Lipoleiti tsa bipolar(BP) ke karolo ea bohlokoa ealera la phapanyetsano ea proton (PEM)Lisele tsa mafura tse nang le sebopeho sa mesebetsi e mengata. Li aba khase ea mafura le moea ka ho lekana, li tsamaisa motlakase ho tloha seleng ho ea ho sele, li tlosa mocheso sebakeng se sebetsang, 'me li thibela ho lutla ha likhase le sehatsetsi. Li-BP li boetse li kenya letsoho haholo bophahamong, boima le litšenyehelo tsa PEM.li-stack tsa lisele tsa mafura.
Lipoleiti tsa bipolarArola likhase tse etsang hore ho be le karabelo 'me u li abele ka lehlakoreng le leng holim'a sebaka sohle se sebetsang sa MEA. Lipoleiti tsa bipolar li boetse li tlosa likhase tse sa arajoang le metsi sebakeng se sebetsang sa MEA. Lipoleiti tsa bipolar li lokela ho tsamaisa motlakase, li hane lik'hemik'hale haholo maemong a ts'ebetso, 'me li tsamaisa mocheso haholo bakeng sa phetisetso e ntle ea mocheso ho pholletsa le sele. Lipoleiti tsa bipolar bakeng sa li-LT- le HT-PEMFC li entsoe ka thepa e batlang e tšoana, empa thepa ea poleiti ea bipolar ea HT-PEMFC e tlameha ho mamella matla a motlakase a tsitsitseng, tikoloho e tlase ea pH le mocheso o fihlang ho 200°C. Ho hlokahala hore lipoleiti tsa bipolar li tsamaise motlakase le mocheso.
Mesebetsi e meng ena e kenyelletsa kabo ea mafura le oxidant ka hare ho lisele, karohano eaDisele tse fapaneng, pokello ya motlakase o hlahiswang, ho ntshuwa ha metsi seleng ka nngwe, ho kolobisa dikhase le ho phodisa disele. Dipoleiti tsa bipolar le tsona di na le dikanale tse dumellang ho feta ha di-reactant (mafura le oxidant) ka lehlakoreng ka leng. Di bopa dikarolwana tsa anode le cathode mahlakoreng a fapaneng a poleiti ya bipolar. Moralo wa dikanale tsa phallo o ka fapana; di ka ba tse otlolohileng, tse kobehileng, tse bapileng.
VET ke poleiti ea bipolarmanufacturer e ikhethang ka likarolo tsa sele ea mafura tse ikhethileng tse sebetsang hantle bakeng sabahlahisi ba lihlahisoa, bafuputsi le barupeli lefatšeng ka bophara.Re thehile lipoleiti tsa bipolar tsa graphite tse theko e tlaase bakeng saSele ea Mafura(PEMFC) e leng lipoleiti tse tsoetseng pele tsa bipolar tse nang le motlakase o phahameng le matla a matle a mechini. Lipoleiti tsa bipolar li lumella lisele tsa mafura ho sebetsa mochesong o phahameng 'me li na le motlakase o motle le mocheso o phahameng.
