I-AEM ngokwezinga elithile iyingxube ye-PEM kanye ne-diaphragm esekelwe ku-lye electrolysis. Isimiso se-AEM electrolytic cell siboniswa kuMfanekiso 3. Ku-cathode, amanzi ancishiswa ukuze akhiqize i-hydrogen ne-OH -. OH - igeleza nge-diaphragm iye ku-anode, lapho iphinde ihlangane khona ukuze ikhiqize umoya-mpilo.
Li et al. [I-1-2] ifunde i-polystyrene ene-quaternized ne-polyphenylene AEM ephezulu yokusebenza kwamanzi e-electrolyzer, futhi imiphumela yabonisa ukuthi ukuminyana kwamanje kwakuyi-2.7A / cm2 ku-85 ° C ku-voltage ye-1.8V. Uma usebenzisa i-NiFe ne-PtRu/C njengezisusa zokukhiqizwa kwe-hydrogen, ukuminyana kwamanje kwehle kakhulu kuya ku-906mA/cm2. U-Chen et al. [5] ufunde ukusetshenziswa kwe-electrolytic catalyst esebenza kahle kakhulu yensimbi ku-alkaline polymer film electrolyzer. Ama-NiMo oxides ancishiswa ngamagesi e-H2/NH3, NH3, H2 kanye ne-N2 emazingeni okushisa ahlukene ukuze kuhlanganiswe ama-catalyst okukhiqiza i-hydrogen electrolytic. Imiphumela ibonisa ukuthi i-catalyst ye-NiMo-NH3/H2 ngokuncishiswa kwe-H2/NH3 inokusebenza okungcono kakhulu, ngokuminyana kwamanje kufika ku-1.0A/cm2 kanye nokusebenza kahle kokuguqulwa kwamandla okungu-75% ku-1.57V naku-80°C. I-Evonik Industries, ngokusekelwe kubuchwepheshe bayo obukhona bokwahlukanisa igesi, isungule impahla ye-polymer enelungelo lobunikazi ukuze isetshenziswe kumaseli e-AEM electrolytic futhi njengamanje yandisa ukukhiqizwa kolwelwesi kulayini wokuhlola. Isinyathelo esilandelayo siwukuqinisekisa ukwethembeka kwesistimu nokuthuthukisa ukucaciswa kwebhethri, kuyilapho ukhuphula ukukhiqizwa.
Njengamanje, izinselelo ezinkulu ezibhekene namaseli e-AEM e-electrolytic ukuntuleka kokusebenza okuphezulu nokumelana ne-alkaline kwe-AEM, futhi i-electrocatalyst yensimbi eyigugu inyusa izindleko zokukhiqiza amadivaysi e-electrolytic. Ngesikhathi esifanayo, i-CO2 ingena kwifilimu yeseli izonciphisa ukumelana kwefilimu nokumelana ne-electrode, ngaleyo ndlela kunciphise ukusebenza kwe-electrolytic. Isiqondiso sokuthuthukiswa kwesikhathi esizayo se-AEM electrolyzer simi kanje: 1. Thuthukisa i-AEM nge-conductivity ephezulu, ukukhetha kwe-ion kanye nokuzinza kwe-alkaline yesikhathi eside. 2. Nqoba inkinga yezindleko eziphezulu ze-catalyst yensimbi eyigugu, ukuthuthukisa i-catalyst ngaphandle kwensimbi eyigugu nokusebenza okuphezulu. 3. Okwamanje, izindleko ezihlosiwe ze-AEM electrolyzer zingu-$20/m2, okudingeka zincishiswe ngezinto ezingavuthiwe ezishibhile kanye nezinyathelo zokuhlanganiswa ezincishisiwe, ukuze kwehliswe izindleko zizonke ze-AEM electrolyzer. 4. Yehlisa okuqukethwe kwe-CO2 kuseli ye-electrolytic futhi uthuthukise ukusebenza kwe-electrolytic.
