Ngokuchasene notshintsho olukhawulezayo lwamandla ehlabathi jikelele, iiseli ze-hydrogen fuel, njengomthwali obalulekileyo wamandla acocekileyo, zizisa amathuba ophuhliso angazange abonwe ngaphambili. I-membrane electrode assembly (MEA), njengenxalenye ephambili yeseli yefuel, ichaphazela ngokuthe ngqo ukusebenza kakuhle kunye nobomi benkqubo yonke yeseli. Phakathi kwezi, inkqubo yokulungiselela iphepha lekhabhoni le-gas diffusion layer (GDL), ingakumbi inkqubo yokulungisa kunye nokubumba, imisela ngokuthe ngqo isakhiwo se-porosity, i-conductivity, kunye namandla oomatshini e-GDL.
Amanqaku amane eNtlungu kunye neZisombululo kwiMveliso yePhepha leKhabhoni leGDL
Kubavelisi bephepha lekhabhoni le-GDL leeseli ze-hydrogen fuel, isitshixo sokuphumelela kwimarike sixhomekeke ekubeni bangakwazi na ukuvelisa iphepha lekhabhoni elisebenza kakuhle elinokuhambelana okuhle ngendlela ezinzileyo, esebenzayo, nengabizi kakhulu. Izixhobo zemveli zokuvelisa (ezifana noomatshini bokushicilela abathe tyaba kunye noomatshini bokushicilela abaqengqelekayo) zibeka imiqobo emininzi kwindlela eya kwimveliso enkulu.
Ingongoma yentlungu 1: Ukuhambelana okungalunganga kwemveliso, izinga eliphantsi lemveliso, kunye nobunzima bokuhanjiswa ngobuninzi
Ingxaki Yendabuko: Iipress zemveli ezisicaba zichaphazeleka kukuchaneka kokucubungula kweeplate zepress ezishushu kunye nokuguquguquka kobushushu beeplate emva kokufudumeza, okubangela ukuphambuka okuphezulu kubukhulu obufanayo bephepha lekhabhoni elicociweyo. Ukongeza, indlela yokucinezela eqhubekayo ivumela kuphela ukuveliswa kwamaphepha obungakanani obuthile, okwenza kube nzima ukubonelela abathengi ngeerolls zobukhulu obahlukeneyo. Ukucinezela kwendabuko kweroll kusebenzisa uxinzelelo ngokunxibelelana komgca, uxinzelelo luncipha ukusuka embindini weerollers ukuya eziphelweni, okubangela ukuba iphepha lekhabhoni libe qinile embindini kwaye likhululeke emaphethelweni. Oku kukhokelela ngokuthe ngqo kubukhulu obungalinganiyo kunye nokusasazwa kweepore okungahambelaniyo. Nokuba ngaphakathi kwebhetshi enye, okanye kwiphepha elifanayo lephepha lekhabhoni, ukusebenza kunokutshintshatshintsha, kunye neziphumo ezijikeleze malunga ne-85% kwixesha elide, nto leyo ebeka umngcipheko omkhulu wokuhanjiswa kweeodolo ezinkulu.
Isisombululo soxinzelelo lwe-Mingke isostatic: Itekhnoloji ye-isostatic ifezekisa uxinzelelo olufanayo 'lomphezulu' olusekelwe kumthetho kaPascal we-fluid mechanics.

- IxabisoUkuxuba: Isiphumo esiqhubekayo sesikali semveliso kunciphisa kakhulu ukwehla kwexabiso, amandla, kunye neendleko zabasebenzi ngemitha yesikwere.Imilinganiselo inayoumbonisonukuba iindleko zemveliso iyonke zingancitshiswa ngama-30%.
- Ukonga Abasebenzi: Inqanaba eliphezulu lokusebenza ngokuzenzekelayo livumela ukwehla kwama-67% kubasebenzi ngeshifti nganye.
Inqaku leNtlungu 3: Ithuba lenkqubo emxinwa, iindleko eziphezulu zokulungisa iimpazamo kunye novavanyo, kunye nokuvelisa izinto ezintsha okulinganiselweyo
Ingxaki Yendabuko: Ukusebenza kwephepha lekhabhoni le-GDL kubuthathaka kakhulu kubushushu kunye neejika zoxinzelelo. Izixhobo zemveli azikwazi ukulawula ubushushu ngokuchanekileyo kwaye zinejika elinye loxinzelelo, okwenza kube nzima ukuphinda ngokuchanekileyo inkqubo efanelekileyo yelebhu. Ngaba ufuna ukuzama ifomula entsha okanye isakhiwo esitsha? Umjikelo wokulungisa iimpazamo mde, izinga leziphene liphezulu, kwaye iindleko zovavanyo kunye neempazamo ziyoyikisa.
