electrolytic graphite poleiti Bipolar Plate bakeng sa Hydrogen Fuel Cell

Hydrogen fuel cell stack e entsoe ka lisele tse ngata tsa mafura tse pakiloeng ka letoto.The bipolar poleiti le lera electrode MEA li overlapped alternately, le litiiso ba embedded pakeng tsa mong le e mong monoma.Ka mor'a ho hatelloa ke lipoleiti tse ka pele le tse ka morao, li tlamisoa le ho fasoa ka li-screw ho etsa stack ea hydrogen fuel cell.

Letlapa la bipolar le membrane electrode MEA li kopantsoe ka tsela e fapaneng, 'me litiiso li kentsoe pakeng tsa monoma ka mong.Ka mor'a ho hatelloa ke lipoleiti tse ka pele le tse ka morao, li tlamisoa le ho fasoa ka li-screw ho etsa "hydrogen fuel cell stack".bipolar plate e entsoeng ka graphite ea maiketsetso.Letlapa la bipolar le entsoeng ka mofuta ona oa thepa le na le conductivity e ntle le ho hanyetsa kutu.Leha ho le joalo, ka lebaka la litlhoko tsa ho tiisa moea oa poleiti ea bipolar, ts'ebetso ea tlhahiso e hloka mekhoa e mengata ea tlhahiso e kang resin impregnation, carbonization, graphitization le ts'ebetso e latelang ea tšimo ea phallo, kahoo mokhoa oa ho etsa lihlahisoa o rarahane 'me litšenyehelo li phahame haholo. fetoha ntho ea bohlokoa e thibelang tšebeliso ea mafura cell.
