PEM (Proton Exchange Membrane) electrolyzer muaj ntau yam, suav nrog:
Electrolyte membrane: Qhov no yog nyias nyias, proton-conducting membrane uas cais cov anode thiab cathode compartments hauv electrolyzer. Nws tsuas yog tso cai rau kev them nyiaj zoo hydrogen ions (protons) kom dhau mus thaum thaiv cov hluav taws xob tsis zoo.
Anode: Qhov no yog cov electrode uas cov dej tau oxidized los tsim cov pa roj carbon monoxide thiab zoo them hydrogen ions (protons). Lub anode feem ntau yog ua los ntawm cov hlau uas tiv taus corrosion, xws li titanium lossis platinum.
Cathode: Qhov no yog cov electrode uas qhov zoo them hydrogen ions (protons) thiab cov electrons tsis zoo ua ke los tsim cov roj hydrogen. Lub cathode kuj feem ntau yog ua los ntawm cov hlau uas tiv taus corrosion, xws li platinum.
Bipolar daim hlau: Cov no yog nyias, tiaj daim hlau uas ua cov electrodes hauv electrolyzer thiab tseem pab faib cov hydrogen thiab oxygen gases sib npaug. Cov phaj bipolar feem ntau yog ua los ntawm cov khoom siv hluav taws xob, xws li graphite lossis stainless hlau.
Gas diffusion khaubncaws sab nraud povtseg (GDLs): Cov no yog cov khoom ntxeem tau, cov khoom siv hluav taws xob uas tau muab tso rau ntawm cov phaj bipolar thiab cov anode thiab cathode electrodes los pab faib cov roj reactant sib npaug thiab tshem tawm cov khoom gases los ntawm qhov chaw tshuaj tiv thaiv.
Xaus daim hlau thiab cov ntsaws ruaj ruaj: Cov khoom siv no yog siv los muab lub foob hermetic rau lub electrolyzer, tiv thaiv kom tsis txhob tawm ntawm cov reactant thiab cov khoom gases.
Zuag qhia tag nrho, kev sib xyaw ntawm cov khoom no tso cai rau PEM electrolyzer faib dej rau hauv hydrogen thiab oxygen gases nrog kev ua haujlwm siab thiab kev ntseeg siab.
