Muchikamu chekugadzira hydrogen fuel cell, Membrane Electrode Assembly (MEA) inoshanda sechikamu chikuru chekushandura simba, ichinyatsoona kushanda kwebhatiri uye hupenyu hwaro. Danho rekutanga rekugadzira MEA kuburikidza nekupisa kutapurirana kusanganisa catalyst slurry—danho rakakosha rinopesvedzera kunaka kwechigadzirwa chekupedzisira. Maitiro aya anoda kusanganisa kwakanyatsojeka Pt-C catalysts, solvents, uye binders kuti vagadzire musanganiswa wakasimba wakapararira zvakaenzana.
Kusanganisa kwechinyakare kunonetsa kudzora huwandu hwechikamu chimwe nechimwe uye mamiriro ekupararira, zvichikonzera matambudziko akadai sekusiyana kwemavara uye kudzikira kwemabasa ekugadzirisa zvinhu mumatanho anotevera.mamita ehuwandu hwemukati inopa mhinduro yekubudirira, ichigonesa kudzora kwakarurama kwezvikamu zvezvikamu uye mhedzisiro yekupararira kuburikidza nekutarisa nguva chaiyo kwekuchinja kwehuwandu hweslurry.
Lonnmeter Group, kambani inotungamira mukugadzira uye mutengesi wemamita ekudzikisa huwandu hwemagetsi, yakazvipira makumi emakore kupa mhinduro dzehunyanzvi kune vatengi pasi rese. Mhinduro idzi dzakabatsira mafekitori mazhinji emaindasitiri, mafekitori emagetsi, uye mabhizinesi esimbi kuderedza mitengo uye kuvandudza mashandiro.
Basa Rakakosha reKusanganisa Slurry
Kushanda kwehydrogen fuel cell MEAs kunoenderana zvikuru nekufanana uye kugadzikana kwecatalyst slurries. Semuenzaniso, anode slurries inoda 15% Pt-C catalyst yakapararira zvakaenzana mumusanganiswa we40% deionized water, 40% methanol, uye 5% ionomer solution; cathode slurries inoda huwandu hwakakura hwecatalyst (20%) uye binder (10%). Iyi chaiyo ratio haingokanganisi chete hunhu hweslurry asiwo inokanganisa zvakananga kupararira kwenzvimbo dzinoshanda dzecatalytic uye proton conductivity.
Kudzora huwandu husina kunaka kunogona kukonzera kuungana kwe catalyst kana sedimentation, zvichikonzera ukobvu husina kuenzana hwe catalyst yakaputirwa uye kunyange kushanda kwebhatiri rese. Semuenzaniso, huwandu hwakawanda hunogona kuratidza kuwanda kwe catalyst kana solvent evaporation, kuwedzera slurry viscosity uye kukonzera "orange peel" kana "pinhole" defects panguva ye coating; huwandu hushoma hunogona kuratidza kusakwana kwe catalyst, kutadza kupa nzvimbo dzakakwana dze reaction uye kuderedza kushanda kwebhatiri.
Kuganhurirwa kweKudzora Kuwanda kweSlurry Yechinyakare
Kusanganisa slurry yechinyakare kunobva pakuyera nemaoko uye kuyedzwa pasina kushandisa makemikari mukutanga. Maitiro aya ari kumashure zvakanyanya nemaitiro enguva chaiyo—kuwana mhedzisiro yebvunzo kubva mukuongororwa kunowanzotora maminetsi gumi nemashanu kusvika makumi matatu, panguva iyo slurry ingave yapinda mumaitiro anotevera, zvichikonzera kurasikirwa kukuru kwekugadzirisa patsva.
Kushanda nemaoko kunonetsa kuona nanoscale catalyst particle agglomeration. Pamusoro pezvo, zvinhu zvakaita sekuchinja kwetembiricha uye evaporation ye solvent zvinokonzera dynamic density kushanduka-shanduka mumaslurry, izvo maitiro echinyakare asingakwanise kutsiva munguva chaiyo, zvichiwedzera njodzi dzekusagadzikana kwemhando.
