Mu ruganda rukora ingufu za hydrogène, uruganda rwa Membrane Electrode Assembly (MEA) rukora nk'ibanze mu guhindura ingufu, bikagaragaza neza imikorere ya bateri n'igihe cyo kubaho. Intambwe yambere yo kubyaza umusaruro MEA binyuze mu guhererekanya ubushyuhe ni catalizator ivanze-intambwe ikomeye igira ingaruka nziza kubicuruzwa byanyuma. Iyi nzira isaba kuvanga neza catalizike ya Pt-C, ibishishwa, hamwe na binders kugirango bibe bivanze kimwe bivanze.
Gavangavanga gakondo kurugamba rwo kugenzura neza igipimo cya buri kintu hamwe no gutatanya leta, biganisha kubibazo nkibifuniko bitaringaniye kandi bigabanya ibikorwa bya catalitiki mu ntambwe zikurikira. Porogaramu yauburebure bwa metero itanga igisubizo cyibanze, igufasha kugenzura neza ibipimo byingaruka ningaruka zo gukwirakwiza binyuze mugihe nyacyo cyo kugenzura impinduka zuzuye.
Itsinda rya Lonnmeter, rikora cyane kandi ritanga metero zingana, ryatanze imyaka mirongo itanga ibisubizo byumwuga kubakiriya kwisi yose. Ibi bisubizo byafashije inganda nyinshi zinganda, inganda zamashanyarazi, ninganda zibyuma kugabanya ibiciro no kuzamura imikorere.
Uruhare Rukuru rwo Kuvanga Byoroheje
Imikorere ya hydrogène ya selile selile MEAs biterwa cyane nuburinganire nogukomera kwa catalizator. Kurugero, ibishishwa bya anode bisaba 15% ya catalizator ya Pt-C ikwirakwizwa kimwe mumashanyarazi avanze ya 40% yamazi ya deionion, 40% methanol, na 5% ionomer; cathode slurries isaba umubare munini wa catalizator (20%) na binder (10%). Iri gereranya risobanutse neza ntirigira ingaruka gusa kumiterere yumubiri ahubwo rifite uruhare runini mugukwirakwiza imbuga za catalitiki ikora hamwe na proton.
Kugenzura ubucucike budakwiye birashobora gutera catalizator agglomeration cyangwa gutembera, bikavamo umubyimba utaringaniye wa catalizator yatwikiriwe ndetse nibikorwa bya bateri muri rusange. Kurugero, ubucucike buri hejuru bushobora kwerekana catalizator ikabije cyangwa guhumeka neza, kongera ubukonje bwihuse no gutera "igishishwa cya orange" cyangwa "pinhole" mugihe cyo gutwikira; ubucucike buke burashobora kwerekana catalizator idahagije, kunanirwa gutanga imbuga zihagije no kugabanya imikorere ya bateri.
Imipaka ya gakondo ya Slurry Igenzura
Gakondo ya catalizator slurry kuvanga ishingiye kubipima intoki no gupima kumurongo mubanze. Ubu buryo bukurikira inyuma yigihe-cyane - kubona ibisubizo byikizamini bivuye mu cyitegererezo akenshi bifata iminota 15-30, icyo gihe icyo gihe gishobora kuba cyarinjiye muburyo bukurikira, biganisha ku myanda myinshi yo gukora.
Ibikorwa byintoki birarwana no kumenya nanoscale catalizator agace ka agglomeration. Byongeye kandi, ibintu nkimihindagurikire yubushyuhe hamwe no guhumeka bikabije bitera ihindagurika ryinshi ryimyuka ihindagurika, inzira gakondo ntishobora kwishyurwa mugihe nyacyo, bikarushaho gukaza umurego ingaruka ziterwa n’ihungabana.
Ihame ryakazi nibyiza bya tekiniki
Kugira ngo ibyo bibazo bikemuke, injeniyeri za Lonnmeter zateje imbere uburebure bwa metero zishingiye ku ihame ry’ingufu za Coriolis, zipima inshuro zinyeganyega kugira ngo zibone amakuru nyayo yuzuye kandi yuzuye kugeza kuri 0.001 g / cm³. Mu kuvanga bidatinze ingirabuzimafatizo ya hydrogène, ibyo bikoresho byo kugenzura neza birashobora gushyirwaho ahasohoka kuvanga ibigega cyangwa imiyoboro ikwirakwiza kugirango bikomeze gukusanya amakuru y’ubucucike n’ubushyuhe, hamwe na algorithms y’indishyi ikuraho ingaruka z’ubushyuhe ku bwinshi.
Kurenga metero yubucucike bwa Coriolis, Lonnmeter yateje imbere kandi ubundi burebure bwa metero zingana nko guhuza metero yubucucike bwa metero na metero ya ultrasonic yubucucike kugirango itange ibyuma byubwenge bikurikirana mubikorwa bitandukanye. Iyo ubonye ko ubucucike bwa cathode burenze agaciro kagenewe, sisitemu ihita ibara gutandukana kandi ikongeramo urugero rukwiye rwumuti ukoresheje pompe yo gupima; niba ubucucike buri hasi cyane, byabanje gutatanya catalizator inzoga ziyongera. Igenzura rya dinamike ntirishobora gukosora gusa gutandukana ahubwo rirahanura ibibazo bishobora kubaho hifashishijwe isesengura ryamateka. Iyo ihindagurika ryubucucike rirenze imbibi, sisitemu itera impuruza kugirango ihite itandukana cyangwa itandukanyirizo ryicyiciro, irinde impanuka nziza zicyiciro.
Ibisubizo byo Gukomeza Ubucucike
Kongera ingufu za selile
Lonnmeter inline yubucucike bwafashije abakora lisansi kugera kubintu byingenzi muguhuza catalizike. Binyuze mu kugenzura-igihe no kugenzura ubwenge, intera ihindagurika yubucucike bwaragabanutse cyane kuva kuri ± 0.03 g / cm³ kugeza kuri 0.001 g / cm³. Iri terambere ryongera mu buryo butaziguye ibicuruzwa no guhuza imikorere, byongera ingufu za selile yingufu za entreprise imwe 15%.
Kunoza kuburyo bugaragara umusaruro
Igihe cyo gukora icyiciro kimwe cyaragabanijwe, aho kuzigama buri mwaka birenga 300.000 by'amadolari y'ibikoresho no gukora. Byongeye kandi, ikoreshwa rya metero yubucucike bwa metero yahinduye inzira yose. Bishyizwe hamwe na sisitemu ya DCS, bashoboza gucunga neza sisitemu kuva mubuyobozi bwa formula kugeza kurwego rwiza, bigashyiraho urufatiro runini rwa hydrogène nini ya selile.
Akamaro gakomeye ku nganda za hydrogène
Nkibintu byingenzi bitwara ingufu zisukuye, selile ya hydrogène ihura nibibazo bibiri byo kunoza imikorere no kugabanya ibiciro. Ikoreshwa rya tekinoroji ya metero yubucucike ntabwo ikemura gusa ibibazo byingenzi byibanze mu musaruro wa MEA ahubwo binateza imbere ikoranabuhanga murwego rwose rwinganda zingufu za hydrogène.
Niba ushakainkugabanya ibiciro no kongera imikorere mubikorwa byikora, Lonnmeter ibikoresho byubwenge nimwe mubyo wahisemo byiza. Isosiyete iratangaIngero 100 z'ubuntu kwisi yose- umubare ni muto, kora vuba! Twandikire kugirango tubone igisubizo cyigenga kandi dusabe ibyitegererezo kubuntu.
