Iiplate zeBipolar(iiBP) yinxalenye ebalulekileyo yei-membrane yokutshintshiselana kweproton (i-PEM)Iiseli zepetroli ezinemisebenzi emininzi. Zisasaza igesi yepetroli nomoya ngokulinganayo, ziqhuba umbane ukusuka kwiseli ukuya kwenye, zisusa ubushushu kwindawo esebenzayo, kwaye zithintela ukuvuza kweegesi kunye ne-coolant. Ii-BP zikwanegalelo elikhulu kumthamo, ubunzima kunye nexabiso le-PEM.ii-fuel cell stacks.
Iiplate zeBipolarYahlula iigesi ezisabelayo kwaye uzisasaze kwicala ngalinye kuyo yonke indawo esebenzayo ye-MEA. Iiplate ze-Bipolar zikwasusa iigesi ezingasabelanga kunye namanzi kwindawo esebenzayo ye-MEA. Iiplate ze-Bipolar kufuneka ziqhube umbane, zimelane kakhulu neekhemikhali kwiimeko zokusebenza, kwaye ziqhube ubushushu kakhulu ukuze kudluliselwe ubushushu ngcono kwiseli. Iiplate ze-Bipolar ze-LT- kunye ne-HT-PEMFC zenziwe ngezinto ezifanayo, kodwa izinto zeplate ye-bipolar ye-HT-PEMFC kufuneka zinyamezele amandla ombane azinzileyo, indawo ene-pH ephantsi kunye namaqondo obushushu afikelela kwi-200°C. Kufuneka ukuba iiplate ze-bipolar ziqhube umbane kunye nobushushu.
Eminye yale misebenzi ibandakanya ukusasazwa kwefutha kunye ne-oxidant ngaphakathi kweeseli, ukwahlukanaiiseli ezahlukeneyo, ukuqokelelwa kombane oveliswayo, ukukhutshwa kwamanzi kwiseli nganye, ukufuma kweegesi kunye nokupholisa iiseli. Iiplate zeBipolar nazo zinemijelo evumela ukudlula kwee-reactants (ipetroli kunye ne-oxidant) kwicala ngalinye. Zenza i-anode kunye ne-cathode compartments kumacala ahlukeneyo eplate ye-bipolar. Uyilo lwemijelo yokuhamba kwamanzi lunokwahluka; lunokuba luthe tyaba, lubhijelwe, luhambelane.
I-VET yiplate ye-bipolarmai-nufacturer ekhethekileyo kwizixhobo ze-fuel cell ezisebenza kakuhle kakhuluabavelisi bemveliso, abaphandi kunye nabafundisi-ntsapho kwihlabathi liphela.Siye senza iiplate ze-graphite bipolar ezingabizi kakhulu ukuzeIseli yepetroli(PEMFC) eyi-bipolar plates ephucukileyo enombane ophezulu kunye namandla amahle oomatshini. Ii-bipolar plates zivumela ii-fuel cells ukuba zisebenze kumaqondo obushushu aphezulu kwaye zine-electrical kunye ne-thermal conductivity egqwesileyo.
