Cov Txheej Txheem Thauj Pob Txhaum (PTL) yog ib qho tseem ceeb ntawm PEM electrolyzer, feem ntau nyob nruab nrab ntawm Gas Diffusion Layer (GDL) thiab cov electrode.
Nws ua lub luag haujlwm tseem ceeb hauv kev ua kom muaj txiaj ntsig zoo ntawm kev thauj khoom ntawm cov khoom siv hluav taws xob thiab cov khoom siv roj, tswj cov dej hauv electrolyzer, tswj kev pom kev siab thiab cov pa xa hluav taws xob, thiab muab kev txhawb zog rau cov khoom siv electrode.
Thaum xaiv PTL, cov ntsiab lus tseem ceeb yuav tsum xav txog suav nrog nws qhov porosity, thickness, conductivity, mechanical zog, thiab tshuaj stability.
Gas Diffusion Layer (GDL) thiab Porous Transport Layer (PTL) yog ob qho tib si cov khoom ntxeem tau siv hauv cov roj hlwb thiab cov khoom siv hluav taws xob, tab sis lawv muaj cov haujlwm sib txawv thiab cov qauv.
GDL yog ib txheej nyias, ntxeem tau nyob nruab nrab ntawm cov electrode thiab reactant gas flow field nyob rau hauv roj hlwb los yog electrolyzers. Nws lub hom phiaj tseem ceeb yog thauj cov roj reactant mus rau qhov chaw electrode thiab tshem tawm cov dej ntau dhau uas ua rau cov tshuaj tiv thaiv electrochemical. GDL kuj muab hluav taws xob conductivity ntawm cov electrode thiab cov khoom siv tam sim no, uas sau cov hluav taws xob tam sim no los ntawm cov tshuaj tiv thaiv.
Hauv qhov sib piv, PTL yog txheej ntxeem tau siv los sib faib cov roj reactant thoob plaws hauv cov hluav taws xob hauv cov roj hlwb lossis cov hluav taws xob electrolyzers. PTL kuj tseem tuaj yeem ua qhov cuam tshuam los tiv thaiv dej nyab ntawm electrode los ntawm cov roj reactant ntau dhau thiab tswj cov dej thauj mus deb ntawm electrode.
Txawm hais tias PTLs thiab GDLs yog ob qho tib si ua los ntawm cov pa roj carbon monoxide xws li cov ntawv carbon, Porous titanium, lossis titanium fiber, cov khoom siv tshwj xeeb thiab cov qauv ntawm PTL thiab GDL tuaj yeem cuam tshuam rau kev ua haujlwm ntawm cov roj hlwb thiab electrolyzers. Kev xaiv ntawm cov ntaub ntawv yuav nyob ntawm seb lub cuab yeej yuav tsum tau ua, xws li cov roj kub kub uas siv Ti-raws li cov ntaub ntawv rau PTL thiab GDL kom tiv taus qhov kub thiab txias.
Hauv cov ntsiab lus, cov qauv thiab kev ua haujlwm ntawm PTLs thiab GDLs txawv, tab sis ob qho tib si cov ntaub ntawv yog qhov tseem ceeb rau kev ua haujlwm ntawm cov roj cell thiab electrolyzer. Cov ntaub ntawv siv rau PTLs thiab GDLs tuaj yeem sib txawv raws li cov khoom yuav tsum tau ua, thiab cov ntaub ntawv Ti-raws li feem ntau yog siv vim lawv cov conductivity siab thiab compatibility nrog catalyst cov ntaub ntawv.
