Kwi-Fraunhofer Institute for Machine Tools and Forming Technology IWU, abaphandi baphuhlisa ubuchwepheshe obuphambili bokwenza iinjini zeeseli zepetroli ngenjongo yokwenza kube lula ukuveliswa kwazo ngokukhawuleza nangokungabizi kakhulu. Ngenxa yesi sizathu, abaphandi be-IWU ekuqaleni bagxile ngqo entliziyweni yezi njini kwaye basebenza kwiindlela zokwenza iipleyiti ze-bipolar ezivela kwiifoyile zesinyithi ezibhityileyo. KwiHannover Messe, iFraunhofer IWU iza kubonisa ezi kunye neminye imisebenzi yophando lwenjini yeeseli zepetroli ethembisayo kunye nemoto yomdyarho yeSilberhummel.
Xa kufikwa ekuboneleleni ngamandla kwiinjini zombane, ii-fuel cells ziyindlela efanelekileyo yokongeza iibhetri ukwandisa uluhlu lokuqhuba. Nangona kunjalo, ukuvelisa ii-fuel cells kusaqhubeka nenkqubo ebiza kakhulu, ngoko ke kusekho iimodeli ezimbalwa zezithuthi ezisebenzisa obu buchwephesha bokuqhuba kwimarike yaseJamani. Ngoku abaphandi baseFraunhofer IWU basebenza kwisisombululo esingabizi kakhulu: “Sithatha indlela epheleleyo kwaye sijonge zonke izinto ezikwiinjini ze-fuel cell. Iqala ngokubonelela nge-hydrogen, ichaphazela ukhetho lwezinto ezibandakanyeka ngokuthe ngqo ekuveliseni umbane kwiiseli ze-fuel, kwaye ifikelela kwi-thermoregulation kwiseli ngokwayo nakwisithuthi siphela,” ucacisa uSören Scheffler, umphathi weprojekthi eFraunhofer IWU eChemnitz.
Njengenyathelo lokuqala, abaphandi bagxila entliziyweni yayo nayiphi na injini ye-fuel cell: "i-stack." Kulapho amandla eveliswa khona kwiiseli ezininzi ezihlanganisiweyo ezenziwe ngee-bipolar plates kunye nee-electrolyte membranes.
“Siphanda indlela esinokutshintsha ngayo iiplate ze-graphite bipolar zesiqhelo ngeefoyile zesinyithi ezibhityileyo. Oku kuya kwenza ukuba ii-stacks zenziwe ngokukhawuleza nangendlela engabizi kakhulu kwaye kuya kuphucula kakhulu imveliso,” utshilo uScheffler. Abaphandi bakwagxila ekuqinisekiseni umgangatho. Yonke into kwii-stacks ihlolwa ngokuthe ngqo kwinkqubo yokwenziwa. Oku kwenzelwe ukuqinisekisa ukuba kuphela iindawo ezihlolwe ngokupheleleyo ezingena kwi-stack.
Ngaxeshanye, iFraunhofer IWU ijonge ukuphucula amandla ee-stacks ukuze zilungelelane nokusingqongileyo kunye nemeko yokuqhuba. UScheffler ucacisa athi, “Ingcamango yethu kukuba ukuziqhelanisa nokuguquguquka kokusingqongileyo—okuncediswa yi-AI—kunokunceda ukonga i-hydrogen. Kwenza umahluko nokuba injini isetyenziswa kumaqondo obushushu aphezulu okanye aphantsi angaphandle, okanye nokuba isetyenziswa kumathafa okanye ezintabeni. Okwangoku, ii-stacks zisebenza kuluhlu oluchaziweyo, oluzinzileyo olungavumeli olu hlobo lokwenziwa ngcono okuxhomekeke kokusingqongileyo.”
Iingcali zeFraunhofer ziza kubonisa indlela yazo yophando ngomboniso wazo waseSilberhummel eHannover Messe ukususela nge-20 ukuya kwi-24 ka-Epreli, ngo-2020. I-Silberhummel isekelwe kwimoto yomdyarho eyayiyilwe yi-Auto Union AG ngeminyaka yoo-1940. Abaphuhlisi beFraunhofer IWU ngoku basebenzise iindlela ezintsha zokwenza imveliso yokwakha kwakhona le moto kunye nokudala umboniso wetekhnoloji yanamhlanje. Injongo yabo kukufaka iSilberhummel injini yombane esekelwe kubuchwepheshe beeseli zepetroli obuphambili. Le teknoloji sele iboniswe ngedijithali kwisithuthi eHannover Messe.
Umzimba weSilberhummel ngokwawo ungumzekelo wezisombululo ezintsha zokwenza kunye neenkqubo zokwenza eziphuhliswa ngakumbi eFraunhofer IWU. Nangona kunjalo, apha, ingqwalasela ikwimveliso engabizi kakhulu yeebhetshi ezincinci. Iphaneli yomzimba yeSilberhummel ayizange yenziwe ngoomatshini abakhulu ababandakanya ukusebenza okunzima ngezixhobo zentsimbi. Endaweni yoko, kwasetyenziswa iimolds ezingalunganga ezenziwe ngomthi olula ukucutshungulwa. Isixhobo somatshini esenzelwe le njongo sacinezela iphaneli yomzimba kwimold yomthi kancinci kancinci sisebenzisa i-mandrel ekhethekileyo. Iingcali zibiza le ndlela ngokuthi "ukwakheka okwandisiweyo." "Iphumela ekudalweni ngokukhawuleza kwezinto ezifunekayo kunendlela eqhelekileyo - nokuba ziifender, iihoods okanye kwanamacandelo asecaleni eetram. Ukwenziwa kwezixhobo ezisetyenziselwa ukwenza amalungu omzimba, umzekelo, kunokuthatha iinyanga ezininzi. Sasidinga ngaphantsi kweveki kwiimvavanyo zethu - ukusuka ekwenziweni kwemold yomthi ukuya kwiphaneli egqityiweyo," utshilo uScheffler.
