I-AEM ngezinga elithile iyinhlanganisela ye-PEM kanye ne-electrolysis yendabuko esekelwe ku-diaphragm. Isimiso se-AEM electrolytic cell siboniswe kuMfanekiso 3. Ku-cathode, amanzi ayancishiswa ukuze akhiqize i-hydrogen kanye ne-OH -. OH - egeleza nge-diaphragm iye ku-anode, lapho ihlangana khona ukuze ikhiqize i-oxygen.
ULi et al. [1-2] bafunde i-polystyrene ehlanganisiwe kakhulu kanye ne-polyphenylene AEM high-performance water electrolyzer, futhi imiphumela ibonise ukuthi ubuningi bamanje babungu-2.7A/cm2 ku-85°C ku-voltage engu-1.8V. Lapho besebenzisa i-NiFe kanye ne-PtRu/C njenge-catalysts zokukhiqizwa kwe-hydrogen, ubuningi bamanje behle kakhulu baba ngu-906mA/cm2. UChen et al. [5] bafunde ukusetshenziswa kwe-catalyst ye-electrolytic yensimbi engasebenzi kahle kakhulu ku-electrolyzer yefilimu ye-alkaline polymer. Ama-oxide e-NiMo ancishiswe ngamagesi e-H2/NH3, NH3, H2 kanye ne-N2 emazingeni okushisa ahlukene ukuze kuhlanganiswe ama-catalysts okukhiqizwa kwe-hydrogen e-electrolytic. Imiphumela ikhombisa ukuthi i-catalyst ye-NiMo-NH3/H2 enokunciphisa kwe-H2/NH3 inokusebenza okuhle kakhulu, ngobuningi bamanje obufika ku-1.0A/cm2 kanye nokusebenza kahle kokuguqulwa kwamandla okungu-75% ku-1.57V kanye no-80°C. I-Evonik Industries, ngokusekelwe kubuchwepheshe bayo be-membrane yokuhlukanisa igesi obukhona, ithuthukise izinto ze-polymer ezinelungelo lobunikazi zokusetshenziswa kumaseli e-electrolytic e-AEM futhi okwamanje yandisa ukukhiqizwa kwe-membrane emgqeni wokuhlola. Isinyathelo esilandelayo ukuqinisekisa ukuthembeka kohlelo nokuthuthukisa imininingwane yebhethri, ngenkathi kwandiswa ukukhiqizwa.
Njengamanje, izinselele ezinkulu ezibhekene namaseli e-electrolytic e-AEM ukuntuleka komoya ophezulu kanye nokumelana kwe-alkaline kwe-AEM, kanti i-electrocatalyst yensimbi eyigugu ikhulisa izindleko zokukhiqiza amadivayisi e-electrolytic. Ngesikhathi esifanayo, i-CO2 engena efilimini yeseli izonciphisa ukumelana kwefilimu kanye nokumelana kwe-electrode, ngaleyo ndlela inciphise ukusebenza kwe-electrolytic. Isiqondiso sentuthuko yesikhathi esizayo se-electrolyzer ye-AEM simi kanje: 1. Thuthukisa i-AEM ngomoya ophezulu, ukukhetha kwe-ion kanye nokuzinza kwe-alkaline yesikhathi eside. 2. Nqoba inkinga yezindleko eziphezulu ze-catalyst yensimbi eyigugu, thuthukisa i-catalyst ngaphandle kwensimbi eyigugu kanye nokusebenza okuphezulu. 3. Njengamanje, izindleko eziqondiwe ze-electrolyzer ye-AEM zingama-$20 /m2, okudingeka zincishiswe ngezinto zokusetshenziswa ezishibhile kanye nezinyathelo zokwenziwa ezincishisiwe, ukuze kuncishiswe izindleko eziphelele ze-electrolyzer ye-AEM. 4. Nciphisa okuqukethwe kwe-CO2 kuseli ye-electrolytic futhi uthuthukise ukusebenza kwe-electrolytic.
