Iipleyiti zeBipolar(iiBPs) yinxalenye ephambili yeiproton exchange membrane (PEM)iiseli zamafutha ezinophawu lwemisebenzi emininzi. Basasaza ngokulinganayo irhasi yamafutha kunye nomoya, baqhube umbane ukusuka kwiseli ukuya kwiseli, basuse ubushushu kwindawo esebenzayo, kwaye banqande ukuvuza kweegesi kunye nokupholisa. IiBP nazo zinegalelo elikhulu kumthamo, ubunzima kunye neendleko zePEMimfumba yeeseli zamafutha.
Iipleyiti zeBipolarzahlula iigesi ezisabelayo kwaye uzisasaze kwicala ngalinye phezu kwendawo yonke esebenzayo ye-MEA. Iipleyiti ze-bipolar nazo zisusa iigesi ezingaphendulwanga kunye namanzi kwindawo esebenzayo ye-MEA. Iipleyiti ze-bipolar kufuneka zilawuleke ngombane, zixhathise kakhulu ngokwekhemikhali kwiimeko zokusebenza, kwaye ziqhube ngokushushu ngokugqithiselayo ubushushu kwiseli. Iipleyiti ze-bipolar ze-LT- kunye ne-HT-PEMFCs zenziwe ngemathiriyeli ephantse ifane, kodwa imathiriyeli ye-bipolar plate ye-HT-PEMFC kufuneka inyamezele amandla ombane azinzileyo, indawo ephantsi ye-pH kunye namaqondo obushushu afikelela kuma-200°C. Kuyimfuneko ukuba iipleyiti ze-bipolar zisebenza ngombane kunye ne-thermal conductive.
Eminye yale misebenzi ibandakanya ukuhanjiswa kwamafutha kunye ne-oxidant ngaphakathi kweeseli, ukwahlula of iiseli ezahlukeneyo, ingqokelela yombane oveliswayo, ukukhutshwa kwamanzi kwiseli nganye, ukufumisa iigesi kunye nokupholisa kweeseli. Iipleyiti ze-bipolar nazo zineendlela ezivumela ukuhamba kwee-reactants (i-fuel kunye ne-oxidant) kwicala ngalinye. Benza i-anode kunye ne-cathode compartments kumacala ahlukeneyo kwi-bipolar plate. Uyilo lwemijelo yokuhamba lunokwahluka; zisenokuba ngumgca, zibhijene, zingqamane.
I-VET yipleyiti ye-bipolarmai-nufacturer egxile ekusebenzeni okuphezulu kumacandelo eseli yamafutha esikoabavelisi beemveliso, abaphandi kunye nabafundisi kwihlabathi jikelele.Senze iipleyiti zegraphite bipolar ezingabizi kakhuluIseli yamafutha(PEMFC) ehambele phambili iipleyiti ze-bipolar ezine-conductivity ephezulu yombane kunye namandla alungileyo omatshini. Iipleyiti ze-bipolar zivumela iiseli ze-fuel ukuba zisebenze kumaqondo obushushu aphezulu kwaye zibe ne-conductivity egqwesileyo yombane kunye ne-thermal.
