E-Fraunhofer Institute for Machine Tool and Molding Technology IWU, abacwaningi bathuthukisa ubuchwepheshe obuthuthukisiwe bokukhiqiza izinjini zamaseli kaphethiloli ukuze kube lula ukukhiqizwa kwenqwaba okusheshayo, okungabizi kakhulu. Kuze kube manje, abacwaningi be-IWU baqale bagxila enhliziyweni yalezi zinjini futhi bacwaninga 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 nge-Silberhummel Racing.
Uma kukhulunywa ngokunika amandla izinjini zikagesi, ama-fuel cell ayindlela ekahle yokwengeza amabhethri ukukhulisa ibanga lokushayela. Nokho, ukukhiqiza ama-fuel cell kuseyinqubo ebizayo, ngakho-ke asekhona amamodeli ambalwa kakhulu asebenzisa lobu buchwepheshe bokushayela emakethe yaseJalimane. Manje abacwaningi be-Fraunhofer IWU basebenzela isixazululo esingabizi kakhulu: “Sisebenzisa indlela ephelele ukuze sihlole zonke izingxenye zenjini yamaseli kaphethiloli. Into yokuqala okufanele yenziwe ukuhlinzeka nge-hydrogen, ethinta ukukhethwa kwezinto zokwakha. Ibandakanyeka ngqo ekuphehleni amandla kaphethiloli futhi idlulela ku-fuel cell uqobo kanye nokulawulwa kwezinga lokushisa kwayo yonke imoto.” Umphathi wephrojekthi we-Chemnitz Fraunhofer IWU uSören Scheffler wachaza.
Esinyathelweni sokuqala, abacwaningi bagxile enhliziyweni yanoma iyiphi injini ye-fuel cell: "isitaki samaseli kaphethiloli." Yilapho amandla enziwa khona kumabhethri amaningi astakiwe akhiwe ngamapuleti e-bipolar kanye nolwelwesi lwama-electrolyte.
Scheffler wathi: “Siphenya ukuthi singawashintsha kanjani amapuleti avamile e-graphite bipolar sifake ucwecwe lwensimbi oluncane. Lokhu kuzokwenza ukuthi izitaki zikhiqizwe ngobuningi ngokushesha nangokwezomnotho futhi kukhuphule izinga lokukhiqiza.” Abacwaningi nabo bazibophezele ekuqinisekiseni ikhwalithi. Hlola zonke izingxenye kusitaki ngokuqondile ngesikhathi senqubo yokukhiqiza. Lokhu okokuqinisekisa ukuthi izingxenye ezihlolwe ngokugcwele kuphela ezingangena kustaki.
Ngesikhathi esifanayo, i-Fraunhofer IWU ihlose ukuthuthukisa ikhono likashimula lokujwayela imvelo nezimo zokushayela. UScheffler wachaza: “Umbono wethu ukuthi ngosizo lwe-AI, ukulungisa okuguquguqukayo kwemvelo kungasindisa i-hydrogen. Noma ngabe isebenzisa injini emazingeni okushisa aphezulu noma aphansi, noma isebenzisa injini ethafeni noma endaweni yokushisa ephezulu, izohluka. Okwamanje, isitaki sisebenza ngaphakathi kwebanga lokusebenza elinqunyiwe elinqunyiwe, elingakuvumeli ukulungiselelwa okunjalo okuncike endaweni.”
Ochwepheshe be-Fraunhofer Laboratory bazokwethula izindlela zabo zocwaningo embukisweni we-Silberhummel e-Hannover Messe kusukela ngomhla ka-April 20 kuya zingama-24, 2020. I-Silberhummel isekelwe emotweni yomjaho eyaklanywa i-Auto Union ngeminyaka yawo-1940. Abathuthukisi be-Fraunhofer IWU manje sebesebenzise izindlela ezintsha zokukhiqiza ukuze bakhe kabusha imoto futhi bakhe izibonisi zobuchwepheshe besimanje. Umgomo wabo uwukuhlomisa iSilberhummel ngenjini kagesi esuselwe kubuchwepheshe obuthuthukisiwe be-fuel cell. Lobu buchwepheshe buvezwe ngedijithali e-Hannover Messe.
Umzimba we-Silberhummel ngokwawo futhi uyisibonelo sezixazululo ezintsha zokukhiqiza nezinqubo zokubumba ezithuthukiswe nguFraunhofer IWU. Kodwa-ke, okugxilwe kukho lapha ukukhiqiza izindleko eziphansi ngamaqoqo amancane. Amaphaneli omzimba we-Silberhummel awakhiwe imishini emikhulu yokugxiviza, ehlanganisa imisebenzi eyinkimbinkimbi yamathuluzi ensimbi. Kunalokho, kusetshenziswa isikhunta sesifazane esenziwe ngokhuni okulula ukusicubungula. Ithuluzi lomshini elenzelwe le njongo lisebenzisa i-mandrel ekhethekile ukucindezela iphaneli yomzimba kancane kancane esikhunjeni sokhuni. Ochwepheshe babiza le ndlela ngokuthi "i-incremental shape". “Uma kuqhathaniswa nendlela evamile, kungakhathaliseki ukuthi i-fender, i-hood, noma uhlangothi lwethilamu, le ndlela ingakhiqiza izingxenye ezidingekayo ngokushesha. Isibonelo, ukwenziwa okuvamile kwamathuluzi asetshenziswa ukwenza izitho zomzimba Kungathatha izinyanga ezimbalwa. Sidinga isikhathi esingaphansi kwesonto kusukela ekwenziweni kwesikhunta sokhuni kuya ekuhlolweni kwephaneli eliqediwe,” kusho uScheffler.