Nheyo yekushanda uye mabhenefiti ehunyanzvi
Kuti vagadzirise matambudziko aya, mainjiniya eLonnmeter vakagadzira mita dzehuwandu hwemvura dzakagadzirwa zvichibva paCoriolis force principle, iyo inoyera frequency yekudengenyeka kwemvura kuti iwane data rehuwandu hwemvura panguva chaiyo nekunyatsojeka kusvika ku±0.001 g/cm³. Mukusanganisa hydrogen fuel cell, zvishandiso izvi zvekutarisa zvine hungwaru zvinogona kuiswa panzvimbo inobuda matangi ekusanganisa kana mapaipi ekutenderera kuti zvirambe zvichiunganidza data rehuwandu hwemvura nekupisa, nemaitiro ekugadzirisa anobvisa kukanganisa kwekupisa pahuwandu hwemvura.
Kupfuura Coriolis density meters, Lonnmeter yakagadzirawo mamwe ma inline density metres akadai se tuning fork density meters uye ultrasonic density meters kuti ipe intelligent density monitoring sensors yemamiriro akasiyana ekushanda. Kana ichiona kuti cathode slurry density inodarika target value, system inoverenga otomatiki deviation uye inowedzera huwandu hwakakodzera hwe solvent kuburikidza ne metering pombi; kana density yakaderera zvakanyanya, pre-dispersed catalyst mother liquor inowedzerwa. Iyi dynamic loop control haingogadzirisi chete formula deviations asiwo inofanotaura matambudziko anogona kuitika kuburikidza ne nartic data analysis. Kana density fluctuations ikadarika thresholds, system inokonzeresa alarm kuti ikurumidze potential non-uniform dispersion kana phase separation, kudzivirira njodzi dzemhando ye batch mberi.
Mhedzisiro yeKutarisa Kuwanda Kwevanhu Nguva Dzose
Kugadzikana Kwemasero Emafuta Kwakawedzerwa
Mamita eLonnmeter inline density akabatsira vagadziri vemafuel cell kuti vawane budiriro huru mukusanganisa macatalyst slurry. Kuburikidza nekutarisa kwenguva chaiyo uye kutonga kwakangwara, kushanduka kwehuwandu hwemafuel density kwaderedzwa zvakanyanya kubva pa ±0.03 g/cm³ kusvika ±0.001 g/cm³. Kuvandudzwa uku kunosimudzira zvakananga kugadzikana kwechigadzirwa uye kugadzikana kwekushanda, zvichiwedzera huwandu hwesimba remafuel cell ebhizinesi rimwe ne15%.
Kubudirira Kwakanyanya Kuvandudzwa Kwekugadzira
Nguva yekugadzira zvinhu zvega yapfupikiswa, nemari inochengetedzwa pagore inodarika $300,000 yezvinhu uye yekugadzirisa patsva. Uyezve, kushandiswa kwemamita ekudzikisa huwandu hwezvinhu kwakavandudza maitiro ese. Yakabatanidzwa nemasisitimu eDCS, anogonesa manejimendi yakazara kubva pakugadzirisa fomura kusvika pakutevedza mhando, zvichiisa hwaro hwekugadzirwa kwemaseru ehydrogen fuel cell akawanda.
Kukosha Kwakakura kweIndasitiri yeSimba reHydrogen
Senzira huru yekutakura simba rakachena, masero emafuta ehydrogen anotarisana nematambudziko maviri ekuvandudza mashandiro uye kuderedza mitengo. Kushandiswa kwetekinoroji ye inline density meter hakungogadzirisi matambudziko makuru ekugadzira MEA chete asiwo kunosimudzira kuvandudzwa kwetekinoroji muchikamu chose cheindasitiri yesimba rehydrogen.
Kana uri kutsvagamasensa ekugadzirisa ari mukatiKuderedza mitengo uye kuwedzera kushanda zvakanaka mukugadzira otomatiki, Lonnmeter intelligent instrumentation ndeimwe yesarudzo dzako dzakanakisa. Kambani iri kupaSampuli dzemahara zana pasi rese—huwandu hwakaganhurirwa, saka ita nekukurumidza! Taura nesu kuti uwane mhinduro yakasarudzika yemahara uye kunyorera sampuro dzemahara.
