Mafuta a Cell Graphite Plate, mbale ya Carbon bipolar

Zinthu za graphite ndi mbale ya bipolar yomwe idapangidwa ndikugwiritsidwa ntchito kale. Ma mbale a chikhalidwe cha bipolar makamaka amagwiritsa ntchito mbale za graphite zopanda porous, ndipo ma grooves amakonzedwa ndi makina. Mbalame ya graphite bipolar ili ndi mphamvu yowonjezera yowonjezera kutentha, kuyendetsa bwino kwamafuta, kukhazikika kwa mankhwala, kukana kwa dzimbiri komanso mphamvu zamagetsi zamagetsi. Komabe, brittleness ya graphite imayambitsa mavuto pokonza, ndipo nthawi yomweyo imaletsa kuchepetsa makulidwe a mbale ya graphite, ndipo n'zosavuta kupanga pores panthawi yopanga, kotero kuti mafuta ndi okosijeni amatha kudutsana wina ndi mzake. kotero zinthu zina ziyenera kuwonjezeredwa kuti ziwongolere magwiridwe antchito a batri.

Tapanga mbale zotsika mtengo za graphite bipolar za PEMFC zomwe zimafuna kugwiritsa ntchito mbale zapamwamba za bipolar zokhala ndi magetsi okwera kwambiri komanso mphamvu zamakanika. Ma mbale athu a bipolar amalola kuti ma cell amafuta azigwira ntchito pakatentha kwambiri komanso amakhala ndi mphamvu yabwino kwambiri yamagetsi ndi matenthedwe.

Timapereka zinthu za graphite zokhala ndi utomoni wolowetsedwa kuti tikwaniritse kusakwanira kwa mpweya komanso mphamvu yayikulu. Koma zakuthupi amakhalabe yabwino zimatha graphite mawu a mkulu madutsidwe magetsi ndi mkulu matenthedwe madutsidwe.

Titha kusindikiza mbale za bipolar mbali zonse ziwiri ndi minda yoyenda, kapena makina mbali imodzi kapena kuperekanso mbale zopanda kanthu. Ma mbale onse a graphite amatha kupangidwa molingana ndi kapangidwe kanu mwatsatanetsatane.
