10um Titanium Anode PTL GDL Rau PEM / PEMFC

PEM thiab PEMFC: Nkag siab qhov txawv qhov tseem ceeb

PEM stands rau Proton Exchange Membrane, thaum PEMFC sawv rau Proton Exchange Membrane Roj Cell.

Proton Exchange Membrane yog ib zaj duab xis nyias uas tuaj yeem hloov hydrogen thiab oxygen rau hauv hluav taws xob. Hauv Proton Exchange Membrane Roj Cell, hydrogen tau tawg mus rau hauv protons thiab electrons, nrog cov protons dhau los ntawm daim nyias nyias thiab cov electrons ntws los ntawm ib qho hluav taws xob sab nraud los tsim hluav taws xob.

Yog li ntawd, PEM yog ib daim nyias nyias, thaum PEMFC yog roj cell raws li daim nyias nyias. Ib qho PEMFC feem ntau muaj cov khoom sib pauv hloov pauv, ib qho anode, cathode, thiab electrolyte, uas ua haujlwm ua ke los hloov cov hydrogen rau hauv hluav taws xob thaum tsim dej thiab cua sov ua cov khoom lag luam.

Yog li, PEM thiab PEMFC yog ob lub ntsiab lus sib txawv, nrog PEM yog ib daim nyias nyias thiab PEMFC yog roj cell raws li daim nyias nyias.

PTL in PEM

PTL yog hais txog cov yeeb yaj kiab ua yeeb yaj kiab, tseem hu ua "Electrode Flow Field Layer," ntawm cov txheej txheem roj thiab cov txheej txheem hluav taws xob ntawm Proton Exchange Membrane Fuel Cell (PEMFC).

PTL feem ntau yog ua los ntawm 10 um ntxeem tau titanium phaj los yog 20 um titanium fiber ntau xav thiab yog siv los txhim kho cov adhesion ntawm cov electrode txheej thiab cov roj diffusion txheej, thiab muab ib txoj kev rau electron conduction. Nws kuj tseem pab txhawm rau tawg hydrogen thiab oxygen thiab txhawb nqa txawm tias muaj kev cuam tshuam, yog li txhim kho kev ua haujlwm thiab ruaj khov ntawm PEMFC.

GDL in PEMFC

GDL yog hais txog Gas Diffusion Layer hauv Proton Exchange Membrane Roj Cells (PEMFC).

GDL feem ntau yog ua los ntawm cov porous titanium phaj nrog lub pore loj ntawm 10 um lossis titanium xav tau ntawm 20 um kom faib cov reactants sib npaug thiab ua tau zoo. Nws yog siv los faib cov hydrogen thiab oxygen mus rau txheej txheej electrode thiab tshem tawm cov dej thiab cua sov los ntawm cov tshuaj tiv thaiv. Nws kuj tseem ua haujlwm raws li cov khoom siv hluav taws xob, tso cai rau cov hluav taws xob ntws los ntawm tag nrho cov electrode txheej thiab mus rau hauv Circuit Court.

Hauv PEMFC, GDL nyob nruab nrab ntawm cov cathode thiab anode thiab ua lub luag haujlwm hauv kev faib cov hydrogen thiab oxygen mus rau txheej electrode thaum pab tshem tawm cov dej thiab cua sov. Nws kuj tseem muab txoj hauv kev coj ua, tso cai rau cov khoom siv hluav taws xob ntws mus rau hauv cov txheej txheem electrode, tsim hluav taws xob.

Hauv cov ntsiab lus, titanium anode PTL GDL yog ib qho tseem ceeb ntawm cov roj cell. Lub titanium anode ua lub electrode qhov twg cov roj yog oxidized, thaum lub PTL thiab GDL pab kev thauj cov reactants mus rau lub catalyst txheej thiab pab faib cov reactants tusyees nyob rau hauv lub cell. Ua ke, cov khoom siv no ua haujlwm kom muaj txiaj ntsig thiab txhim khu kev ntseeg ntawm cov roj rau hauv hluav taws xob.

Khoom nta

Durability

Titanium yog cov khoom siv muaj zog thiab ruaj khov uas tuaj yeem tiv taus ntau yam ntawm qhov kub thiab txias. Qhov no ua rau nws yog ib qho khoom siv zoo tshaj plaws rau kev siv roj hlwb, qhov twg cov khoom yuav tsum muaj peev xwm tiv taus cov kev ntxhov siab ntawm kev ua haujlwm ntev ntev.

 

Corrosion kuj

Titanium yog cov resistant rau corrosion, uas ua rau nws yog ib qho zoo tagnrho cov ntaub ntawv rau siv nyob rau hauv hnyav ib puag ncig xws li roj hlwb. Lub titanium anode PTL GDL yog tag nrho raug rau acidic thiab alkaline tej yam kev mob, thiab kev siv ntawm titanium xyuas kom meej tias cov khoom no yuav tsis corrode los yog degrade lub sij hawm.

 

Compatibility nrog lwm cov ntaub ntawv

Titanium yog sib xws nrog ntau yam ntawm lwm yam khoom siv hauv roj hlwb, xws li polymer electrolyte membranes thiab catalysts. Qhov no ua rau nws yooj yim rau kev koom ua ke rau hauv cov qauv roj hluav taws xob uas twb muaj lawm thiab ua kom ntseeg tau tias cov roj hluav taws xob yuav ua haujlwm tau zoo nyob rau lub sijhawm ntev.
