Mu rwego rwo gukora uturemangingo twa hydrogene fuel, Membrane Electrode Assembly (MEA) ni yo gice cy'ingenzi cyo guhindura ingufu, ikagena mu buryo butaziguye imikorere ya bateri n'igihe imara. Intambwe ya mbere yo gukora MEA binyuze mu kohereza ubushyuhe ni uguvanga slurry ya catalyst - intambwe y'ingenzi igira ingaruka ku bwiza bw'umusaruro wa nyuma. Iyi nzira isaba kuvanga neza Pt-C catalysts, solvents, na binders kugira ngo habeho uruvange ruhamye rukwirakwira neza.
Kuvanga bisanzwe birwana no kugenzura neza igipimo cya buri gice n'uko gikwirakwira, bigatera ibibazo nko gusiga ibirungo bitangana no kugabanuka k'imikorere ya catalytic mu ntambwe zikurikiraho.ibipimo by'ubucucike bw'umurongo itanga igisubizo cy’ingirakamaro, gifasha kugenzura neza ibipimo by’ibice n’ingaruka z’ikwirakwira binyuze mu gukurikirana mu buryo nyabwo impinduka z’ubucucike bw’urutare mu gihe nyacyo.
Lonnmeter Group, ikigo gikomeye mu gukora no gutanga ibipimo by’ubucucike bw’ibikoresho, cyamaze imyaka myinshi gitanga ibisubizo by’umwuga ku bakiriya ku isi yose. Ibi bisubizo byafashije inganda nyinshi, inganda z’amashanyarazi, n’ibigo bikora ibyuma kugabanya ikiguzi no kunoza imikorere.
Uruhare rw'ingenzi rwo kuvanga urumogi
Imikorere ya MEAs y’uturemangingo twa hydrogen fuel ishingiye cyane ku buryo ibintu bingana n’uko ibintu bihagaze neza. Urugero, ibintu bito bito bya anode bisaba 15% Pt-C catalyst ikwirakwijwe mu buryo bumwe mu buryo buvanze bw’amazi ya 40% deionized, 40% methanol, na 5% ionomer solution; ibintu bito bya cathode bisaba ingano nini ya catalyst (20%) na binder (10%). Iki gipimo nyacyo ntikigira ingaruka gusa ku miterere y’ibintu bito ahubwo kigira ingaruka ku buryo butaziguye ku ikwirakwizwa ry’ahantu hakora catalytic na proton conductivity.
Kugenzura ubucucike budakwiye bishobora gutera guhurirana kwa catalyst cyangwa sedimentation, bigatera ubugari butaringaniye bwa catalyst ipfundikiye ndetse n'imikorere ya bateri muri rusange. Urugero, ubucucike bwinshi bushobora kugaragaza ko catalyst cyangwa solvent exhydration ikabije, byongera ubucucike bw'urubura kandi bigatera inenge "ijisho ry'umuhondo" cyangwa "umwobo w'inyuma" mu gihe cyo gupfuka; ubucucike buke bushobora kugaragaza ko catalyst idahagije, ntitange ahantu hakwiye ho gukora kandi ikagabanya imikorere ya bateri.
Imbogamizi zo kugenzura ubucucike bw'ibinure gakondo
Uburyo gakondo bwo kuvanga ibinyabiziga bya catalyst bushingiye ku gupima intoki no gupima utari kuri interineti mu gihe cy’ibanze. Ubu buryo buri inyuma cyane y’ibikorwa byo mu gihe nyacyo—kubona ibisubizo by’ibizamini bivuye mu gupima akenshi bifata iminota 15-30, icyo gihe ibinyabiziga bishobora kuba byinjiye mu buryo bukurikira, bigatuma habaho imyanda myinshi yo kongera gukora.
Ibikorwa byakozwe n'intoki biragoye kubona uburyo uduce twa catalyst twa nanoscale tugenda duhurirana. Byongeye kandi, ibintu nk'impinduka z'ubushyuhe n'ihindagurika ry'ibinyabutabire bitera ihindagurika ry'ubucucike mu byuma, ibyo inzira gakondo zidashobora kwishyura mu gihe nyacyo, bikongera ibyago byo kudahinduka kw'ubuziranenge.