Isisombululo soxinzelelo olungaguqukiyo seMingke: Sibonelela ngeqonga lenkqubo eliguquguqukayo kakhulu nelilawuleka ngokuchanekileyo.
Iziphumo zeSisombululo:
- Ulawulo lobushushu oluchanekileyo: Ulawulo lobushushu oluzimeleyo oluneendawo ezininzi ngokuchanekileyo ukuya kuthi ga kwi-±0.5℃, ukuqinisekisa ukuphiliswa kwe-resin okugqibeleleyo.
- Uxinzelelo Oluhlengahlengiswayo: Uxinzelelo lunokubekwa ngokuchanekileyo kwaye lugcinwe ngaphakathi koluhlu lwebha ye-0-12 ukuze lufane ngokupheleleyo.
- InkquboImveliso: Nje ukuba iiparameter ezifanelekileyo zifunyenwe, zinoku "tshixwa" ngokucofa kube kanye kwinkqubo, zifezekise ukuphinda-phinda kwenkqubo nge-100% kwaye ziqinisekise ukusebenza okuzinzileyo kwemveliso.
- Uphando noPhuhliso oluQinisekisayo: UNanjing Mingke okwangoku unezifundo ezimbinii-ouble-oomatshini bovavanyo lwe-belt isostatic press, ababonelela ngeqonga lovavanyo elithembekileyo nelikumgangatho wemveliso lophando nophuhliso lwezixhobo ezintsha kunye nezakhiwo ezintsha, benciphisa kakhulu imiqobo kunye nemingcipheko yokuvelisa izinto ezintsha. Kwangaxeshanye, kwiinkampani ezintsha ezinemali encinci yokuqala kunye nobunzima bokuthenga izixhobo, iinkonzo zokuvelisa iikhontrakthi ezincinci eziqala kwiveki enye ukuya kwinyanga enye zinokunikezelwa ukuphucula amandla okuhambisa imveliso yekhabhoni, ukunceda amashishini aqhube imveliso yokuqala yovavanyo, ukunciphisa utyalo-mali olukhulu lwezixhobo, kunyeukunciphisaiingozi.
Inqaku leNhlungu 4:Intsalela yeglue yokunyibilikisa i-resin ye-phenolic, ukulahleka okukhulu kwephepha lokukhulula okanye izinto ezincedisayo ze-agent yokukhululas.
Ingxaki Yendabuko: Emva kokunyanga i-phenolic resin, kunzima ukwahlula kwipleyiti yokucinezela okanye ibhanti yentsimbi. Iinkampani zemveli zihlala zisebenzisa ii-release agents okanye iphepha lokukhulula ukufezekisa inkqubo yokususa, kodwa ii-release agents ezikumgangatho ophezulu okanye amaphepha okukhulula abiza kakhulu ukuwathenga, kwaye ukusetyenziswa okuphezulu ngexesha lenkqubo yokuvelisa kunyusa iindleko zokuvelisa iphepha lekhabhoni, nto leyo engayi kunceda ekufikeleleni kumaxabiso emveliso akhuphisanayo kwimarike.
Isisombululo seMingke Isostatic: I-Mingke's double steel belt isostatic press ivumela abathengi ukuba bakhethe ii-chrome-plated chrome-plated steel belts.
Isiphumo Sesisombululo: Ngovavanyo lwangaphakathi olwenziwe kwiMingke Factory kusetyenziswa iibhanti zentsimbi ezifakwe ichrome kwiphepha lekhabhoni elicocayo, kufunyenwe ukuba xa kuthelekiswa neebhanti zentsimbi eziprintiweyo zendabuko, iibhanti zentsimbi ezifakwe ichrome zibonelela ngokusebenza okungcono kokulungisa nokukhulula i-resin. Intsalela yeglue engaphezulu kulula ukuyisusa, kwaye xa isetyenziswa ngebrashi yokucoca ehambayo, iglu eseleyo kumphezulu webhanti yentsimbi inokususwa ngokulula, inceda abathengi ukunciphisa iindleko kwiiarhente zokukhulula kunye nephepha lokukhulula. Umaleko wechrome kumphezulu webhanti yentsimbi uphucula kakhulu ubulukhuni kunye nokumelana nokuguguleka kwebhanti. Ukongeza, ifilimu ye-oxide exineneyo eyenziwe ngumaleko wechrome kumphezulu webhanti yentsimbi ithintela ngempumelelo ukuguguleka kweoksijini, amanzi, kunye nezinye izinto ezibolayo, ngaloo ndlela yandisa ubomi benkonzo yebhanti yentsimbi.
