Abun graphite abu ne na farantin bipolar wanda aka haɓaka kuma aka yi amfani dashi a baya. Farantin bipolar na gargajiya galibi suna amfani da faranti na graphite marasa porous, kuma ana sarrafa ramukan ta hanyar injina. A graphite bipolar farantin yana da low thermal fadada coefficient, mai kyau thermal conductivity, barga sinadaran Properties, mai kyau lalata juriya da kuma karfi lantarki watsin. Duk da haka, brittleness na graphite yana haifar da matsalolin aiki, kuma a lokaci guda yana ƙuntata rage kauri na farantin graphite, kuma yana da sauƙi don samar da pores yayin aikin masana'antu, ta yadda man fetur da oxidant zasu iya shiga juna. don haka dole ne a ƙara wasu abubuwa don inganta aikin baturi.
Mun haɓaka faranti mai siffa mai ɗorewa mai tsada don PEMFC wanda ke buƙatar amfani da faranti na ci gaba tare da babban ƙarfin lantarki da ingantaccen ƙarfin injina. Farantin mu na bipolar suna ba da damar ƙwayoyin mai suyi aiki a yanayin zafi mai girma kuma suna da kyakkyawan ƙarfin lantarki da yanayin zafi.
Muna ba da kayan graphite tare da guduro mai lalacewa don cimma ƙarancin gas da ƙarfi mai ƙarfi. Amma kayan yana riƙe da kyawawan kaddarorin graphite dangane da haɓakar wutar lantarki mai ƙarfi da haɓakar thermal.
Za mu iya injin faranti biyu na ɓangarorin biyu tare da filayen kwarara, ko injin gefe guda ko kuma samar da faranti marasa na'ura kuma. Za a iya sarrafa duk faranti na graphite bisa ga cikakken ƙirar ku.
Takardar bayanan Material Plates Bipolar Graphite:
Kayan abu | Yawan yawa | Mai sassauƙa Ƙarfi | Ƙarfin Ƙarfi | Takamaiman Juriya | Bude Porosity |
GRI-1 | 1.9g/cc min | 45 Mpa min | 90 Mpa min | 10.0 micro ohm.m max | 5% max |
Akwai ƙarin maki na kayan graphite don zaɓar bisa ga takamaiman aikace-aikacen. |
