Hav nyob ntawd! Raws li tus neeg muag khoom ntawm Graphite Bipolar Phaj, Kuv zoo siab heev los khawb rau hauv lub ntsiab lus ntawm "Dab tsi yog cov qauv ntawm graphite bipolar phaj?"
Cia peb pib nrog cov hauv paus. Graphite bipolar daim hlau ua lub luag haujlwm tseem ceeb hauv cov roj hlwb, uas tau dhau los ua qhov tseem ceeb hauv kev thawb lub zog huv. Lawv zoo li cov neeg tsis paub zoo ntawm lub ntiaj teb cov roj hluav taws xob, ntsiag to ua lawv txoj haujlwm kom tag nrho lub cev ua haujlwm tau zoo.
Cov Qauv Txheej Txheem ntawm Graphite Bipolar Phaj
Ntawm nws cov tub ntxhais, graphite bipolar phaj yog ua los ntawm cov khoom siv graphite. Graphite yog ib yam khoom zoo heev. Nws yog ib daim ntawv ntawm cov pa roj carbon uas muaj qee yam khoom tshwj xeeb. Nws yog cov conductive heev, ob qho tib si hluav taws xob thiab thermally, uas yog qhov tseem ceeb hauv cov roj cell. Hluav taws xob conductivity tso cai rau ntws ntawm electrons, thaum thermal conductivity pab nyob rau hauv dissipating tshav kub generated thaum lub sij hawm cov tshuaj tiv thaiv nyob rau hauv lub roj cell.
Cov graphite siv hauv cov phiaj no feem ntau yog qib siab -, daim ntawv tuab. Qhov ntom ntom no yog qhov tseem ceeb vim tias nws pab tiv thaiv cov pa paug. Hauv cov roj cell, cov roj sib txawv yog siv rau ntawm ob sab ntawm lub phaj bipolar. Piv txwv li, hydrogen feem ntau yog siv rau ntawm ib sab thiab oxygen rau lwm qhov. Yog tias lub phaj tsis tuab txaus, cov pa roj no tuaj yeem nkag mus, uas yuav txo qis cov roj cell thiab tuaj yeem ua rau muaj kev phom sij.
Flow Field Design
Ib qho ntawm qhov tseem ceeb tshaj plaws ntawm cov qauv ntawm graphite bipolar phaj yog cov qauv tsim. Qhov chaw ntws yog ib qho qauv ntawm cov kab uas raug txiav los yog molded rau saum npoo ntawm lub phaj. Cov channel no yog lub luag haujlwm rau kev faib cov roj reactant (xws li hydrogen thiab oxygen) sib npaug thoob plaws ntawm daim nyias nyias - electrode los ua ke (MEA).
Muaj ntau hom kev khiav dej num tsim, thiab txhua tus muaj nws qhov zoo. Piv txwv li, lub parallel flow field tsim muaj ncaj, parallel channels. Nws yog ib qho yooj yim los tsim thiab muab cov roj ntws sib xws hauv ib qho kev taw qhia. Ntawm qhov tod tes, serpentine flow field tsim muaj ntau txoj kev, winding qauv. Qhov kev tsim no tuaj yeem ua kom ntseeg tau cov pa roj zoo dua thiab kev siv ntau dua ntawm cov roj reactant, tab sis nws yuav nyuaj me ntsis thiab raug nqi ntau dua los tsim.
Qhov tob thiab qhov dav ntawm cov channel hauv qhov ntws tawm kuj tau ua tib zoo tsim. Yog tias cov channel loj dhau los yog nqaim dhau, cov roj ntws yuav raug txwv, ua rau kev faib tsis sib xws thiab kev ua haujlwm tsawg. Yog tias lawv tob dhau los yog dav, nws tuaj yeem nkim qhov chaw thiab cov khoom siv, thiab tseem cuam tshuam rau kev ncaj ncees ntawm cov phaj.
Phaj Thickness
Lub thickness ntawm graphite bipolar phaj yog lwm qhov tseem ceeb hauv nws cov qauv. Cov phaj tuab feem ntau muab ntau lub zog siv tshuab. Lawv tuaj yeem tiv taus lub siab thiab cov neeg kho tshuab kev ntxhov siab uas tshwm sim thaum lub sijhawm ua haujlwm ntawm cov roj cell. Txawm li cas los xij, cov phaj tuab kuj ntxiv qhov hnyav thiab ntim rau cov roj cell pawg, uas tej zaum yuav tsis zoo tagnrho, tshwj xeeb tshaj yog nyob rau hauv cov ntawv thov uas qhov chaw thiab qhov hnyav yog nyob ntawm tus nqi, xws li hauv tsheb lossis lub zog hluav taws xob.
Ntawm qhov tod tes, cov phaj nyias nyias yog sib dua thiab sib dua. Lawv tuaj yeem pab txo qis tag nrho qhov loj thiab qhov hnyav ntawm cov roj cell pawg. Tab sis lawv yuav tsum tau ua tib zoo tsim kom ntseeg tau tias lawv tseem muaj zog txaus los ua haujlwm zoo. Cov neeg tsim khoom feem ntau siv cov khoom siv siab heev thiab cov txheej txheem tsim khoom kom sib npaug qhov xav tau ntawm lub zog thiab nyias.
Txheej thiab kho qhov chaw
Ntau cov graphite bipolar daim hlau kuj raug txheej txheej thiab txheej txheem kho deg. Cov kev kho no tuaj yeem ua haujlwm rau ntau lub hom phiaj. Piv txwv li, cov txheej txheem tiv thaiv tuaj yeem siv los tiv thaiv corrosion. Nyob rau hauv ib puag ncig ntawm cov roj hluav taws xob, cov hlau yuav raug rau ntau yam tshuaj thiab electrolytes, uas tuaj yeem ua rau corrosion dhau sijhawm. Ib txheej txheej zoo tuaj yeem ua rau lub neej ntev ntawm lub phaj thiab txhim kho nws txoj kev ntseeg siab.
Kev kho deg kuj tuaj yeem txhim kho cov hydrophobicity ntawm lub phaj. Hydrophobicity txhais tau hais tias muaj peev xwm los tua cov dej. Hauv cov roj cell, dej yog tsim los ntawm - cov khoom ntawm cov tshuaj tiv thaiv. Yog tias cov dej tsis raug tshem tawm kom raug, nws tuaj yeem ua rau dej ntws thiab thaiv cov roj ntws, txo qhov kev ua haujlwm ntawm cov roj cell. Ib qho chaw hydrophobic pab ua kom cov channel qhuav thiab tso cai rau cov roj ntws zoo dua.
