Ubwoko bushya bwa plaque ya bipolar ikozwe mu gapapuro k'icyuma gato kakozwe mu cyuma gikozwe mu gasanduku k'amavuta

Mu kigo cya Fraunhofer Institute for Machine Tools and Molding Technology IWU, abashakashatsi barimo gutegura ikoranabuhanga rigezweho ryo gukora moteri za lisansi kugira ngo byorohereze umusaruro mwinshi kandi uhendutse. Kugira ngo ibyo bigerweho, abashakashatsi ba IWU babanje kwibanda ku mutima w’izi moteri kandi barimo kwiga uburyo bwo gukora plaque za bipolar mu byuma bito. Muri Hannover Messe, Fraunhofer IWU izerekana ibi n’ibindi bikorwa by’ubushakashatsi bya moteri za lisansi bifite icyizere hamwe na Silberhummel Racing.
Ku bijyanye no gukoresha moteri z'amashanyarazi, utubumbe twa lisansi ni uburyo bwiza bwo kongera bateri kugira ngo bongere ingano y'imodoka. Ariko, gukora utubumbe twa lisansi biracyari inzira ihenze, bityo haracyari ubwoko buke cyane bukoresha ubu buryo bwo gutwara ku isoko ry'Ubudage. Ubu abashakashatsi ba Fraunhofer IWU barimo gukora ku gisubizo gihendutse: “Dukoresha uburyo buhuriweho mu kwiga ibice byose biri muri moteri ya lisansi. Ikintu cya mbere cyo gukora ni ugutanga hydrogen, igira ingaruka ku mahitamo y'ibikoresho. Igira uruhare rutaziguye mu gutanga ingufu za lisansi kandi ikagera no ku tubumbe twa lisansi ubwatwo no ku mikorere y'ubushyuhe bw'imodoka yose.” Umuyobozi w'umushinga wa Chemnitz Fraunhofer IWU, Sören Scheffler, yasobanuye.
Mu ntambwe ya mbere, abashakashatsi bibanze ku mutima wa moteri iyo ari yo yose ikoresha lisansi: "umuvuduko w'uturemangingo tw'isansi." Aha niho ingufu zikorerwa muri bateri nyinshi zigizwe n'ibice bya bipolar na electrolyte membranes.
Scheffler yagize ati: “Turimo gukora ubushakashatsi ku buryo twasimbuza plaque gakondo za grafiti bipolar hamwe n’udupapuro tw’icyuma duto. Ibi bizatuma uduce duto dukorwa ku bwinshi vuba kandi mu buryo buhendutse kandi twongere umusaruro cyane.” Abashakashatsi kandi biyemeje kugenzura ubuziranenge. Reba buri gice kiri muri aka gace mu buryo butaziguye mu gihe cyo gukora. Ibi ni ukugira ngo harebwe ko ibice byose bigenzuwe neza ari byo byonyine bishobora kwinjira muri ako gace.
Muri icyo gihe, Fraunhofer IWU igamije kunoza ubushobozi bw'umuyoboro w'amazi mu guhuza ibidukikije n'imiterere y'imodoka. Scheffler yasobanuye ati: “Igitekerezo cyacu ni uko hifashishijwe ubuhanga bwo gukora isuku, guhindura ibidukikije mu buryo buhindagurika bishobora kurokora hydrogen. Byaba ari ugukoresha moteri ku bushyuhe buri hejuru cyangwa buke, cyangwa gukoresha moteri iri ahantu hashyushye cyane cyangwa ahantu hari ubushyuhe bwinshi, bizahinduka. Kuri ubu, agace gakora mu rugero rudahinduka rw'imikorere, rutemerera ibidukikije gukora neza.”
Impuguke zo muri Laboratwari ya Fraunhofer zizagaragaza uburyo bwazo bw'ubushakashatsi mu imurikagurisha rya Silberhummel muri Hannover Messe kuva ku ya 20 kugeza ku ya 24 Mata 2020. Silberhummel ishingiye ku modoka y'amasiganwa yakozwe na Auto Union mu myaka ya 1940. Abahanga mu bya Fraunhofer IWU ubu bakoresheje uburyo bushya bwo gukora kugira ngo bongere kubaka iyi modoka no gukora ikoranabuhanga rigezweho. Intego yabo ni uguha Silberhummel moteri y'amashanyarazi ishingiye ku ikoranabuhanga rigezweho rya lisansi. Iri koranabuhanga ryateguwe mu buryo bw'ikoranabuhanga muri Hannover Messe.
Umubiri wa Silberhummel ubwawo ni urugero rw'ibisubizo bishya byo gukora no gushushanya byatejwe imbere na Fraunhofer IWU. Ariko, icyo twibandaho hano ni ugukora ku giciro gito mu byiciro bito. Udupira tw'umubiri wa Silberhummel ntabwo dukorwa n'imashini nini zo gusiga, zikoresha ibikoresho by'icyuma bikozwe mu cyuma. Ahubwo, hakoreshwa ifiriti y'ingore ikozwe mu giti cyoroshye gutunganya. Igikoresho cy'imashini cyagenewe iyi ntego gikoresha mandrel yihariye kugira ngo gikandagire igice cy'umubiri buhoro buhoro ku ifiriti y'igiti. Impuguke ziyita "ishusho y'inyongera". "Ugereranyije n'uburyo gakondo, bwaba ari fender, hood, cyangwa uruhande rwa tram, ubu buryo bushobora gukora ibice bikenewe vuba. Urugero, gukora ibikoresho bisanzwe bikoreshwa mu gukora ibice by'umubiri. Bishobora gufata amezi menshi. Dukeneye igihe kitarenze icyumweru kuva ifiriti y'igiti ikorwa kugeza igeragezwa ry'igice cyarangiye," Scheffler yagize ati.
