Amapuleti e-Bipolar

Amapuleti e-Bipolarzenziwe nge-graphite noma insimbi; basakaza ngokulinganayo amafutha kanyei-oxidant kumaseli e-fuel cell. Baphinde baqoqe amandla kagesi akhiqizwayo kumatheminali okukhiphayo.

Ku-fuel cell cell eyodwa, ayikho i-bipolar plate; nokho, kukhona ipuleti elilodwa emaceleni elihlinzekaukuhamba kwama-electron. Kumaseli amafutha anamaseli angaphezu kweyodwa, kukhona okungenani ipuleti elilodwa le-bipolar (ukulawula ukugeleza kukhona nhlangothi zombili zepuleti). Amapuleti e-Bipolar ahlinzeka ngemisebenzi eminingana ku-fuel cell.

Eminye yale misebenzi ihlanganisa ukusatshalaliswa kwamafutha kanye ne-oxidant ngaphakathi kwamaseli, ukuhlukaniswa kwamaseli ahlukene, ukuqoqwa kwamaseli.amandla kagesikukhiqizwa, ukuphuma kwamanzi esitokisini ngasinye, ukucwiliswa kwamagesi nokupholisa kwamaseli. Amapuleti e-bipolar nawo aneziteshi ezivumela ukudlula kwezinto ezisabelayo (uphethiloli ne-oxidant) ohlangothini ngalunye. BakhaIzingxenye ze-anode ne-cathodeezinhlangothini eziphambene zepuleti le-bipolar. Ukuklanywa kwamashaneli okugeleza kungase kuhluke; zingase zibe ngomugqa, zigoqeke, zihambisane, zibe yikama noma zibe nezikhala ezilinganayo njengoba kukhonjisiwe esithombeni esingezansi.

Izinhlobo ezahlukene ze-bipolar plate [COL 08]. a) Amashaneli okugeleza ahlanganisiwe; b) amashaneli amaningi okugeleza kwamakhoyili; c) imigudu yokugeleza ehambisanayo; d) amashaneli okugeleza ahlanganisiwe

Izinto ezisetshenziswayo zikhethwa ngokusekelweukuhambisana kwamakhemikhali, ukumelana nokugqwala, izindleko,conductivity kagesi, ikhono lokusabalalisa igesi, ukungakwazi ukungena emanzini, ukukhululeka komshini, amandla omshini kanye nokuhamba kwawo okushisayo.
