- Lipoleiti tsa graphite bipolar ke likarolo tsa mantlha tsa li-fuel cell stacks, tse ikarabellang ho feta 60% ea molumo oa stack, ho feta 80% ea boima, le 30-40% ea litšenyehelo. Hase feela poleiti ea karohano ea sele ea betri, empa hape le poleiti ea tšimo ea phallo le poleiti ea mokelli oa hona joale, e ikarabellang bakeng sa mesebetsi e mengata e kang ho aba likhase tse arabelang, ho bokella conduction hona joale, mocheso le drainage, le tšehetso ea mechine.
- Ke hobane'ng ha u sebelisa graphite ho e-na le tšepe? Tikoloho e sebetsang ea lisele tsa mafura e ikhethile - ho na le acidic electrolyte (proton exchange membranes), mongobo o phahameng, le maemo a feto-fetohang a redox ka hare. Metal bipolar plates e na le monyetla oa ho bola tikolohong ena, 'me lihlahisoa tse senyang li ka silafatsa ts'oaetso, e leng se lebisang ho fokotseha ha ts'ebetso ea betri. Lipoleiti tsa graphite bipolar li na le lik'hemik'hale tse matla tse sa sebetseng hantle, li hanyetsa ho bola ho matla ho feta litšepe, li-conductivity tse ntle le letsoalo le tlase, e leng se etsang hore e be tsona khetho e ka sehloohong bakeng sa lisele tsa mafura tsa khoebo hajoale.
- Lipoleiti tsa graphite bipolar li arotsoe ka mekhahlelo e meraro ho latela mekhoa ea tlhahiso:
① Lipoleiti tse hloekileng tsa graphite bipolar - tse entsoeng ka-ka graphite e hloekileng ka liteishene tse nepahetseng tsa ho sila, tse sebetsang hantle empa li bitsa chelete e ngata le nako e telele ea ho sebetsa;
② Letlapa le atolositsoeng la graphite bipolar - le entsoeng ka ho hatakela poleiti ea graphite e feto-fetohang, ka theko e tlase empa matla a sebetsang a fokola;
③ Letlapa le kopaneng la bipolar - phofo ea graphite+resin e tsoakiloeng, litšenyehelo tse leka-lekaneng le ts'ebetso, hajoale ke eona tsela e tsebahalang haholo.
- Ka ho qhoma ha indasteri ea matla a hydrogen, 'maraka oa graphite bipolar plate o lebelletsoe ho hola ho tloha ho li-yuan tse ka bang limilione tse likete tse 5 ka 2025 ho ea ho li-yuan tse limilione tse likete tse 30 ka 2030, ka sekhahla sa kholo ea selemo le selemo se fetang 40%. Ena ke pina ea kholo e phahameng ka bonnete.
