Mbale ya Bipolar, Mbale ya Bipolar ya cell yamafuta

Mapepala a Bipolar(BP) ndi gawo lofunika kwambiri lanembanemba yosinthira mapulotoni (PEM)Ma cell amafuta okhala ndi ntchito zambiri. Amagawa mpweya wamafuta ndi mpweya mofanana, amayendetsa magetsi kuchokera ku selo kupita ku selo, amachotsa kutentha pamalo ogwirira ntchito, komanso amaletsa kutuluka kwa mpweya ndi choziziritsira. Ma BP amathandiziranso kwambiri pa kuchuluka, kulemera ndi mtengo wa PEM.milu ya maselo amafuta.

Mapepala a BipolarLekanitsani mpweya woyambitsa ma reactant ndikuugawa mbali zonse ziwiri pa malo onse ogwira ntchito a MEA. Ma Bipolar plates amachotsanso mpweya ndi madzi osakhudzidwa kuchokera ku malo ogwira ntchito a MEA. Ma Bipolar plates ayenera kukhala opereka mphamvu zamagetsi, osagwirizana ndi mankhwala kwambiri ku mikhalidwe yogwirira ntchito, komanso opereka mphamvu kutentha kwambiri kuti kutentha kusamutsidwe bwino kudutsa selo. Ma Bipolar plates a LT- ndi HT-PEMFCs amapangidwa ndi zinthu zofanana, koma zinthu za HT-PEMFC bipolar plate ziyenera kukhala ndi mphamvu zamagetsi yokhazikika, pH yochepa komanso kutentha mpaka 200°C. Ndikofunikira kuti ma bipolar plates akhale opereka mphamvu zamagetsi komanso kutentha.

Zina mwa ntchitozi ndi monga kugawa mafuta ndi okosijeni mkati mwa maselo, kulekanitsa oMa cell osiyanasiyana, kusonkhanitsa kwa magetsi opangidwa, kutuluka kwa madzi kuchokera mu selo iliyonse, kunyowetsa mpweya ndi kuzizira kwa maselo. Ma bipolar plates alinso ndi njira zomwe zimalola kuti ma reactants (mafuta ndi okosijeni) adutse mbali iliyonse. Amapanga anode ndi cathode compartments mbali zosiyana za bipolar plate. Kapangidwe ka njira zoyendera madzi kangasiyane; akhoza kukhala olunjika, ozungulira, ofanana.

VET ndi mbale ya bipolarmanufacturer yomwe imagwira ntchito bwino kwambiri popanga zinthu zama cell amafuta opangidwa mwapadera kutiopanga zinthu, ofufuza ndi aphunzitsi padziko lonse lapansi.Tapanga ma graphite bipolar plates osawononga ndalama zambiri kuti agwiritsidwe ntchito pochiza matenda a mtima.Selo ya Mafuta(PEMFC) yomwe ndi ma bipolar plates apamwamba okhala ndi mphamvu zamagetsi zambiri komanso mphamvu zabwino zamakaniko. Ma bipolar plates amalola ma fuel cell kugwira ntchito kutentha kwambiri ndipo ali ndi mphamvu zamagetsi komanso kutentha kwambiri.
