Mapepala a Bipolar

Mapepala a Bipolaramapangidwa ndi graphite kapena chitsulo; amagawa mafuta mofananaokosijeni ku maselo a selo yamafutaAmasonkhanitsanso magetsi opangidwa kuchokera ku magetsi omwe amatuluka m'malo otulutsira magetsi.

Mu selo imodzi yamafuta, mulibe mbale ya bipolar; komabe, pali mbale imodzi yomwe imaperekakuyenda kwa ma elekitironiMu maselo amafuta omwe ali ndi maselo oposa limodzi, pali mbale imodzi ya bipolar (kulamulira kayendedwe ka madzi kumakhala mbali zonse ziwiri za mbale). Mapepala a bipolar amapereka ntchito zingapo mu selo yamafuta.

Zina mwa ntchitozi ndi monga kugawa mafuta ndi okosijeni mkati mwa maselo, kulekanitsa maselo osiyanasiyana, ndi kusonkhanitsamphamvu yamagetsizomwe zimapangidwa, 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. Amapangidwa.magawo a anode ndi cathodembali zosiyana za mbale ya bipolar. Kapangidwe ka njira zoyendetsera madzi kangasiyane; kangakhale kolunjika, kozungulira, kofanana, kofanana ndi chipeso kapena kotalika mofanana monga momwe chithunzi chili pansipa chikusonyezera.

Mitundu yosiyanasiyana ya bipolar plate [COL 08]. a) Njira zoyendera zozungulira; b) njira zambiri zoyendera zozungulira; c) njira zoyendera zozungulira; d) njira zoyendera zozungulira

Zipangizozo zimasankhidwa kutengerakugwirizana kwa mankhwala, kukana dzimbirimtengo,kuyendetsa magetsi, kuthekera kofalitsa mpweya, kusalowa madzi, kusavuta kugwiritsa ntchito makina, mphamvu ya makina ndi kutentha kwawo.
