Muchikamu chekugadzira mafuta ehydrogen mafuta, iyo Membrane Electrode Assembly (MEA) inoshanda sechinhu chakakosha chekushandura simba, ichinyatso tarisa kushanda kwebhatiri uye hupenyu hurefu. Nhanho yekutanga yekugadzirwa kweMEA kuburikidza nekupisa kupisa ndiko kukonzeresa slurry musanganiswa-danho rakakosha rinopesvedzera yekupedzisira chigadzirwa mhando. Kuita uku kunoda kusanganiswa chaiko kwePt-C catalysts, solvents, uye binders kuti iite musanganiswa wakapararira wakagadzikana wakafanana.
Kurwisana kwechinyakare kusanganisa kunyatso kudzora chikamu chechikamu chimwe nechimwe uye nyika yekupararira, zvichitungamira kune nyaya dzakaita sekunge kusaenzana kwekupfeka uye kuderedzwa kwekuita kwekuita mumatanho anotevera. Kushandiswa kweinline density metres inopa mhinduro yekubudirira, inogonesa kurongeka chaiko kwechikamu cheratidzo uye kuparadzira mhedzisiro kuburikidza nechaiyo-nguva yekutarisa ye slurry density shanduko.
Lonnmeter Group, inotungamira kugadzira uye mutengesi weinline density metres, yakazvipira makumi emakore kupa mhinduro dzehunyanzvi kune vatengi pasi rese. Mhinduro idzi dzakabatsira akawanda mafekitori emaindasitiri, zvidyarwa zvemagetsi, uye mabhizinesi esimbi kudzikisa mutengo nekuvandudza kugona.
Basa Rakakosha reSlurry Kusanganisa
Kuita kwehydrogen mafuta cell MEAs zvakanyanya kunoenderana nekufanana uye kugadzikana kwezvinokonzeresa slurries. Semuenzaniso, anode slurries inoda 15% Pt-C catalyst yakafanana yakaparadzirwa mumusanganiswa wakasanganiswa we40% deionized mvura, 40% methanol, uye 5% ionomer solution; cathode slurries inoda huwandu hwepamusoro hwecatalyst (20%) uye binder (10%). Iyi chaiyo reshiyo haingokanganisa slurry's yemuviri zvimiro asi zvakare inopesvedzera zvakananga kugoverwa kwecatalytic inoshanda masaiti uye proton conductivity.
Kudzora kusakwana kwe density kunogona kukonzera catalyst agglomeration kana sedimentation, zvichikonzera kusaenzana kukora kweiyo coated catalyst uye kunyangwe kuita kwebhatiri kwese. Semuyenzaniso, kuwanda kwepamusoro kunogona kuratidza yakawandisa catalyst kana solvent evaporation, kuwedzera slurry viscosity uye kukonzera "orange peel" kana "pinhole" kukanganisa panguva yekupfeka; density yakaderera inogona kuratidza kusakwana catalyst, kutadza kupa yakakwana reaction sites uye kuderedza kushanda kwebhatiri.
Kuganhurirwa kweTraditional Slurry Density Control
Traditional catalyst slurry mixing inotsamira pakuyerwa kwemaoko uye kuyedza pasina Indaneti mupuraimari. Iyi nzira inosarira kumashure-chaiyo-nguva maitiro zvakanyanya-kuwana bvunzo mhinduro kubva kusampling kazhinji kunotora 15-30 maminetsi, panguva iyo slurry inogona kunge yapinda mune inotevera maitiro, zvichitungamira kune yakakura kudzoreredza tsvina.
Manual mashandiro anonetsekana kuona nanoscale catalyst particle agglomeration. Pamusoro pezvo, zvinhu zvakaita sekuchinja kwetembiricha uye kunyungudika kwekunyungudika kunokonzeresa kushanduka kwehudhinha mumaslurries, ayo maitiro echinyakare haakwanise kubhadhara munguva chaiyo, zvichiwedzera kuwedzera kusagadzikana kwehunhu.
