Kwicandelo lokwenziwa kweeseli ze-hydrogen fuel, i-Membrane Electrode Assembly (MEA) isebenza njengeyona nto iphambili yokuguqulwa kwamandla, imisela ngokuthe ngqo ukusebenza kwebhetri kunye nobomi bayo. Inyathelo lokuqala lemveliso ye-MEA ngokugqithiselwa kobushushu kukuxutywa kodaka—inyathelo elibalulekileyo elichaphazela umgangatho wokugqibela wemveliso. Le nkqubo ifuna ukuxutywa okuchanekileyo kwe-Pt-C catalysts, izinyibilikisi, kunye nezibophelelo ukwenza umxube ozinzileyo osasazwe ngokufanayo.
Umzabalazo wokuxuba wemveli ukulawula ngokuchanekileyo umlinganiselo wecandelo ngalinye kunye nelizwe losasazo, okukhokelela kwimiba efana nokungalinganiyo kokutyabeka kunye nokunciphisa umsebenzi we-catalytic kumanyathelo alandelayo. Ukusetyenziswa kweiimitha zoxinaniso olungaphakathi inika isisombululo sempumelelo, esenza ukuba kulawuleke ngokuthe ngqo ulungelelwaniso lwamacandelo kunye neziphumo zokusasazwa ngokujongwa kwexesha lokwenyani lotshintsho lwengxinano yodaka.
IQela le-Lonnmeter, umvelisi ophambili kunye nomboneleli weemitha zokuxinana okungaphakathi, unikezele amashumi eminyaka ukubonelela ngezisombululo zobungcali kubathengi kwihlabathi liphela. Ezi zisombululo zincede iifektri ezininzi zemizi-mveliso, amashishini ombane, kunye namashishini esinyithi anciphisa iindleko kunye nokuphucula ukusebenza kakuhle.
Indima ebalulekileyo yokuxuba i-Slurry
Ukusebenza kwe-hydrogen fuel cell MEAs kakhulu kuxhomekeke ekufaniseni kunye nokuzinza kwee-catalyst slurries. Ngokomzekelo, i-anode slurries idinga i-15% ye-Pt-C i-catalyst ihlakazwe ngokufanayo kwi-solvent edibeneyo ye-40% yamanzi e-deionized, i-40% ye-methanol, kunye ne-5% yesisombululo se-ionomer; i-cathode slurries ifuna umlinganiselo ophezulu we-catalyst (20%) kunye ne-binder (10%). Lo mlinganiselo uchanekileyo awuchaphazeli nje kuphela iipropathi ezibonakalayo ze-slurry kodwa uchaphazela ngokuthe ngqo ukuhanjiswa kweendawo ezisebenzayo ze-catalytic kunye neproton conductivity.
Ulawulo loxinano olungafanelekanga lunokubangela ukudityaniswa kwe-catalyst agglomeration okanye intlenga, okukhokelela kubunzima obungalinganiyo be-catalyst egqunyiweyo kunye nokusebenza kwebhetri kukonke. Umzekelo, ukuxinana okuphezulu kunokubonisa i-catalyst egqithisileyo okanye ukunyuka kwe-solvent, ukunyuka kwe-slurry viscosity kunye nokubangela "i-peel ye-orange" okanye "i-pinhole" iziphene ngexesha lokwaleka; Uxinzelelo olusezantsi lunokubonisa ukungonelanga kwe-catalyst, ukusilela ukubonelela ngeendawo zokusabela ezifanelekileyo kunye nokunciphisa ukusebenza kakuhle kwebhetri.
Unyino loLawulo lweSintu lokuNina koLudaka
Ukuxutywa kodaka lwe-catalyst kuxhomekeke kubunzima besandla kunye novavanyo olungaxhunyiwe kwi-intanethi kwiprayimari. Le ndlela isemva kwenkqubo yexesha lokwenyani kakhulu-ukufumana iziphumo zovavanyo kwisampulu kuhlala kuthatha imizuzu eyi-15 ukuya kwengama-30, ngelo xesha udaka lunokungena kwinkqubo elandelayo, nto leyo ekhokelela kwinkunkuma enkulu.
Imisebenzi yezandla iyasokola ukufumana i-nanoscale catalyst particle agglomeration. Ukongezelela, izinto ezifana nokutshintsha kweqondo lokushisa kunye nokunyuka kwe-solvent evaporation kubangela ukuguquguquka koxinzelelo oluguquguqukayo kwi-slurries, ezo iinkqubo zendabuko azikwazi ukuhlawulela ngexesha langempela, ngakumbi ukunyusa umngcipheko wokungazinzi komgangatho.