Ihame ry'imikorere n'inyungu za tekiniki
Kugira ngo bakemure izi mbogamizi, injeniyeri za Lonnmeter zakoze ibipimo by’ubucucike bw’amazi bishingiye ku ihame rya Coriolis force, bipima inshuro z’amazi ahindagurika kugira ngo babone amakuru y’ubucucike bw’amazi mu gihe nyacyo ku buryo bunoze kugeza kuri ± 0.001 g / cm³. Mu kuvanga urutare rwa hydrogen fuel cell, ibi bikoresho byo kugenzura neza bishobora gushyirwa aho basohokera ibigega cyangwa imiyoboro yo kuzenguruka kugira ngo bakomeze gukusanya amakuru y’ubucucike n’ubushyuhe, hamwe n’uburyo bwo kwishyura bukuraho ingaruka z’ubushyuhe ku bucucike.
Uretse ibipimo by'ubucucike bwa Coriolis, Lonnmeter yanakoze ibindi bipimo by'ubucucike mu murongo nka tuning fork density meters na ultrasonic density meters kugira ngo bitange sensors zigenzura ubucucike mu buryo bw'ubwenge ku mikorere itandukanye. Iyo ibonye ko ubucucike bwa cathode slurry burenze agaciro k'intego, sisitemu ihita ibarura ubucucike hanyuma ikongeramo ingano ikwiye ya solvent binyuze muri pompe ipima; iyo ubucucike buri hasi cyane, hongerwamo alcohol ya catalyst mother. Ubu buryo bwo kugenzura dynamic loop ntibukosora gusa ubucucike bwa formula ahubwo bunahanura ibibazo bishobora kubaho binyuze mu isesengura ry'amakuru ya kera. Iyo ihindagurika ry'ubucucike rirenze urugero, sisitemu itera alarms kugira ngo itere gutandukana ku buryo butari bumwe cyangwa gutandukana mu byiciro, birinda ko habaho impanuka nyinshi.
Ibisubizo byo Gukurikirana Ubucucike Buhoraho
Gukomera kw'uturemangingo twa lisansi
Ibipimo by’ubucucike bwa Lonnmeter byafashije abakora utwuma twa lisansi kugera ku ntambwe ikomeye mu kuvanga urusenda rwa catalyst. Binyuze mu igenzura ry’igihe nyacyo no kugenzura neza, ingano y’ihindagurika ry’ubucucike bwa lisansi yagabanutse cyane kuva kuri ± 0.03 g/cm³ kugera kuri ± 0.001 g/cm³. Iri terambere ryongera imiterere y’ibicuruzwa no kudahinduka kw’imikorere, byongera ubucucike bw’ingufu za lisansi z’ikigo kimwe ho 15%.
Iterambere ry'umusaruro ryazamutse cyane
Igihe cyo gukora kimwe cyagabanijwe, aho amafaranga yagabanutse ku mwaka arenga $300.000 mu bikoresho no kuvugurura ikoreshwa ryabyo. Byongeye kandi, gukoresha ibipimo by’ubucucike bw’imirongo byanogeje igikorwa cyose. Bihujwe na sisitemu za DCS, bituma habaho imicungire yuzuye y’ikoranabuhanga kuva ku gucunga formula kugeza ku gushakisha ubuziranenge, bigashyiraho urufatiro rwo gukora utunyangingo twa hydrogen fuel mu buryo bunini.
Akamaro Gakomeye ku Nganda z'Ingufu za Hydrogen
Nk’ingenzi mu gutwara ingufu zisukuye, uturemangingo twa hydrogen duhura n’imbogamizi ebyiri zo kunoza imikorere no kugabanya ikiguzi. Gukoresha ikoranabuhanga ryo gupima ubucucike bw’ingufu mu buryo burambuye ntabwo bikemura gusa ibibazo by’ingenzi mu mikorere mu musaruro wa MEA ahubwo binatuma habaho iterambere ry’ikoranabuhanga mu ruhererekane rw’inganda z’ingufu za hydrogen.
Niba ushakasensors z'imikorere ziri ku murongoKugira ngo ugabanye ibiciro no kongera imikorere myiza mu gukora ibikoresho byikora, Lonnmeter instrumentation instruments ni imwe mu mahitamo meza wagira.