Kushanda Principle uye Technical Advantages
Kugadzirisa matambudziko aya, mainjiniya eLonnmeter akagadzira inline density metres zvichibva paiyo Coriolis simba musimboti, iyo inoyera fluid vibration frequency kuti iwane chaiyo-nguva density data nechaiyo inosvika ± 0.001 g/cm³. Mukusanganiswa kwe slurry yehydrogen mafuta sero, aya epamusoro-chaiyo ekutarisa maturusi anogona kuisirwa panobuda matangi ekusanganisa kana mapaipi ekutenderera kuti arambe achiunganidza density uye tembiricha data, ine muripo algorithms inobvisa kukanganisa kwekushisa pa density.
Beyond Coriolis density metres, Lonnmeter yakagadzirawo mamwe inline density metres senge tuning forogo density metres uye ultrasonic density metres kuti ipe hungwaru density yekutarisa ma sensors emamiriro akasiyana ekushanda. Paunenge uchiona kuti cathode slurry density inodarika kukosha kwechinangwa, iyo system inongoverengera kutsauka uye inowedzera huwandu hwakakodzera hwesolvent kuburikidza nepombi yemamita; kana density yakanyanya kuderera, pre-dispersed catalyst amai doro rinowedzerwa. Iyi ine simba loop control haingogadzirise kutsauka kwefomula chete asiwo inofanotaura zvingangoitika kuburikidza nenhoroondo yekuongorora data. Kana density inoshanduka ikadarika zvikumbaridzo, sisitimu inokonzeresa maalarm kuti akurudzire kupararira kusiri-uniform kana kupatsanurwa kwechikamu, kudzivirira tsaona dzemhando yepamusoro.
Mibairo yeContinuous Density Monitoring
Enhanced Fuel Cell Kugadzikana
Lonnmeter inline density metres yakabatsira vagadziri vemafuta emafuta kuti vakwanise kubudirira mukusanganisa kusanganisa. Kuburikidza nekutarisa-nguva chaiyo uye kutonga kwakangwara, slurry density kuchinjika siyana dzakaderedzwa zvakanyanya kubva ± 0.03 g/cm³ kusvika ± 0.001 g/cm³. Kuvandudzwa uku kunosimudzira kuenderana kwechigadzirwa uye kugadzikana kwekuita, kuwedzera mafuta emagetsi emagetsi eimwe bhizinesi ne15%.
Yakanyanya Kuvandudza Kubudirira Kwekugadzira
Nguva yekugadzirwa kwebatch imwe yakapfupikiswa, nekuchengetedza kwepagore kunodarika $300,000 mumutengo wezvinhu uye rework. Uyezve, kushandiswa kwemainline density metres kwakagonesa maitiro ese. Yakabatanidzwa neDCS masisitimu, inogonesa kutonga kwakazara kwedhijitari kubva paformula manejimendi kusvika pakutarisisa kwemhando, vachiisa hwaro hwehukuru hwekugadzira mafuta ehydrogen sero.
Yakakosha Kukosha kweHydrogen Energy Indasitiri
Semutakuri wepakati wesimba rakachena, hydrogen mafuta maseru anotarisana nematambudziko maviri ekuvandudza mashandiro uye kuderedza mitengo. Iko kushandiswa kweiyo inline density meter tekinoroji haingogadzirise matambudziko akakosha mukugadzirwa kweMEA asi zvakare inotyaira kukwidziridzwa kwetekinoroji mukati meketani yese yeindasitiri yesimba rehydrogen.
Kana uri kutsvagainline process sensorskuderedza mutengo uye kuwedzera kushanda zvakanaka mukugadzira otomatiki, Lonnmeter yakangwara chiridzwa ndeimwe yesarudzo dzako dzakanakisa. Iyo kambani iri kupa100 emahara samples pasi rese-huwandu hushoma, saka ita nekukurumidza! Bata isu kuti titore yemahara yakagadziridzwa mhinduro uye nyorera yemahara samples.
