Ipuleti le-bipolar liyingxenye eyinhloko ye-reactor, enomthelela omkhulu ekusebenzeni nasekubizeni kwe-reactor. Njengamanje, ipuleti le-bipolar lihlukaniswe kakhulu ngamapuleti e-graphite, amapuleti ahlanganisiwe kanye namapuleti ensimbi ngokwezinto ezibonakalayo.
Ipuleti le-bipolar lingenye yezingxenye eziyinhloko ze-PEMFC, indima yalo eyinhloko ukuthutha igesi ensimini yokugeleza kwamanzi, ukuqoqa nokuqhuba ugesi, ukushisa namanzi okukhiqizwa ukusabela. Kuye ngohlobo lwezinto ezibonakalayo, isisindo sesitaki se-PEMFCs singaba ngu-60% kuya ku-80% kanti izindleko zingaba ngu-30%. Ngokwezidingo zokusebenza kwepuleti le-bipolar, kanye nokucabangela indawo yokusabela kwe-electrochemical acidic ye-PEMFC, ipuleti le-bipolar liyadingeka ukuthi libe nezidingo eziphezulu zokuqhuba ugesi, ukuqina komoya, izakhiwo zemishini, ukumelana nokugqwala, njll.
Ipuleti eliphindwe kabili ngokwezinto zokwakha lihlukaniswe kakhulu ngezigaba ezintathu ipuleti le-graphite, ipuleti elihlanganisiwe, ipuleti lensimbi, ipuleti eliphindwe kabili le-graphite yilona elisetshenziswa kakhulu njengamanje ipuleti eliphindwe kabili le-PEMFC lasekhaya, ukuqhuba kukagesi, ukuqhuba kokushisa, ukuzinza okuhle kanye nokumelana nokugqwala kanye nokunye ukusebenza kodwa izakhiwo ezingezinhle zemishini, ukuphuka, ubunzima bokusebenza kuholela ezinkingeni zezindleko eziphakeme ezihlushwa abakhiqizi abaningi.
I-Graphiteipuleti le-bipolarIsingeniso:
Amapuleti e-bipolar enziwe nge-graphite anokuqhutshwa kahle kukagesi, ukuqhutshwa kokushisa kanye nokumelana nokugqwala, futhi angamapuleti e-bipolar asetshenziswa kakhulu ku-PEMFCS. Kodwa-ke, izinkinga zawo zisobala kakhulu: izinga lokushisa le-graphitization lepuleti le-graphite livame ukuba ngaphezu kuka-2500℃, okudingeka kwenziwe ngokwenqubo yokushisa eqinile, futhi isikhathi side; Inqubo yokugaya ihamba kancane, umjikelezo mude, futhi ukunemba komshini kuphakeme, okuholela ezindleko eziphezulu zepuleti le-graphite; I-Graphite iyaphuka, ipuleti eliqediwe lidinga ukuphathwa ngokucophelela, ukuhlanganiswa kunzima; I-Graphite inezimbobo, ngakho amapuleti kudingeka abe ngamamilimitha ambalwa ubukhulu ukuze kuvunyelwe amagesi ukuthi ahlukane, okuholela ekuxineni okuphansi kwezinto ngokwazo, kodwa kube umkhiqizo oqediwe osindayo.
Ukulungiswa kwe-graphiteipuleti le-bipolar：
Impuphu ye-toner noma ye-graphite ixutshwa ne-resin ene-graphitized, icindezelwe, futhi ifakwe i-graphitized ekushiseni okuphezulu (ngokuvamile ku-2200 ~ 2800C) emoyeni ophansi noma ngaphansi kwezimo ze-vacuum. Ngemuva kwalokho, ipuleti le-graphite liyafakwa ukuze livale imbobo, bese kusetshenziswa umshini wokulawula wezinombolo ukucubungula indlela edingekayo yegesi ebusweni bayo. UKUSHINTSHA KWE-GRAPHITIZATION OKUPHEZULU NOKUSHINTSHA KWEZISHINELELI ZEGESI KUYIZIZATHU EZIPHAMBILI ZEZINDLEKO EZIPHEZULU ZAMA-BIPOLAR PLATES, NGOKUBASHINTSHA KUBALWA cishe u-60% WEZINDLEKO ZONKE ZAMA-FUEL CELL.
Ipuleti le-Bipolaringenye yezingxenye eziyinhloko kakhulu esitokisini samaseli kaphethiloli. Imisebenzi yayo eyinhloko yilena elandelayo:
1, uxhumano lwebhethri olulodwa
2. Ukuletha uphethiloli (H2) nomoya (02)
3, Ukuqoqwa kwamanje kanye nokuqhuba
4, i-Support stack kanye ne-MEA
5. Ukususa ukushisa okubangelwa ukusabela
6. Khipha amanzi akhiqizwe ekuphenduleni
