Porous titanium daim hlau los ntawm TOPTITECH yog ib qho zoo heev thiab ultra-thin hloov txheej uas yuav siv tau raws li ib tug anode diffusion media nyob rau hauv txheem PEM electrolyzers. Cov hlau los yog titanium-raws li electrodes no tshwj xeeb tsim los siv rau hauv cov dej ntws thiab cov ntaub ntawv sib txawv, tshwj xeeb tshaj yog nyob rau sab oxygen (anode), qhov chaw thauj khoom loj dua thiab cov hneev taw me yog qhov tseem ceeb.
Vim lawv qhov kev ua tau zoo tshwj xeeb thiab kev ua haujlwm zoo, titanium daim hlau ntxeem tau los ntawm TOPTITECH tau txais kev nyiam ntawm cov neeg siv cov qauv PEM electrolyzers.
Vim li cas ho tsis muaj carbon-baed gas diffusion txheej?
Muaj ob peb lub laj thawj vim li cas carbon-based gas diffusion txheej (GDLs) feem ntau tsis siv ntawm anode ntawm electrolyzers:
Corrosion: Cov ntaub ntawv carbon tuaj yeem ua rau corrosion hauv acidic lossis alkaline ib puag ncig, uas feem ntau siv hauv electrolyzers. Qhov no tuaj yeem ua rau GDL degradation dhau sijhawm, txo nws cov txiaj ntsig thiab ua rau muaj kev puas tsuaj rau cov khoom siv hluav taws xob electrolyzer.
Gas crossover: Carbon-based GDLs tuaj yeem permeable rau hydrogen roj ntau dua li lwm cov ntaub ntawv, uas tuaj yeem ua rau cov roj sib txawv ntawm cov anode thiab cathode compartments. Qhov no tuaj yeem txo qhov ua haujlwm ntawm electrolyzer thiab ua rau muaj teeb meem kev nyab xeeb.
Contamination: Cov ntaub ntawv carbon kuj tuaj yeem ua rau muaj kab mob, tshwj xeeb tshaj yog los ntawm cov organic tebchaw. Qhov no tuaj yeem ua rau txo qis kev ua haujlwm thiab lub neej ntev ntawm GDL, nrog rau kev puas tsuaj rau lwm yam khoom ntawm electrolyzer.
Kev tswj cov cua sov: Cov tshuab hluav taws xob tuaj yeem tsim cov cua kub tseem ceeb thaum lub sijhawm ua haujlwm, thiab cov pa roj carbon-based GDLs yuav tsis muaj txiaj ntsig zoo ntawm cov cua kub dissipating li lwm cov ntaub ntawv. Qhov no tuaj yeem ua rau qhov kub tsis sib xws hauv cov electrolyzer, uas tuaj yeem txo qhov ua haujlwm tau zoo thiab ua rau muaj kev puas tsuaj.
Zuag qhia tag nrho, thaum carbon-based GDLs tuaj yeem tsim nyog rau qee qhov kev siv, lawv tsis yog feem ntau siv ntawm cov anode ntawm electrolyzers vim muaj peev xwm rau corrosion, roj crossover, kev sib kis, thiab cov teeb meem kev tswj cua sov. Lwm cov ntaub ntawv, xws li hlau lossis polymer-based GDLs, feem ntau nyiam rau cov ntawv thov no.
