FAQ
koj puas muaj lus nug?
PEM electrolysis ua haujlwm li cas?
Hauv PEM dej electrolysis, dej yog electrochemically faib ua hydrogen thiab oxygen ntawm lawv cov electrodes xws li hydrogen ntawm cathode thiab oxygen ntawm anode. PEM dej electrolysis yog tshwm sim los ntawm kev siv dej mus rau lub anode qhov twg nws tau nchuav rau hauv oxygen (O2), protons (H+) thiab electrons (e−).
Qhov txawv ntawm electrolyzer thiab PEM yog dab tsi?
Qhov sib txawv tseem ceeb ntawm alkaline electrolyser thiab proton exchange membrane electrolyser (PEM) yog dab tsi ion diffuses ntawm anode thiab cathode sab ntawm lub cell. Hauv alkaline electrolyser, alkaline OH-ions diffuse. Hauv PEM electrolyser, protons, H + ions, diffuse.
Puas yog electrolysis tshem tawm cov plaub hau mus tas li?
Yog lawm. Tsis zoo li lwm txoj kev tshem tawm cov plaub hau uas muab cov tshuaj ib ntus, Electrolysis yog ruaj khov thiab tsuas yog FDA pom zoo txoj kev tshem tawm cov plaub hau mus tas li.
Yuav ua li cas yog tias koj nres electrolysis?
Peb tsis tuaj yeem paub tias muaj pes tsawg cov plaub hau thaum kawg yuav loj hlob lossis thaum twg koj lub cev yuav txhawb kev loj hlob tshiab. Yog li ntawd nws yog ib qho tseem ceeb heev uas electrolysis yuav tsum tau ua raws li kev tshawb pom ntawm kev loj hlob. Sab laug tsis kho, cov plaub hau yuav rov tsim nws tus kheej mus rau nws qhov qub kab thiab qhov tob.
