E-Fraunhofer Institute for Machine Tools and Forming Technology IWU, abacwaningi bathuthukisa ubuchwepheshe obuthuthukisiwe bokukhiqiza izinjini zamangqamuzana kaphethiloli ngenhloso yokwenza lula ukukhiqizwa kwazo kwe-serial okusheshayo nokungabizi. Kuze kube manje, abacwaningi be-IWU baqale bagxile ngqo enhliziyweni yalezi zinjini futhi basebenzela izindlela zokwenza amapuleti e-bipolar kusuka kumafoyili ensimbi amancane. E-Hannover Messe, i-Fraunhofer IWU izokhombisa lezi kanye neminye imisebenzi ethembisayo yocwaningo lwenjini yamaseli kaphethiloli ngemoto yomjaho i-Silberhummel.
Uma kuziwa ekunikezeni amandla ezinjini zikagesi, ama-fuel cell ayindlela ekahle yokwengeza amabhethri ukuze kwandiswe ibanga lokushayela. Kodwa-ke, ukukhiqiza ama-fuel cell kusalokhu kuyinqubo ebiza kakhulu, ngakho-ke asemancane amamodeli ezimoto analobu buchwepheshe bokushayela emakethe yaseJalimane. Manje abacwaningi bakwa-Fraunhofer IWU basebenzela isixazululo esingabizi kakhulu: “Sithatha indlela ephelele futhi sibheke zonke izingxenye zenjini yamaseli kaphethiloli. Iqala ngokuhlinzekwa kwe-hydrogen, ithinte ukukhethwa kwezinto ezithintekayo ngokuqondile ekuphehleni ugesi kuma-fuel cell, futhi idlulele ku-thermoregulation esitokisini uqobo nasemotweni yonkana,” kuchaza uSören Scheffler, umphathi wephrojekthi kwaFraunhofer. IWU eChemnitz.
Njengesinyathelo sokuqala, abacwaningi bagxila enhliziyweni yanoma iyiphi injini ye-fuel cell: "isitaki." Yilapho amandla enziwa khona enanini lamaseli astakiwe akhiwe ngamapuleti e-bipolar kanye nolwelwesi lwama-electrolyte.
“Sicwaninga ukuthi singawashintsha kanjani amapuleti avamile e-graphite bipolar sifake ucwecwe lwensimbi oluncane. Lokhu kuzokwenza ukuthi izitaki zenziwe ngokushesha nangokwezomnotho ngezinga elikhulu futhi kuzothuthukisa kakhulu umkhiqizo,” kusho uScheffler. Abacwaningi nabo bagxile ekuqinisekiseni ikhwalithi. Yonke ingxenye ezitaki ihlolwa ngokuqondile enqubweni yokukhiqiza. Lokhu kuhloswe ngakho ukuqinisekisa ukuthi izingxenye kuphela ezihloliwe ngokugcwele ezingena esitaki.
Ngokuhambisanayo, i-Fraunhofer IWU ihlose ukuthuthukisa ikhono lezitaki ukuze livumelane nemvelo kanye nesimo sokushayela. U-Scheffler uyachaza, “Umbono wethu ukuthi ukuzivumelanisa ngokuguquguqukayo neziguquguqukayo zemvelo—futhi kusizwa i-AI—kungasiza ukonga i-hydrogen. Kwenza umehluko ukuthi injini isetshenziswa emazingeni okushisa aphezulu noma aphansi ngaphandle, noma ngabe isetshenziswa emathafeni noma ezintabeni. Njengamanje, izitaki zisebenza ebangeni lokusebenza elichazwe ngaphambilini, elingaguquki elingakuvumeli lolu hlobo lokusebenzisa ngokugcwele okuncike endaweni.”
Ochwepheshe be-Fraunhofer bazobonisa indlela yabo yocwaningo ngombukiso wabo we-Silberhummel e-Hannover Messe kusukela ngo-April 20 kuya ku-24, 2020. I-Silberhummel isuselwe emotweni yomjaho eyaklanywa i-Auto Union AG ngeminyaka yawo-1940s. Abathuthukisi be-Fraunhofer IWU manje sebesebenzise izindlela ezintsha zokukhiqiza ukuze bakhe kabusha le moto futhi bakhe umbonisi wobuchwepheshe besimanje. Inhloso yabo wukugqokisa iSilberhummel ngenjini kagesi esekelwe kubuchwepheshe obusezingeni eliphezulu be-fuel cell. Lobu buchwepheshe buzovele buvezwe ngedijithali emotweni e-Hannover Messe.
Umzimba we-Silberhummel ngokwawo futhi uyisibonelo sezixazululo ezintsha zokukhiqiza kanye nezinqubo zokwakheka ezithuthukiswayo kwa-Fraunhofer IWU. Lapha, nokho, kugxilwe ekwenziweni okungabizi kakhulu kwamasayizi amaqoqo amancane. Iphaneli yomzimba ye-Silberhummel ayizange yakheke ngomshini wokunyathelisa omkhulu ohlanganisa ukusebenza okuyinkimbinkimbi ngamathuluzi ensimbi ekhonjiwe. Kunalokho, kwasetshenziswa isikhunta esibi esenziwe ngokhuni olukwazi ukuhleleka kalula. Ithuluzi lomshini elakhelwe le njongo licindezele iphaneli yomzimba esikhunjeni sokhuni kancane kancane lisebenzisa i-mandrel ekhethekile. Ochwepheshe babiza le ndlela ngokuthi “ukwakheka okukhulayo.” “Kuholela ekudalweni okushesha kakhulu kwezakhi ezifunwayo kunendlela evamile—kungaba ama-fender, ama-hood noma izingxenye eziseceleni zamathilamu. Ukwakhiwa okuvamile kwamathuluzi asetshenziswa ukwenza izitho zomzimba, ngokwesibonelo, kungathatha izinyanga ezimbalwa. Sasidinga isikhathi esingaphansi kwesonto ukuze sihlole—kusukela ekwenziweni kwesikhunta sokhuni kuya ephanelini eliqediwe,” kusho uScheffler.
