Amapuleti e-Bipolar(ama-BP) ayisici esibalulekile se-i-membrane yokushintshana kweprotoni (i-PEM)Amaseli kaphethiloli anesimo esisebenza ngezindlela eziningi. Asabalalisa igesi kaphethiloli nomoya ngendlela efanayo, aqhuba ugesi kusuka kuseli kuya kwelinye, asuse ukushisa endaweni esebenzayo, futhi avimbele ukuvuza kwamagesi kanye ne-coolant. Ama-BP nawo anegalelo elikhulu kumthamo, isisindo kanye nezindleko ze-PEM.izitaki zamaseli kaphethiloli.
Amapuleti e-Bipolarhlukanisa amagesi asabelayo bese uwasabalalisa ohlangothini ngalunye kuyo yonke indawo esebenzayo ye-MEA. Amapuleti e-bipolar asusa namagesi angasabelanga namanzi endaweni esebenzayo ye-MEA. Amapuleti e-bipolar kufanele abe nokulawula ugesi, amelane kakhulu namakhemikhali ezimweni zokusebenza, futhi alawule kakhulu ukufudumala ukuze kudluliselwe ukushisa okungcono kulo lonke iseli. Amapuleti e-bipolar ama-LT- kanye nama-HT-PEMFC enziwe ngezinto ezifanayo, kodwa izinto zepuleti le-bipolar le-HT-PEMFC kufanele zibekezelele amandla kagesi azinzile, indawo ephansi ye-pH kanye namazinga okushisa afinyelela ku-200°C. Kuyadingeka ukuthi amapuleti e-bipolar abe nokulawula ugesi nokushisa.
Eminye yale misebenzi ihlanganisa ukusatshalaliswa kukaphethiloli kanye ne-oxidant ngaphakathi kwamaseli, ukuhlukaniswa kwe-oAmaseli ahlukene, ukuqoqwa kwamandla kagesi akhiqizwayo, ukukhishwa kwamanzi kusuka kuseli ngayinye, umswakama wamagesi kanye nokupholisa kwamaseli. Amapuleti e-bipolar nawo aneziteshi ezivumela ukudlula kwama-reactants (uphethiloli kanye ne-oxidant) ohlangothini ngalunye. Akha izingxenye ze-anode kanye ne-cathode ezinhlangothini eziphambene zepuleti le-bipolar. Ukwakheka kweziteshi zokugeleza kungahluka; zingaba ziqondile, zigoqekile, zihambisane.
I-VET yipuleti le-bipolarmai-nufacturer ekhethekile ezingxenyeni zamaseli kaphethiloli asebenza kahle kakhuluabakhiqizi bemikhiqizo, abacwaningi kanye nabafundisi emhlabeni jikelele.Sithuthukise amapuleti e-graphite bipolar angabizi kakhulu ukuzeIseli likaphethiloli(PEMFC) okuyi-bipolar plates ethuthukisiwe enokuqhuba ugesi okuphezulu kanye namandla amahle okusebenza. Ama-bipolar plates avumela amaseli kaphethiloli ukuthi asebenze emazingeni okushisa aphezulu futhi abe nokuqhuba ugesi nokushisa okuhle kakhulu.
