Fuel Cell Grade Graphite Plate, Carbon bipolar plate

Lisebelisoa tsa graphite ke lisebelisoa tsa poleiti ea bipolar e ileng ea ntlafatsoa le ho sebelisoa pejana. Lipoleiti tsa setso tsa bipolar haholo-holo li sebelisa lipoleiti tsa graphite tse se nang porous, 'me li-grooves li sebetsoa ka machining. Letlapa la graphite bipolar le na le coefficient e tlase ea katoloso ea mocheso, conductivity e ntle ea mocheso, thepa e tsitsitseng ea lik'hemik'hale, e thibelang kutu e ntle le conductivity e matla ea motlakase. Leha ho le joalo, brittleness ea graphite e baka mathata a ho sebetsa, 'me ka nako e ts'oanang e thibela ho fokotseha ha botenya ba poleiti ea graphite,' me ho bonolo ho hlahisa li-pores nakong ea ts'ebetso ea tlhahiso, e le hore mafura le oxidant li ka phunyeletsana; kahoo lintho tse ling li tlameha ho eketsoa ho ntlafatsa ts'ebetso ea betri.

Re qapile lipoleiti tsa graphite bipolar tse sa sebetseng hantle bakeng sa PEMFC tse hlokang tšebeliso ea lipoleiti tse tsoetseng pele tse nang le motlakase o phahameng le matla a matle a mochini. Lipoleiti tsa rona tsa bipolar li lumella lisele tsa mafura hore li sebetse ka mocheso o phahameng 'me li na le motlakase o motle haholo le mocheso oa mocheso.

Re fana ka thepa ea graphite e nang le resin e kentsoeng e le hore re finyelle ho se khonehe ha khase le matla a phahameng. Empa thepa e boloka thepa e ntle ea graphite ho latela maemo a phahameng a motlakase le mocheso o phahameng oa mocheso.

Re ka kenya lipoleiti tsa bipolar mahlakoreng ka bobeli ka libaka tsa phallo, kapa mochini o lehlakoreng le le leng kapa ra fana ka lipoleiti tse se nang mochini tse se nang mochini. Lipoleiti tsohle tsa graphite li ka etsoa ho latela moralo oa hau o hlakileng.
