Izinto ze-graphite ziwuhlobo lwe-bipolar plate olwakhiwe futhi lwasetshenziswa ngaphambilini. Ama-bipolar plate endabuko asebenzisa kakhulu ama-graphite plate angenazo izimbobo, futhi imifantu icutshungulwa ngomshini wokugaya. I-graphite bipolar plate ine-coefficient yokukhulisa ukushisa ephansi, i-thermal conductivity enhle, izakhiwo zamakhemikhali ezizinzile, ukumelana okuhle nokugqwala kanye ne-electric conductivity enamandla. Kodwa-ke, ukuphuka kwe-graphite kubangela ubunzima bokucubungula, futhi ngesikhathi esifanayo kuvimbela ukwehla kobukhulu be-graphite plate, futhi kulula ukukhiqiza ama-pores ngesikhathi senqubo yokukhiqiza, ukuze uphethiloli kanye ne-oxidant kungene komunye nomunye, ngakho-ke ezinye izinto kumele zengezwe ukuthuthukisa ukusebenza kwebhethri.
Sithuthukise amapuleti e-graphite bipolar angabizi kakhulu e-PEMFC adinga ukusetshenziswa kwamapuleti e-bipolar athuthukile anokuqhutshwa kukagesi okuphezulu kanye namandla amahle okusebenza. Amapuleti ethu e-bipolar avumela amaseli kaphethiloli ukuthi asebenze emazingeni okushisa aphezulu futhi abe nokuqhutshwa kukagesi nokushisa okuhle kakhulu.
Sinikeza izinto ze-graphite nge-resin efakwe emanzini ukuze kufezwe ukungenwa yigesi kanye namandla aphezulu. Kodwa izinto zigcina izakhiwo ezinhle ze-graphite maqondana nokuqhuba kukagesi okuphezulu kanye nokuqhuba okuphezulu kokushisa.
Singasebenzisa amapuleti e-bipolar kuzo zombili izinhlangothi ngamasimu okugeleza, noma uhlangothi olulodwa lomshini noma sinikeze amapuleti angenalutho angakasetshenziswa. Wonke amapuleti e-graphite angasebenza ngomshini ngokwedizayini yakho eningiliziwe.
Idatha Yezinto Ze-Graphite Bipolar Plates:
| Izinto | Ubuningi obukhulu | Ukugoba Amandla | Amandla Okucindezela | Ukumelana Okuqondile | Vula i-Porosity |
| I-GRI-1 | 1.9 g/cc min | 45 Mpa min | 90 Mpa min | Ubuningi be-10.0 micro ohm.m | Ubuningi obungu-5% |
| Amazinga engeziwe ezinto ze-graphite ayatholakala ukuze ukhethe ngokwesicelo esithile. | |||||
