Bipolar farantin ne core bangaren na reactor, wanda yana da babban tasiri a kan aiki da kuma kudin na reactor. A halin yanzu, farantin bipolar an raba shi zuwa farantin graphite, farantin da aka haɗa da farantin ƙarfe bisa ga kayan.
Bipolar farantin yana daya daga cikin ainihin sassan PEMFC, babban aikinsa shi ne jigilar iskar gas ta filin da ke gudana, tattara da gudanar da halin yanzu, zafi da ruwa da aka haifar ta hanyar amsawa. Dangane da nau'in kayan, nauyin tarin PEMFC shine kusan 60% zuwa 80% kuma farashin shine kusan 30%. Dangane da buƙatun aiki na farantin bipolar, da kuma la'akari da yanayin yanayin amsawar electrochemical na PEMFC, ana buƙatar farantin bipolar don samun manyan buƙatu don haɓakar lantarki, ƙarancin iska, kaddarorin injin, juriya na lalata, da sauransu.
Farantin biyu bisa ga kayan, galibi zuwa kashi uku na farantin graphite, farantin mai haɗawa, farantin ƙarfe, farantin graphite sau biyu shine mafi yawan amfani da farantin gida na PEMFC na gida a halin yanzu, ƙarancin wutar lantarki, ƙarancin thermal, kwanciyar hankali mai kyau da juriya lalata da sauran ayyukan. amma in mun gwada da matalauta inji Properties, gaggautsa, machining matsalolin kai ga high cost matsaloli placing da yawa masana'antun.
Graphitefarantin bipolargabatarwa:
Bipolar faranti da aka yi da graphite suna da kyakykyawan halayen wutar lantarki, daɗaɗɗen zafin jiki da juriya na lalata, kuma su ne faranti da aka fi amfani da su a cikin PEEMFCS. Duk da haka, da disadvantages ne kuma mafi bayyananne: da graphitization zafin jiki na graphite farantin yawanci ya fi 2500 ℃, wanda bukatar da za a za'ayi bisa ga m dumama hanya, da kuma lokaci ne mai tsawo; Tsarin injin yana jinkirin, sake zagayowar yana da tsayi, kuma daidaitaccen injin yana da girma, yana haifar da tsadar farantin graphite; Graphite yana da rauni, farantin da aka gama yana buƙatar kulawa da hankali, haɗuwa yana da wahala; Graphite yana da ƙura, don haka faranti suna buƙatar zama 'yan milimita masu kauri don ƙyale iskar gas su rabu, yana haifar da ƙananan ƙarancin kayan da kanta, amma samfurin da aka gama mafi nauyi.
