenga 3.
3. Igishushanyo mbonera cyoroheje, kigabanya ikoreshwa ry'ingufu mu buryo
Ubucucike buri hasi ya 1.8 g/cm3: 20% byoroheje ugereranyije na plaque z'icyuma zihindura imiterere y'ibintu, zikwiriye ibintu bishobora kwangirika nk'ibinyabiziga bikoresha lisansi.
Imiterere yoroheje: Ubunini bushobora guhindurwa kuri 0.8.0-2.0mm, bigatuma umwanya wo gukusanya urushaho kuba mwiza kandi bukongera ubucucike bw'ingufu.
4. Kuramba igihe kirekire no kugabanya ikiguzi cyo kubungabunga
Imbaraga zo koroha ≥ 40 MPa: Irwanya cyane ingaruka za mekanike, yirinda kuvunika nabi.
Ubudahangarwa bw'amazi: Ikoreshwa ry'amasaha 10.000 ku bushyuhe bwa 80°C na 95% by'ubushuhe, imikorere yayo ikagabanuka <5%.
Ningbo VET Energy Technology Co., Ltd ni ikigo gikoresha ikoranabuhanga rihanitse cyibanda ku iterambere n'umusaruro w'ibikoresho bigezweho, ibikoresho n'ikoranabuhanga birimo grafiti, silicon carbide, ceramics, gutunganya ubuso nko gusiga SiC, gusiga TaC, gusiga karuboni ikirahure, gusiga karuboni ikoze muri pyrolytic, nibindi, ibi bicuruzwa bikoreshwa cyane mu gusiga photovoltaic, semiconductor, ingufu nshya, metallurgy, nibindi.
Itsinda ryacu rya tekiniki rikomoka mu bigo bikomeye by’ubushakashatsi mu gihugu, kandi ryakoze ikoranabuhanga ryihariye rijyanye n’ibiciro kugira ngo rirebe ko ibicuruzwa bikora neza kandi bifite ireme, rishobora kandi guha abakiriya ibisubizo by’ibikoresho by’umwuga.
