Nickel fiber ntau pom pom cov ntawv thov thoob plaws hauv ntau qhov kev lag luam. Hauv thaj chaw ntawm cov roj hlwb, cov nickel fiber ntau tau siv los ua Gas Diffusion Layer (GDL) los txhim kho kev ua haujlwm thiab ua haujlwm ntev ntawm Proton Exchange Membrane Fuel Cells (PEMFCs) thiab Khoom Roj Oxide Roj Cells (SOFCs). Nws txhawb nqa reactant faib tau zoo, txhim khu kev tswj dej, thiab txhim kho tag nrho cov xov tooj ntawm tes. Tsis tas li ntawd, nickel fiber ntau tau siv dav hauv redox flow batteries, electrolyzers, supercapacitors, thiab dej kho tshuab. Hauv cov ntawv thov no, nws ua haujlwm raws li GDL, txhim kho cov tshuaj tiv thaiv electrochemical, txhim kho roj teeb kev ua haujlwm, thiab muab tshuaj lom neeg ruaj khov thiab thaj chaw siab.

Uniform Hlau Dia

Los ntawm kev siv cov txheej txheem kev kos duab, npib tsib xee fiber ntau ua tiav cov kab hlau tsis sib xws. Qhov no uniformity ua kom zoo sib xws thiab ruaj khov, pab txhawb kev txhim kho cov khoom siv.

Lub teeb thiab Flexibility

Vim nws cov qauv ntom ntom ntom thiab fibrous, npib tsib xee fiber ntau lub teeb ci ntsa iab thiab hloov tau. Cov yam ntxwv no ua kom yooj yim tuav, shaping, thiab teeb tsa, txhim kho nws cov kev siv ntau yam hauv ntau daim ntawv thov.

Zoo Kub Kub Resistance

Nickel fiber ntau pom muaj qhov ua tau zoo ntawm qhov kub thiab txias, muaj peev xwm tiv taus kev ua haujlwm siab. Nws tuav stability txawmntawm qhov kub txog li 600 degrees Celsius, ua rau nws haum rau cov txheej txheem kub thiab xav tau daim ntawv thov.

Cov khoom siv

Roj Cells: Nickel fiber ntau yog siv los ua GDL hauv proton exchange membrane roj hlwb (PEMFCs) thiab khoom oxide roj hlwb (SOFCs). Nws pab txhawb kev faib cov reactant, txhim khu kev tswj dej, thiab txhim kho kev ua haujlwm ntawm tes.

Redox Flow Batteries: Nickel fiber ntau yog ua haujlwm raws li GDL hauv redox flow batteries, ua kom cov electrolyte ntws zoo thiab tswj xyuas cov electrode zoo ib yam.

Electrolyzers: Nws yog siv los ua GDL hauv electrolyzers los txhim kho cov tshuaj electrochemical thaum lub sij hawm tsim cov hydrogen.
