4-qhov porcelain sawb yog cov khoom siv ua haujlwm ceramic nrog cov qauv ntxeem tau tshwj xeeb, tsim nrog plaub qhov sib npaug los ntawm -microchannels kom muaj txiaj ntsig zoo ntawm cov pa roj thiab kev sib cais. Nws cov khoom siv yog feem ntau ntxeem tau alumina los yog mullite, xaiv rau lawv ua ke ntawm porosity, mechanical zog, thiab siab - kub stability, raws li teev nyob rau hauv nws cov qauv khoom. Cov txheej txheem tsim khoom suav nrog precision extrusion molding (los tsim plaub lub microchannels) ua raws li siab -kub sintering-cov kauj ruam sintering no tsis tsuas yog txhim kho cov khoom ntawm cov qauv kev ncaj ncees tab sis kuj tswj kev tsim ntawm nws cov ntxeem tau network, kom ntseeg tau tias kev ua haujlwm zoo ib yam ntawm cov khoom siv.
Cov yam ntxwv tseem ceeb ntawm cov khoom lag luam suav nrog qhov nruab nrab qhov pore loj (xws li 5-}50 microns, haum rau daim ntawv thov xav tau), porosity ntawm kwv yees li 40% (kom sib npaug roj permeability thiab txhua yam muaj zog), thiab lub zog compressive tsis pub tsawg dua 50 MPa (kom tiv taus kev sib dhos thiab kev ua haujlwm siab). Tsis tas li ntawd, nws nthuav tawm zoo heev - kub stability thiab tshuaj inertness, tswj kev ua tau zoo txawm nyob rau hauv ib puag ncig mus txog 800℃- tseem ceeb heev rau nws thawj daim ntawv thov nyob rau hauv cov khoom oxide roj hlwb (SOFCs).
Nyob rau hauv SOFC systems, 4-qhov porcelain sawb ua hauj lwm raws li ib tug dual-function Cheebtsam: nws ua raws li ib tug gas diffusion txhawb kom ntseeg tau tias ib yam ntawm cov roj gas (xws li hydrogen) thiab oxidant (xws li huab cua) nyob rau hauv lub cell nto, thiab raws li ib tug cais sawb los tiv thaiv tus ntoo khaub lig- paug ntawm ob gases. Ntawm SOFC qhov kev khiav hauj lwm kub ntawm 800 degree, cov qauv ntxeem tau ntawm cov khoom txhim kho ionic conductivity nyob rau hauv lub cell, ncaj qha mus rau ib tug nce nyob rau hauv ib tug -cell zog ceev mus rau 1.2 W / cm²- ib qho tseem ceeb kev txhim kho rau boosting tag nrho cov efficiency ntawm SOFC pawg. Tsis zoo li cov khoom siv uas tsis muaj qhov ntxeem tau lossis cov txheej txheem tsis zoo, 4-qhov porcelain sawb ua kom cov roj ntws zoo sib xws thiab tsis muaj zog, txo qis zog thiab txuas ntxiv roj cell lub neej kev pab cuam. Rau cov chaw tsim khoom ntawm cov khoom siv hluav taws xob huv, cov khoom lag luam yog cov khoom siv tseem ceeb uas txhim kho kev ua haujlwm thiab kev ntseeg siab ntawm SOFC systems, txhawb kev nce qib ntawm cov thev naus laus zis thev naus laus zis.
