AEM ndi njira yosakanikirana ya PEM ndi diaphragm yachikhalidwe yochokera ku lye electrolysis. Mfundo ya selo ya electrolytic ya AEM ikuwonetsedwa pa Chithunzi 3. Pa cathode, madzi amachepetsedwa kuti apange haidrojeni ndi OH -. OH - imayenda kudzera mu diaphragm kupita ku anode, komwe imaphatikizananso kuti ipange mpweya.
Li et al. [1-2] adaphunzira za polystyrene ndi polyphenylene AEM high-performance water electrolyzer, ndipo zotsatira zake zidawonetsa kuti kuchuluka kwa magetsi kunali 2.7A/cm2 pa 85°C pa voltage ya 1.8V. Pogwiritsa ntchito NiFe ndi PtRu/C ngati ma catalyst opangira hydrogen, kuchuluka kwa magetsi kunachepa kwambiri kufika pa 906mA/cm2. Chen et al. [5] adaphunzira kugwiritsa ntchito ma catalyst achitsulo osachita bwino kwambiri mu alkaline polymer film electrolyzer. Ma NiMo oxides adachepetsedwa ndi mpweya wa H2/NH3, NH3, H2 ndi N2 pa kutentha kosiyanasiyana kuti apange ma catalyst opanga hydrogen. Zotsatira zake zikuwonetsa kuti catalyst ya NiMo-NH3/H2 yokhala ndi H2/NH3 reduction ili ndi magwiridwe antchito abwino kwambiri, ndi kuchuluka kwa magetsi mpaka 1.0A/cm2 ndi mphamvu yosinthira mphamvu ya 75% pa 1.57V ndi 80°C. Evonik Industries, kutengera ukadaulo wake wa membrane wolekanitsa mpweya womwe ulipo, yapanga zinthu zopangidwa ndi polima zomwe zili ndi patent kuti zigwiritsidwe ntchito mu maselo a electrolytic a AEM ndipo pakadali pano ikukulitsa kupanga kwa membrane pamzere woyeserera. Gawo lotsatira ndikutsimikizira kudalirika kwa dongosololi ndikuwongolera mawonekedwe a batri, ndikuwonjezera kupanga.
Pakadali pano, mavuto akuluakulu omwe ma cell a AEM electrolytic akukumana nawo ndi kusowa kwa mphamvu yoyendetsa bwino magetsi ndi kukana kwa alkaline kwa AEM, ndipo electrocatalyst yachitsulo chamtengo wapatali imawonjezera mtengo wopanga zida zamagetsi. Nthawi yomweyo, CO2 yolowa mufilimu ya selo imachepetsa kukana kwa filimu ndi kukana kwa ma electrode, motero imachepetsa mphamvu yamagetsi. Njira yamtsogolo yopangira ma electrolyzer a AEM ndi iyi: 1. Pangani AEM yokhala ndi mphamvu yoyendetsa bwino magetsi, kusankha ma ion ndi kukhazikika kwa alkaline kwa nthawi yayitali. 2. Gonjetsani vuto la mtengo wokwera wa chothandizira chachitsulo chamtengo wapatali, pangani chothandizira popanda chitsulo chamtengo wapatali komanso magwiridwe antchito apamwamba. 3. Pakadali pano, mtengo wofunikira wa electrolyzer ya AEM ndi $20 /m2, womwe uyenera kuchepetsedwa kudzera muzinthu zotsika mtengo komanso njira zochepetsera kupanga, kuti muchepetse mtengo wonse wa electrolyzer ya AEM. 4. Chepetsani kuchuluka kwa CO2 mu cell yamagetsi ndikuwongolera magwiridwe antchito amagetsi.
