Nā papa bipolar(BPs) he mea nui oʻO ka membrane hoʻololi proton (PEM)wahie me ke ano multifunctional. Hāʻawi like lākou i ke kinoea wahie a me ka ea, e hoʻokele i ka uila mai ke kelepona a i ke kelepona, e hoʻoneʻe i ka wela mai ka wahi hana, a pale i ka leakage o nā kinoea a me nā mea hoʻomaha. Hāʻawi nui nā BP i ka nui, ke kaumaha a me ke kumukūʻai o PEMwahie cell ahu.
Nā papa bipolare hoʻokaʻawale i nā kinoea reactant a e puʻunaue iā lākou ma kēlā me kēia ʻaoʻao ma luna o ka wahi hana holoʻokoʻa o ka MEA. Hoʻopau pū nā papa bipolar i nā kinoea a me ka wai i hana ʻole ʻia mai ka wahi hana o ka MEA. Pono nā pā bipolar e hoʻoheheʻe uila, kūpaʻa kemika i nā kūlana hana, a me ka wela wela no ka hoʻololi ʻana i ka wela ma waena o ke kelepona. Hana ʻia nā papa bipolar no LT- a me HT-PEMFC me nā mea like like, akā pono ʻo HT-PEMFC bipolar plate material e hoʻomanawanui i kahi pono uila paʻa, kahi pH haʻahaʻa a me nā mahana a hiki i 200°C. Pono nā papa bipolar e hoʻoheheʻe i ka uila a me ka thermally conductive.
ʻO kekahi o kēia mau hana e pili ana i ka hāʻawi ʻana i ka wahie a me ka oxidant i loko o nā cell, ka hoʻokaʻawale ʻana of nā pūnaewele likeʻole, ka hōʻiliʻili o ke au uila i hanaʻia, ka hoʻokuʻuʻana i ka wai mai kēlā me kēia pūnaewele, ka hoʻohaʻahaʻaʻana i nā kinoea a me ka hoʻomahaʻana o nā pūnaewele. Loaʻa i nā papa bipolar nā ala e hiki ai ke hele i nā mea hoʻoheheʻe (ka wahie a me ka oxidant) ma kēlā me kēia ʻaoʻao. Hoʻokumu lākou i nā ʻāpana anode a me nā cathode ma nā ʻaoʻao ʻē aʻe o ka pā bipolar. ʻOkoʻa paha ka hoʻolālā ʻana o nā kahawai kahe; hiki ke laina laina, wili, like.
ʻO VET ka pā bipolarmanufacturer i specializes i kiʻekiʻe hana maʻamau wahie cell nā mea nonā mea hana huahana, nā mea noiʻi a me nā mea hoʻonaʻauao a puni ka honua.Ua hoʻomohala mākou i nā papa graphite bipolar kumu kūʻai noHuina wahie(PEMFC) ʻo ia nā papa bipolar holomua me ka conductivity uila kiʻekiʻe a me ka ikaika mechanical maikaʻi. ʻO nā papa bipolar e ʻae i nā pūnaewele wahie e hana i nā wela kiʻekiʻe a loaʻa iā ia ka maikaʻi o ka uila a me ka wela.
