E-Fraunhofer Institute for Machine Tools and Forming Technology IWU, abacwaningi bathuthukisa ubuchwepheshe obuthuthukisiwe bokukhiqiza izinjini zamaseli kaphethiloli ngenhloso yokwenza kube lula ukukhiqizwa kwazo okusheshayo nokungabizi kakhulu. Ngenxa yalokhu, abacwaningi be-IWU ekuqaleni bagxila ngqo enhliziyweni yalezi zinjini futhi basebenza ezindleleni zokwenza amapuleti e-bipolar ngama-foil ensimbi amancane. E-Hannover Messe, i-Fraunhofer IWU izokhombisa le misebenzi yocwaningo lwenjini yamaseli kaphethiloli neminye ethembisayo ngemoto yomjaho i-Silberhummel.
Uma kukhulunywa ngokuhlinzeka ngamandla ezinjini zikagesi, amaseli kaphethiloli ayindlela efanelekile yokwengeza amabhethri ukuze kwandiswe ububanzi bokushayela. Kodwa-ke, ukukhiqiza amaseli kaphethiloli kusalokhu kuyinqubo ebiza kakhulu, ngakho-ke kusenezinhlobo ezimbalwa zezimoto ezinalobu buchwepheshe bokushayela emakethe yaseJalimane. Manje abacwaningi baseFraunhofer IWU basebenza ngesisombululo esingabizi kakhulu: “Sithatha indlela ephelele futhi sibheka zonke izingxenye enjinini yamaseli kaphethiloli. Kuqala ngokunikezwa kwe-hydrogen, kuthinta ukukhetha kwezinto ezihilelekile ngqo ekukhiqizeni ugesi kumaseli kaphethiloli, futhi kudlulela ekushiseni kweseli uqobo kanye nasemotweni iyonke,” kuchaza uSören Scheffler, umphathi wephrojekthi eFraunhofer IWU eChemnitz.
Njengesinyathelo sokuqala, abacwaningi bagxila enhliziyweni yanoma iyiphi injini yamaseli kaphethiloli: "isitaki." Yilapho amandla ekhiqizwa khona kumaseli amaningana ahlanganisiwe akhiwe ngamapuleti e-bipolar kanye nama-membrane e-electrolyte.
“Sicwaninga ukuthi singawashintsha kanjani amapuleti e-graphite bipolar avamile ngama-foil ensimbi amancane. Lokhu kuzokwenza ukuthi ama-stack akhiqizwe ngokushesha nangendlela engabizi kakhulu futhi kuzothuthukisa kakhulu umkhiqizo,” kusho uScheffler. Abacwaningi bagxile nasekuqinisekisweni kwekhwalithi. Yonke ingxenye ema-stack ihlolwa ngqo enkambisweni yokukhiqiza. Lokhu kuhloswe ukuqinisekisa ukuthi izingxenye ezihlolwe ngokugcwele kuphela ezingena esitakini.
Ngesikhathi esifanayo, i-Fraunhofer IWU ihlose ukuthuthukisa ikhono lama-stack lokuzivumelanisa nemvelo kanye nesimo sokushayela. UScheffler uyachaza, “Umbono wethu uwukuthi ukuzivumelanisa nezimo zemvelo ngendlela eguquguqukayo—futhi ngosizo lwe-AI—kungasiza ekusindiseni i-hydrogen. Kwenza umehluko ukuthi injini isetshenziswa emazingeni okushisa aphezulu noma aphansi angaphandle, noma ukuthi isetshenziswa emathafeni noma ezintabeni. Njengamanje, ama-stack asebenza endaweni yokusebenza echazwe kusengaphambili, engaguquki engavumeli lolu hlobo lokwenziwa ngcono okuncike emvelweni.”
Ochwepheshe beFraunhofer bazobonisa indlela yabo yokucwaninga ngombukiso wabo weSilberhummel eHannover Messe kusukela mhla zingama-20 kuya kumhla zingama-24 kuMbasa 2020. I-Silberhummel isekelwe emotweni yomjaho eyaklanywa yi-Auto Union AG ngawo-1940. Abathuthukisi be-Fraunhofer IWU manje sebesebenzise izindlela ezintsha zokukhiqiza ukwakha kabusha le moto nokudala umboniso wobuchwepheshe besimanje. Inhloso yabo ukuhlomisa iSilberhummel ngenjini kagesi esekelwe kubuchwepheshe obuthuthukisiwe be-fuel cell. Lobu buchwepheshe buzovele bufakwe emotweni ngedijithali eHannover Messe.
Umzimba we-Silberhummel ngokwawo uyisibonelo sezixazululo ezintsha zokukhiqiza kanye nezinqubo zokwakha ezithuthukiswayo eFraunhofer IWU. Nokho, lapha, ukugxila kusekukhiqizweni okungabizi kakhulu kosayizi abancane be-batch. Iphaneli yomzimba ye-Silberhummel ayizange yakhiwe ngokucindezela okukhulu okubandakanya ukusebenza okuyinkimbinkimbi ngamathuluzi ensimbi ahlanganisiwe. Esikhundleni salokho, kwasetshenziswa izikhunta ezingezinhle ezenziwe ngokhuni olulula ukuzisebenzisa. Ithuluzi lomshini elenzelwe le njongo lacindezela iphaneli yomzimba esikhumbeni sokhuni kancane kancane kusetshenziswa i-mandrel ekhethekile. Ochwepheshe babiza le ndlela ngokuthi “ukwakheka okwengeziwe.” “Kuphumela ekudalweni okusheshayo kakhulu kwezingxenye ezifunwayo kunendlela evamile—kungakhathaliseki ukuthi ama-fender, ama-hood noma ngisho nezingxenye eziseceleni zama-tram. Ukwenziwa okuvamile kwamathuluzi asetshenziselwa ukwakha izingxenye zomzimba, isibonelo, kungathatha izinyanga eziningana. Sasidinga isikhathi esingaphansi kwesonto ukuze sivivinye—kusukela ekwenziweni kwesikhunta sokhuni kuya ephanelini eliqediwe,” kusho uScheffler.
Ungaqiniseka ukuthi abahleli bethu baqapha ngokucophelela yonke impendulo ethunyelwe futhi bazokwenza okufanele. Imibono yakho ibalulekile kithi.
Ikheli lakho le-imeyili lisetshenziselwa ukwazisa umamukeli ukuthi ngubani othumele i-imeyili. Ikheli lakho noma ikheli lomamukeli ngeke lisetshenziswe nganoma iyiphi enye injongo. Ulwazi olufakayo luzovela kumyalezo wakho we-imeyili futhi alugcinwa yi-Tech Xplore nganoma iyiphi indlela.
Le sayithi isebenzisa amakhukhi ukusiza ngokuzulazula, ukuhlaziya ukusetshenziswa kwakho kwezinsizakalo zethu, kanye nokunikeza okuqukethwe okuvela kubantu besithathu. Ngokusebenzisa isayithi lethu, uyavuma ukuthi uyifundile futhi uyayiqonda inqubomgomo yethu yobumfihlo kanye nemigomo yokusebenzisa.