Umgaqo-siseko wokuSebenza kunye neeNgcebiso zobuGcisa
Ukujongana nale mingeni, iinjineli zeLonnmeter ziphuhlise iimitha zoxinaniso olungaphakathi olusekwe kumgaqo wamandla weCoriolis, olinganisa ukungcangcazela kwamanzi rhoqo ukuze kufumaneke idatha yoxinano lwexesha lokwenyani ngokuchanekileyo ukuya kuthi ga ku ±0.001 g/cm³. Ekuxutyweni kwe-slurry ye-hydrogen fuel cell, ezi zixhobo zokubeka iliso ezichanekileyo ziyakwazi ukufakwa kwindawo yokuphuma kwamatanki okuxuba okanye imibhobho yokujikeleza ngokuqhubekayo ukuqokelela idatha yobuninzi kunye neqondo lokushisa, kunye ne-algorithms yembuyekezo esusa impembelelo yobushushu ekuxininiseni.
Ngaphaya kweemitha zokuxinana kweCoriolis, iLonnmeter ikwaphuhlise ezinye iimitha zokuxinana kwe-inline ezifana nokulungisa iimitha zoxinaniso lwefolokhwe kunye nemitha yoxinano lwe-ultrasonic ukubonelela ngezinzwa ezikrelekrele zokuxinaniswa kweemeko zokusebenza ezahlukeneyo. Xa ufumanisa ukuba i-cathode slurry density idlula ixabiso elijoliswe kuyo, inkqubo ibala ngokuzenzekelayo ukuphambuka kwaye yongeza inani elifanelekileyo le-solvent ngokusebenzisa ipompo yokulinganisa; ukuba ingxinano iphantsi kakhulu, kongezwa utywala be-catalyst obusasazwe kwangaphambili. Olu lawulo luguqukayo alulungiseleli nje ukutenxa kwifomula kuphela kodwa luqikelela nemiba enokubakho ngohlalutyo lwembali lwedatha. Xa ukuguquguquka koxinano kudlula i-thresholds, inkqubo ibangela ii-alam ukukhuthaza ukusasazwa okungafaniyo okanye ukwahlukana kwesigaba, ukuthintela iingozi zebhetshi ngakumbi.
Iziphumo zokuBeka esweni koXinano oluqhubekayo
Uzinzo lweSeli yeFuel eyandisiweyo
Iimitha ze-Lonnmeter zoxinaniso lwe-inline zincede abavelisi beeseli zamafutha ukuba bafezekise impumelelo ebalulekileyo ekuxubeni kodaka lwe-catalyst. Ngokubeka iliso ngexesha lokwenyani kunye nolawulo olukrelekrele, uluhlu lokuguquguquka koxinzelelo lwe-slurry luye lwancitshiswa kakhulu ukusuka ku-±0.03 g/cm³ ukuya ku-±0.001 g/cm³. Olu phuculo longeza ngokuthe ngqo ukuguquguquka kwemveliso kunye nozinzo lokusebenza, ukwandisa uxinano lwamandla eeseli zamafutha kwishishini elinye nge-15%.
UPhucuko oluBalulekileyo lweMveliso
Ixesha lokuveliswa kwebhetshi enye lincitshisiwe, kunye nokonga ngonyaka okungaphezulu kwe-300,000 yeedola kwiindleko zempahla kunye nokuphinda kusebenze. Ngaphaya koko, ukusetyenziswa kweemitha zokuxinana kwe-inline kuye kwayiphucula yonke inkqubo. Idityaniswe neenkqubo ze-DCS, zenza ulawulo lwedijithali ngokupheleleyo ukusuka kulawulo lwefomula ukuya ekulandelekeni komgangatho, zenza isiseko sokuveliswa kweeseli zamafutha e-hydrogen.
Ukubaluleka Okunzulu kuShishino lwaMandla eHydrogen
Njengomthwali ongundoqo wamandla acocekileyo, iiseli ze-hydrogen fuel zijongene nemingeni emibini yokuphucula ukusebenza kunye nokunciphisa iindleko. Ukusetyenziswa kwetekhnoloji yemitha yoxinaniso lwe-inline ayisombululi kuphela iingxaki eziphambili zenkqubo kwimveliso ye-MEA kodwa ikwaqhuba uphuculo lwetekhnoloji kulo lonke ikhonkco loshishino lwamandla e-hydrogen.
