Sintered ntxeem tau titanium feem ntau yog siv los ua cov khoom siv anode hauv PEM electrolyzer. Nws txoj haujlwm yog los qhia txog tam sim no rau hauv electrolyte los txhawb kev txo cov tshuaj tiv thaiv ntawm hydrogen ions (H ntxiv) thiab dej molecules (H2O) los tsim hydrogen (H2).
Tshwj xeeb, cov anode hauv PEM electrolyzer yog ua los ntawm sintered ntxeem tau titanium, uas yog coated nrog ib tug catalyst, feem ntau platinum (Pt), hlau-cobalt (Feco), thiab lwm yam. Thaum ib tug hluav taws xob tam sim no siv rau lub electrolyzer, lub nto catalyst. ntawm sintered ntxeem tau titanium tuaj yeem ua kom txo qis cov tshuaj tiv thaiv ntawm hydrogen ions (H ntxiv) thiab dej molecules (H2O), tsim cov roj hydrogen (H2) thiab electrons (e-). Nyob rau tib lub sijhawm, cov qauv ntxeem tau ntawm sintered ntxeem tau titanium tuaj yeem ua rau thaj chaw sib cuag thiab catalytic efficiency ntawm cov tshuaj tiv thaiv, yog li ua kom cov khoom siv hluav taws xob thiab cov nqi ntawm hydrogen ntau lawm.
Tsis tas li ntawd, sintered ntxeem tau titanium tseem tuaj yeem ua lub luag haujlwm hauv kev lim dej thiab txhawb nqa cov khoom siv electrolyte, ua kom cov dej ntws ntawm cov electrolyte thiab kev ruaj ntseg ntawm cov txheej txheem electrolysis.
Piv nrog rau lwm cov ntaub ntawv, sintered ntxeem tau titanium muaj cov hauv qab no zoo:
1. Muab piv nrog cov hlau zoo xws li platinum, tus nqi ntawm sintering ntxeem tau titanium yog tsawg, thiab tus nqi ntawm kev npaj yog tsawg.
2. Piv nrog cov ntaub ntawv carbon, sintered ntxeem tau titanium muaj ntau dua hluav taws xob conductivity thiab txhua yam muaj zog, uas yuav ua tau raws li qhov yuav tsum tau ntawm ib co high-flow electrolyzers.
3. Piv nrog rau lwm cov ntaub ntawv hlau, sintered ntxeem tau titanium muaj ib tug ntau dua qhov chaw nto, uas yuav txhim kho qhov chaw tiv tauj thiab catalytic efficiency ntawm cov tshuaj tiv thaiv.
Zuag qhia tag nrho, sintered ntxeem tau titanium plays lub luag haujlwm tseem ceeb hauv PEM electrolyzers thiab yog cov khoom siv feem ntau siv anode. Los ntawm nws cov khoom siv hluav taws xob zoo heev, thaj chaw tshwj xeeb ntawm qhov chaw, thiab kev ruaj ntseg tshuaj zoo, nws tuaj yeem txhawb cov tshuaj tiv thaiv electrolysis ntawm dej thiab txhim kho kev ua haujlwm thiab hydrogen ntau lawm ntawm electrolyzer.
