Nickel nthuav mesh (feem ntau hu ua npib tsib xee hlau mesh lossis stretched nickel mesh) nthuav tawm ntau yam khoom uas ua rau nws tsim nyog rau kev siv roj ntawm tes. Roj hlwb, xws li proton exchange membrane (PEM) los yog khoom oxide roj hlwb (SOFC), yuav tsum tau cov ntaub ntawv uas muaj corrosion kuj, thermal stability, thiab hluav taws xob conductivity los lis electrochemical tshuaj cuam tshuam nrog hydrogen los yog lwm yam roj.
Dab tsi yog qhov zoo ntawm nickel nthuav mesh hauv roj hlwb?
Hluav taws xob conductivity zoo heev
Nickel muab cov hluav taws xob hloov pauv tau zoo, ua kom nthuav dav mesh ib qho kev txhim khu kev qha tam sim no hauv ntau hom roj ntawm tes.
Siab Corrosion Resistance
Cov roj ntsha feem ntau ua haujlwm nyob rau hauv ib puag ncig chemical hnyav (acidic, alkaline, lossis siab -kub). Nickel nthuav mesh tiv thaiv corrosion, ncua kev pab cuam lub neej.
Mechanical Strength & Stability
Cov qauv mesh nthuav dav muaj kev nruj nrog kev yoog raws, muab sijhawm ntev - kev ruaj ntseg nyob rau hauv txhua yam kev ntxhov siab thiab thermal cycling.
High Gas Diffusion
Qhov qhib mesh tsim tso cai rau kev faib cov pa roj (hydrogen thiab oxygen), uas yog qhov tseem ceeb rau kev txhim kho cov tshuaj tiv thaiv electrochemical.
Hom Roj Cell Applications ntawm Nickel Expanded Mesh
PEMFC (Proton Exchange Membrane Roj Cell): Siv los ua cov khoom siv tam sim no thiab cov khoom siv hluav taws xob.
AFC (Alkaline Fuel Cell): Ua haujlwm li roj diffusion electrode substrate.
SOFC (Solid Oxide Fuel Cell): Ua ke nrog cov ceramics (piv txwv li, Ni-YSZ) raws li kev txhawb nqa anode.
DMFC (Direct Methanol Roj Cell): Muaj nuj nqi raws li catalyst cab kuj thiab ntws distributor.
