- Iipleyiti zegraphite zebipolar zezona zixhobo zingundoqo ze-hydrogen fuel cell, ezibalelwa ngaphezulu kwe-60% ye-stack volume, ngaphezulu kwe-80% yobunzima, kunye ne-30-40% yeendleko. Akunjalo kuphela i-plate ye-partition plate ye-cell cell, kodwa kunye ne-flow field plate kunye ne-collector plate yangoku, ejongene nemisebenzi emininzi efana nokusabalalisa i-gesi reaction, ukuqokelela i-conduction current, ukushisa kunye nokukhutshwa kwamanzi, kunye nenkxaso yomatshini.
- Kutheni usebenzisa igraphite endaweni yesinyithi? Indawo yokusebenza yeeseli zepetroli yohlukile - kukho i-electrolyte eneasidi (iproton exchange membranes), ukufuma okuphezulu, kunye ne-redox atmospheres etshintshanayo ngaphakathi. Iipleyiti ze-Metal bipolar zivame ukubola kule ndawo, kwaye iimveliso zokubola zingangcolisa i-catalyst, ekhokelela ekwehleni kokusebenza kwebhetri. Iipleyiti zeGraphite bipolar zinamandla okungasebenzi kweekhemikhali, ukuxhathisa okuphezulu kakhulu kwintsimbi, ukuqhuba kakuhle, kunye noxinaniso oluphantsi, nto leyo ezenza zibe lolona khetho luphambili kwiiseli zamafutha ezorhwebo ngoku.
- Iipleyiti ze-bipolar zegraphite zohlulwe zibe ziindidi ezintathu ngokweenkqubo zokuvelisa:
① Iipleyiti zegraphite bipolar ezisulungekileyo - zenziwe ngegraphite ephezulu{1}}esulungekileyo ngokusebenzisa amajelo okusila achanekileyo, asebenza ngeyona ndlela ingcono kodwa ixabiso eliphezulu kunye nomjikelo wokusetyenzwa omde;
② Ipleyiti eyandisiweyo yegraphite bipolar - eyenziwe ngokugximfiza ipleyiti yegraphite eguquguqukayo, enexabiso eliphantsi kodwa amandla omatshini abuthathaka;
③ Ipleyiti edityanisiweyo ye-bipolar - umgubo wegraphite+intlaka exutyiweyo yokubumba, ukulinganisa iindleko kunye nokusebenza, ngoku yeyona ndlela iphambili.
- Ngokuqhambuka koshishino lwamandla e-hydrogen, imakethi ye-graphite bipolar plate kulindeleke ukuba ikhule ukusuka malunga neebhiliyoni ezi-5 zeeyuan ngo-2025 ukuya ngaphezulu kwe-30 yeebhiliyoni zeeyuan ngo-2030, kunye nesantya sokukhula sonyaka esingaphezulu kwama-40%. Lo ngumzila wokukhula okuphezulu ngokuqiniseka.
