Mu gawo lopanga ma cell a hydrogen fuel, Membrane Electrode Assembly (MEA) imagwira ntchito ngati gawo lofunikira pakusintha mphamvu, zomwe zimatsimikiza mwachindunji momwe batire imagwirira ntchito komanso nthawi yake yogwiritsira ntchito. Gawo loyamba la kupanga MEA kudzera mu kusamutsa kutentha ndi kusakaniza kwa catalyst slurry—gawo lofunika kwambiri lomwe limakhudza mtundu wa chinthu chomaliza. Njirayi imafuna kusakaniza bwino kwa Pt-C catalysts, solvents, ndi ma binders kuti apange chisakanizo chokhazikika chofalikira mofanana.
Kusakaniza kwachikhalidwe kumavuta kuwongolera bwino kuchuluka kwa gawo lililonse ndi momwe limafalikira, zomwe zimapangitsa kuti pakhale mavuto monga kupendekera kosagwirizana komanso kuchepa kwa ntchito yothandiza pakapita nthawi.mita yozungulira imapereka njira yopambana, zomwe zimathandiza kuwongolera molondola kuchuluka kwa zigawo ndi zotsatira za kufalikira kudzera mukuwunika nthawi yeniyeni kusintha kwa kuchuluka kwa slurry.
Lonnmeter Group, kampani yopanga komanso yogulitsa ma inline density meters, yadzipereka kwa zaka zambiri kupereka mayankho aukadaulo kwa makasitomala padziko lonse lapansi. Mayankho awa athandiza mafakitale ambiri, mafakitale amagetsi, ndi mabizinesi azitsulo kuchepetsa ndalama ndikuwonjezera magwiridwe antchito.
Udindo Wofunika Kwambiri wa Kusakaniza Madzi Oundana
Kugwira ntchito kwa ma MEA amafuta a hydrogen kumadalira kwambiri kufanana ndi kukhazikika kwa ma catalyst slurries. Mwachitsanzo, ma anode slurries amafuna 15% Pt-C catalyst yomwe imafalikira mofanana mu solvent yosakanikirana ya 40% deionized water, 40% methanol, ndi 5% ionomer solution; ma cathode slurries amafuna kuchuluka kwa catalyst (20%) ndi binder (10%). Chiŵerengero cholondola ichi sichimangokhudza mawonekedwe enieni a slurry komanso chimakhudza mwachindunji kufalikira kwa malo ogwirira ntchito a catalytic ndi proton conductivity.
Kulamulira kosayenera kwa kachulukidwe ka zinthu kungayambitse kusonkhana kwa catalyst kapena sedimentation, zomwe zimapangitsa kuti catalyst yokhala ndi zokutira ikhale yosiyana komanso kuti batire lonse ligwire ntchito bwino. Mwachitsanzo, kuchuluka kwa kachulukidwe ka zinthu kungasonyeze kuti catalyst kapena solvent imatuluka kwambiri, kuonjezera kukhuthala kwa slurry ndikuyambitsa zolakwika za "peel ya lalanje" kapena "pinhole" panthawi yopaka; kuchuluka kwa kachulukidwe ka zinthu kungasonyeze kuti catalyst sikokwanira, kulephera kupereka malo okwanira ochitirapo kanthu komanso kuchepetsa magwiridwe antchito a batri.
Zoletsa za Kulamulira Kuchulukana kwa Madzi a Madzi a Chikhalidwe
Kusakaniza kwachikhalidwe kwa catalyst slurry kumadalira kuyeza pamanja ndi kuyesa popanda intaneti mu gawo loyamba. Njira iyi imachedwa kwambiri munthawi yeniyeni - kupeza zotsatira za mayeso kuchokera ku zitsanzo nthawi zambiri kumatenga mphindi 15-30, pomwe nthawi yomwe slurry ikhoza kukhala italowa munjira yotsatira, zomwe zimapangitsa kuti pakhale kutayika kwakukulu kwa ntchito yokonzanso.
Kugwira ntchito pamanja kumavuta kuzindikira kusonkhana kwa tinthu tating'onoting'ono ta nanoscale catalyst. Kuphatikiza apo, zinthu monga kusintha kwa kutentha ndi kusungunuka kwa solvent zimayambitsa kusinthasintha kwa kuchuluka kwa matope, zomwe njira zachikhalidwe sizingathe kuzikwaniritsa nthawi yeniyeni, zomwe zimawonjezera chiopsezo cha kusakhazikika kwa khalidwe.
