Purati yebipolar, inozivikanwawo sepurati yekuunganidza, ndeimwe yezvinhu zvakakosha zvefuel cell. Ine mabasa anotevera uye hunhu: kupatsanura mafuta neoxidizer, kudzivirira kupinda kwegasi; Kuunganidza nekufambisa magetsi, conductivity yakakwira; Nzira yekuyerera yakagadzirwa uye yakagadziriswa inogona kuparadzira gasi zvakaenzana kune reaction layer ye electrode ye electrode reaction. Kune maitiro akati wandei ekutenderera ema graphite bipolar plates.
1, nzira yekumonera ndiro ine machira akawanda:
Maitiro ekushanda kwemuchina wekumonera unoenderera mberi une ma layer akawanda: veneer inotorwa kubva patsvimbo yekumonera yeveneer, uye chinonamira kumativi ese evhu kuburikidza nebinder coating roller, uye winding roll neveneer zvinosanganiswa kuti zvive ndiro ine ukobvu hutatu, uye mukaha uri pakati pema rollers unomonerwa kuita ukobvu hwakati. Wobva waisa mu heater kuti ipise uye iome. Kuburikidza nekudzora ukobvu, monerera, gadzirisa ukobvu kuti husvike saizi yakatarwa, wozotumira kuchishandiso chekugocha kuti chigocherwe. Kana binder yaiswa carbon, inozopedzisira yadzvanywa kuita chimiro ne pressure roller.
Uchishandisa nzira yekumonera inoenderera mberi, girafu yegirafu inochinjika ine ukobvu hwe0.6-2mm inogona kudzvanywa, izvo zviri nani pane muchina wekumonera une layer imwe chete, asi nekuda kweukobvu hwepuratifomu iyi, zvichaunzawo zvikanganiso zvekubvisa puratifomu, izvo zvichaunza matambudziko pakushandisa. Chikonzero ndechekuti gasi rinopfungaira rinoramba riri pakati pe layer panguva yekudzvanya, izvo zvinodzivirira kubatana kwepedyo pakati pe layer. Nzira yekuvandudza ndeyekugadzirisa dambudziko regasi rinobuda mumhepo panguva yekudzvanya.
Kutenderedza ndiro imwe chete, kunyangwe ndiro yekumanikidza iri yakatsetseka, asi isiri hombe zvakanyanya. Kana kuumbwa kwayo kwakanyanya, kufanana kwayo uye huwandu hwayo zvakaoma kuva nechokwadi. Kuti pagadzirwe maplate akakora, mabhodhi akawanda anoiswa pamusoro uye anodzvanywa mumabhodhi akawanda. Chinosungirirwa chinowedzerwa pakati pezvikamu zviviri zvega zvega uye chobva chatenderedzwa. Mushure mekuumbwa, chinopiswa kuti chisimbiswe uye chiome. Nzira yekutenderedza ndiro yakawanda inoitirwa pamuchina unotenderedza unoenderera mberi une maplate akawanda.
2, ndiro imwe chete inotenderera nzira inoenderera mberi:
Maumbirwo eroller ane: (1) hopper yegrafiti yehonye; (2) Mudziyo wekudyisa wevibration; (3) Bhandi reConveyor; (4) Maroller mana ekumanikidza; (5) Peya yemaheater; (6) roller yekudzora ukobvu hwepepa; Maroller ekuisa embossing kana patterning; (8) uye roller; (9) Banga rekucheka; (10) Roller yechigadzirwa chapera.
Nzira iyi yekumonera inogona kudzvanya graphite inochinjika kuita mapepa pasina chinosunga, uye maitiro ese anoitirwa pamidziyo yakakosha ine maroller roller.
Maitiro ekushanda: graphite yakachena kwazvo inopinda mumudziyo wekudyisa kubva muhopper yowira pabhandi rekufambisa. Mushure mekutenderedza roller yekumanikidza, ichigadzira ukobvu hwakati hwechikamu chezvinhu. Mudziyo wekudziya unogadzira kupisa kwakanyanya kuti ubvise gasi rakasara muchikamu chezvinhu uye kuwedzera graphite isina kuwedzerwa kekupedzisira. Zvadaro chinhu chakatanga kugadzirwa chinopinzwa muroller inodzora saizi yeukobvu uye chinodzvanywa zvakare zvichienderana nehukuru hwakatarwa kuitira kuti pave neplate yakati sandara ine ukobvu hwakafanana uye density yakati. Pakupedzisira, mushure mekucheka nemuchina wekucheka, peta bharero rapera.
Zviri pamusoro apa ndezvekuumbwa kwegrafiti bipolar plate, ndinotarisira kukubatsira. Pamusoro pezvo, zvinhu zvine kabhoni zvinosanganisira graphite, zvinhu zvakaumbwa nekabhoni uye graphite yakawedzerwa (inochinjika). Maplate ebipolar akajairika anogadzirwa negrafiti yakakora uye anogadzirwa mumigero yekuyerera kwegasi. Grafiti bipolar plate ine hunhu hwemakemikari hwakagadzikana uye inodzivirira kubatwa neMEA.
