Bipolar mbale, Bipolar mbale ya mafuta cell

Bipolar mbale(BPs) ndi gawo lofunikira laProton exchange membrane (PEM)ma cell amafuta omwe ali ndi mawonekedwe ambiri. Amagawa mofanana gasi ndi mpweya, amayendetsa magetsi kuchokera ku selo kupita ku selo, amachotsa kutentha pamalo omwe akugwira ntchito, ndikuletsa kutuluka kwa mpweya ndi ozizira. Ma BP amathandizanso kwambiri kuchuluka, kulemera ndi mtengo wa PEMmafuta cell stacks.

Bipolar mbalealekanitse mpweya wotulutsa mpweya ndikugawa mbali zonse kudera lonse logwira ntchito la MEA. Ma mbale a bipolar amachotsanso mpweya wosagwiritsidwa ntchito ndi madzi kuchokera kumalo ogwira ntchito a MEA. Ma mbale a bipolar akuyenera kukhala oyendera magetsi, osagwira ntchito ndi mankhwala, komanso otenthetsera kwambiri kuti azitha kutentha bwino pa selo. Ma mbale a bipolar a LT- ndi HT-PEMFC amapangidwa ndi zinthu pafupifupi zofanana, koma HT-PEMFC bipolar plate material iyenera kupirira mphamvu yamagetsi yokhazikika, malo otsika pH ndi kutentha kwa 200 ° C. Ndikofunikira kuti mbale za bipolar zikhale zamagetsi ndi thermally conductive.

Zina mwa ntchitozi zikuphatikizapo kugawa mafuta ndi okosijeni mkati mwa maselo, kulekanitsa of maselo osiyanasiyana, kusonkhanitsa kwa magetsi opangidwa, kutuluka kwa madzi ku selo iliyonse, kusungunuka kwa mpweya ndi kuzizira kwa maselo. Ma mbale a bipolar alinso ndi njira zomwe zimalola kuti ma reactants (mafuta ndi okosijeni) azidutsa mbali iliyonse. Amapanga zigawo za anode ndi cathode mbali zotsutsana za mbale ya bipolar. Mapangidwe a mayendedwe oyenda amatha kukhala osiyanasiyana; zikhoza kukhala zozungulira, zopindika, zofanana.

VET ndi mbale ya bipolarmanufacturer yomwe imagwira ntchito kwambiri pama cell amafuta amafutaopanga mankhwala, ofufuza ndi aphunzitsi padziko lonse lapansi.Tapanga mbale zotsika mtengo za graphite bipolarFuel Cell(PEMFC) yomwe ndi mbale zapamwamba za bipolar zokhala ndi magetsi apamwamba komanso mphamvu zamakina abwino. Ma mbale a bipolar amalola kuti ma cell amafuta azigwira ntchito kutentha kwambiri komanso kukhala ndi mphamvu yabwino kwambiri yamagetsi ndi matenthedwe.