Mfundo Yogwirira Ntchito ndi Ubwino Waukadaulo
Pofuna kuthana ndi mavutowa, mainjiniya a Lonnmeter adapanga mita yoyezera kuchuluka kwa madzi pogwiritsa ntchito mfundo ya mphamvu ya Coriolis, yomwe imayesa kuchuluka kwa kugwedezeka kwa madzi kuti ipeze deta yeniyeni yokhudzana ndi kuchuluka kwa madzi molondola mpaka ±0.001 g/cm³. Mu kusakaniza kwa slurry ya hydrogen fuel cell, zida zowunikira izi zolondola kwambiri zitha kuyikidwa pamalo otulukira matanki osakaniza kapena mapaipi oyendera kuti zisonkhanitse deta ya kuchuluka ndi kutentha mosalekeza, ndi njira zolipirira zomwe zimachotsa mphamvu ya kutentha pa kuchuluka kwa madzi.
Kupitilira pa Coriolis density meters, Lonnmeter yapanganso ma inline density meters ena monga tuning fork density meters ndi ultrasonic density meters kuti ipereke ma intelligent density monitoring sensors a mikhalidwe yosiyanasiyana yogwirira ntchito. Akazindikira kuti cathode slurry density yapitirira mtengo womwe ukuyembekezeka, makinawo amawerengera okha kupotoka ndikuwonjezera kuchuluka koyenera kwa solvent kudzera mu metering pump; ngati density ili yotsika kwambiri, catalyst mother liquor yomwe yafalikira kale imawonjezeredwa. Dynamic loop control iyi sikuti imangokonza zolakwika za formula komanso imalosera mavuto omwe angakhalepo kudzera mu kusanthula deta yakale. Pamene kusinthasintha kwa density kudutsa malire, makinawo amachititsa ma alarm kuti ayambe kufalikira kosafanana kapena kulekanitsidwa kwa gawo, kupewa ngozi zamtundu wa batch.
Zotsatira za Kuwunika Kosalekeza kwa Kachulukidwe
Kukhazikika kwa Maselo a Mafuta Owonjezera
Mamita olemera a Lonnmeter athandiza opanga ma cell amafuta kupeza njira zazikulu zogwirira ntchito posakaniza ma catalyst slurry. Kudzera mu kuyang'anira nthawi yeniyeni komanso malamulo anzeru, kuchuluka kwa ma slurry density fluctuation kwachepetsedwa kwambiri kuchokera ku ±0.03 g/cm³ mpaka ±0.001 g/cm³. Kusintha kumeneku kumawonjezera mwachindunji kukhazikika kwa malonda ndi magwiridwe antchito, ndikuwonjezera kuchuluka kwa mphamvu ya ma cell amafuta a kampani imodzi ndi 15%.
Kugwira Ntchito Mwachangu Kwambiri
Nthawi yopangira imodzi yafupikitsidwa, ndipo ndalama zosungidwa pachaka zopitilira $300,000 pazinthu ndi ndalama zokonzanso. Kuphatikiza apo, kugwiritsa ntchito mita yozungulira kwapangitsa kuti ntchito yonse ikhale yabwino. Kuphatikiza ndi machitidwe a DCS, zimathandiza kuyang'anira bwino kuyambira pa kasamalidwe ka fomula mpaka kutsata bwino, ndikuyika maziko opangira maselo akuluakulu a hydrogen fuel.
Kufunika Kwambiri kwa Makampani Opanga Mphamvu za Hydrogen
Monga chonyamulira chachikulu cha mphamvu zoyera, maselo amafuta a haidrojeni amakumana ndi mavuto awiri owongolera magwiridwe antchito ndi kuchepetsa ndalama. Kugwiritsa ntchito ukadaulo wa inline density meter sikuti kumangothetsa mavuto ofunikira pakupanga MEA komanso kumathandizira kukweza ukadaulo m'makampani onse opanga mphamvu za haidrojeni.
Ngati mukufunafunamasensa amkati mwa njiraKuti muchepetse ndalama ndikuwonjezera magwiridwe antchito popanga zinthu zokha, zida zanzeru za Lonnmeter ndi chimodzi mwazosankha zanu zabwino. Kampaniyo ikuperekaZitsanzo 100 zaulere padziko lonse lapansi—Kuchuluka kwake kuli kochepa, choncho chitanipo kanthu mwachangu! Lumikizanani nafe kuti mupeze yankho laulere lopangidwa mwamakonda ndikupempha zitsanzo zaulere.
