Cov txheej txheem thauj khoom ntxeem tau (PTL) yog qhov tseem ceeb hauv cov khoom siv hluav taws xob hauv cov khoom siv hluav taws xob (PEM) rau cov khoom siv hydrogen. Lawv muab ib txoj hauv kev rau kev thauj roj, kev faib hluav taws xob, thiab hloov hluav taws xob ntawm cov electrodes thiab daim nyias nyias.
Hauv PEM dej electrolysis system, PTL tau muab tso rau ntawm sab anode ntawm daim nyias nyias electrode los ua ke (MEA) los muab kev sib txuas thiab ntxeem tau rau hydrogen gas evolution. Cov roj hydrogen uas ua rau ntawm lub anode tuaj yeem kis tau los ntawm PTL thiab muab khaws cia rau saum lub cell electrolysis.
Cov khaubncaws sab nraud povtseg (PTLs) ua lub luag haujlwm tseem ceeb hauv kev tsim cov hydrogen los ntawm cov khoom siv hluav taws xob hloov pauv (PEM) dej electrolysis. PTLs muab ib txoj hauv kev rau kev thauj cov pa roj, kev faib hluav taws xob, thiab kev hloov hluav taws xob ntawm cov electrodes thiab daim nyias nyias, ua rau lawv yog ib qho tseem ceeb hauv cov txheej txheem.
Ib qho khoom siv nrov siv rau PTLs yog sintered ntxeem tau titanium phaj. Cov khoom siv no muaj cov khoom zoo heev, nrog rau cov hluav taws xob siab, kev tiv thaiv corrosion, thiab lub zog txhua yam. Cov qauv sintered ntxeem tau kuj muab thaj chaw loj rau kev siv roj diffusion thiab electrolyte faib, thaum txo qis kev thauj khoom loj.
1
Zoo heev corrosion kuj
Sintered ntxeem tau titanium phaj PTLs yog tshwj xeeb tshaj yog haum rau hydrogen ntau lawm vim lawv zoo heev corrosion kuj, txawm nyob rau hauv hnyav tshuaj ib puag ncig. Qhov no ua rau lawv zoo tagnrho rau siv nyob rau hauv acidic PEM electrolysis hlwb, qhov uas lawv muaj peev xwm muab kev ruaj ntseg mus sij hawm ntev thiab kev ntseeg tau.
2
High hluav taws xob conductivity
Lub siab hluav taws xob conductivity ntawm sintered ntxeem tau titanium phaj PTLs kuj ua kom muaj hluav taws xob hloov pauv ntawm cov electrodes thiab daim nyias nyias. Qhov no ua rau txo qis ntawm lub zog xav tau los tsim cov hydrogen, uas ua rau muaj txiaj ntsig zoo dua.
3
Muaj cov qauv ntxeem tau
Tsis tas li ntawd, cov qauv ntxeem tau ntawm sintered ntxeem tau titanium phaj PTLs ua rau kom muaj roj diffusion, uas ua rau kev txhim kho kev thauj mus los thiab cov txheej txheem electrolysis zoo dua. Qhov no tuaj yeem ua rau ntau dua hydrogen ntau lawm thiab txhim kho kev ua haujlwm.
Hauv kev xaus, sintered ntxeem tau titanium phaj PTLs yog qhov tseem ceeb hauv kev tsim cov hydrogen los ntawm PEM dej electrolysis. Lawv cov khoom tshwj xeeb ua rau lawv tshwj xeeb zoo rau cov tshuaj lom neeg hnyav ntawm cov kua qaub PEM electrolysis hlwb, muab kev ruaj ntseg mus ntev thiab kev ntseeg siab. Lawv kuj muab cov roj diffusion zoo, hloov hluav taws xob, thiab tiv thaiv corrosion, ua rau lawv xaiv zoo tshaj plaws rau cov khoom siv hluav taws xob zoo thiab raug nqi.
