Kufotokozera kwamafuta cell Graphite bipolar mbale:
Ntchito ya mbale ya bipolar (yomwe imadziwikanso kuti diaphragm) ndiyo kupereka njira yoyendetsera mpweya, kuteteza kugwirizana pakati pa haidrojeni ndi mpweya mu chipinda cha mpweya wa batri, ndikukhazikitsa njira yamakono pakati pa mitengo ya Yin ndi Yang motsatizana. Pamaziko a kukhalabe ndi mphamvu zamakina komanso kukana kwa mpweya wabwino, makulidwe a mbale ya bipolar iyenera kukhala yopyapyala momwe mungathere kuti muchepetse kukana kwa conduction pakalipano komanso kutentha.
Zida za carbonaceous. Zipangizo zokhala ndi mpweya zimaphatikizapo graphite, zida za kaboni zoumbidwa ndi graphite yowonjezeredwa (yosinthika). Mbale yachikhalidwe ya bipolar imatenga graphite wandiweyani ndipo imapangidwa kukhala tchanelo cha gasi · Mbale ya graphite bipolar ili ndi mankhwala okhazikika komanso osalumikizana pang'ono ndi mea.
Ma mbale a bipolar amafunikira chithandizo choyenera chapamwamba. Pambuyo kupaka faifi pa mbali ya anode ya mbale bipolar, madutsidwe ndi zabwino, ndipo si kophweka kuti nyonyowetsa ndi electrolyte, amene angapewe kutaya electrolyte. Kulumikizana kosavuta pakati pa electrolyte diaphragm ndi mbale ya bipolar kunja kwa malo ogwira ntchito a elekitirodi amatha kuteteza mpweya kuti usatuluke, chomwe chimatchedwa "chisindikizo chonyowa". Kuti muchepetse dzimbiri za carbonate yosungunuka pazitsulo zosapanga dzimbiri pamalo a "nyowa chisindikizo", chimango cha mbale ya bipolar chiyenera "kuwalitsidwa" kuti chitetezedwe.

Mayeso oletsa kuphulika kwa mbale zomatira (njira yochokera ku kampani yaku America yamafuta a bipolar plate)
Chida chapadera chimatseka mbali zinayi za mbale yomatira ndi wrench ya torque ya 13N.M, ndikukakamiza chipinda chozizira. Chomata chomata sichidzatsegulidwa ndi kutayikira pamene mphamvu ya mpweya ndi ≥4.5KG (0.45MPA)
Kuyeza kwa mpweya wa mbale zomatira
Pansi pa kukakamiza chipinda chozizira ndi 1KG(0.1MPA), palibe kutayikira muchipinda cha haidrojeni, chipinda cha oxygen ndi chipinda chakunja.
Muyezo wotsutsana nawo
Kukana kulumikizana ndi mfundo imodzi: ＜9mΩ.cm2 Avereji yokana kukhudzana:＜6mΩ.cm2
Zofunika Kusamala:
Osayika zida zakuthwa m'bokosi potsegula, zomwe zingayambitse kuwonongeka kwa chinthucho.
Mukatulutsa chinthucho, tsitsani pepala lolemba mofatsa mpaka ngodya ya chinthucho ikwezedwa pang'ono,
kenako tulutsani mankhwala onse
Ndi bwino kuvala magolovesi yosalala disposable mu ndondomeko kutenga mankhwala.
Iyenera kuchitidwa mopepuka kuti isawononge kuwonongeka kwa mankhwala.

Quick Service
Potengera zomwe mwayitanitsa, gulu lathu la akatswiri ogulitsa litha kuyankha zomwe mwafunsa mkati mwa mphindi 50-100 panthawi yogwira ntchito komanso mkati mwa maola 12 panthawi yotseka. Kuyankha mwachangu komanso mwaukadaulo kukuthandizani kupambana kasitomala wanu ndi njira yabwino kwambiri.
Pochita madongosolo, gulu lathu la akatswiri amajambula zithunzi masiku 3 mpaka 5 aliwonse kuti mumve zambiri zazomwe mwapanga ndikukupatsani zikalata mkati mwa maola 36 kuti zisinthire momwe ntchito yotumizira ikuyendera. Timalabadira kwambiri pambuyo-kugulitsa utumiki.
Pagawo logulitsa pambuyo pake, gulu lathu lautumiki nthawi zonse limalumikizana nanu ndipo nthawi zonse limakudalirani. Katswiri wathu atagulitsa ntchito amaphatikizanso mainjiniya athu kuti akuthandizeni kuthana ndi mavuto patsamba. Chitsimikizo chathu ndi miyezi 12 mutabereka.
