Hydrogen zog yog dav paub tias lub zog tshiab tiam tom ntej. Muaj peb yam tseem ceeb cov ntaub ntawv rau hydrogen roj hlwb: catalysts, gas diffusion txheej, thiab proton exchange membranes.
Cov roj diffusion txheej tsis tsuas yog ua haujlwm raws li cov txheej txheem txhawb nqa thiab cov qauv hluav taws xob ruaj khov hauv cov electrode, tab sis kuj muaj ntau yam haujlwm ntawm kev muab cov pa roj, ib qho hluav taws xob, thiab cov dej ntws tawm rau cov tshuaj tiv thaiv electrode. Kev siv cov khoom siv roj diffusion txheej yog qhov zoo los txhim kho tag nrho cov kev ua haujlwm ntawm electrode.
Sintered ntxeem tau hlau yog dav siv nyob rau hauv cov khoom siv hluav taws xob xws li dej electrolysers, unitised regenerative fuel cells (URFCs) li gas diffusion layers (GDLs), thiab roj teeb. Chipnano Advanced Materials tuaj yeem muab cov khoom zoo porous titanium raws li cov roj diffusion txheej, uas muaj cov haujlwm hauv qab no thiab qhov zoo.
-Uniform ntxeem tau qauv, zoo roj permeability;
- Tsawg resistivity, muaj zog electron conductivity;
-Structure Tight thiab tiaj tus, txo kev sib cuag thiab txhim kho hluav taws xob conductivity;
-Muaj qee yam kev siv lub zog, kev nruj thiab yooj yim, uas muaj txiaj ntsig zoo rau kev tsim cov khoom siv hluav taws xob, thiab muab kev ruaj ntseg ntawm cov qauv electrode nyob rau hauv kev ua haujlwm ntev;
- Tsim nyog hydrophilicity / hydrophobic tshuav nyiaj li cas, los tiv thaiv cov dej noo ntau dhau los thaiv qhov pores thiab ua rau txo cov pa permeability;
- Tshuaj stability thiab thermal stability;
-Cov nqi tsim khoom tsawg, kev ua haujlwm siab / tus nqi sib piv.
Cov Ntaub Ntawv Rau Roj Cells
Cov roj hluav taws xob ncaj qha hloov cov tshuaj siv hluav taws xob hauv hydrogen mus rau hluav taws xob, nrog cov dej ntshiab thiab cua sov ua cov khoom lag luam xwb. Hydrogen-powered roj hlwb tsis yog tsuas yog muaj kuab paug xwb, tab sis ib tug ob-rau peb-fold nce nyob rau hauv lub efficiency yuav muaj kev paub thaum piv rau ib txwm combustion technologies. Cov roj hluav taws xob tuaj yeem siv hluav taws xob yuav luag txhua yam khoom siv nqa tau uas ib txwm siv roj teeb. Cov roj ntsha tseem tuaj yeem siv hluav taws xob thauj mus los xws li tsheb, tsheb thauj khoom, tsheb npav, thiab cov nkoj hauv hiav txwv, nrog rau muab lub zog pabcuam rau cov tsheb thauj mus los ib txwm muaj. Hydrogen tuaj yeem ua lub luag haujlwm tseem ceeb hauv lub neej yav tom ntej los ntawm kev hloov cov roj av uas peb tam sim no siv hauv peb lub tsheb thiab cov tsheb thauj khoom.
