AEM pamlingo wina wake ndi wosakanizidwa wa PEM ndi diaphragm yochokera ku electrolysis ya lye. Mfundo ya AEM electrolytic cell ikuwonetsedwa mu Chithunzi 3. Pa cathode, madzi amachepetsedwa kuti apange haidrojeni ndi OH -. OH - imayenda kudzera mu diaphragm kupita ku anode, komwe imalumikizananso kuti ipange mpweya.
Li et al. [1-2] anaphunzira kwambiri quaternized polystyrene ndi polyphenylene AEM high-performance madzi electrolyzer, ndipo zotsatira anasonyeza kuti kachulukidwe panopa anali 2.7A/cm2 pa 85 ° C pa voteji 1.8V. Mukamagwiritsa ntchito NiFe ndi PtRu/C monga chothandizira kupanga haidrojeni, kachulukidwe kameneka kamatsika kwambiri mpaka 906mA/cm2. Chen et al. [5] anaphunzira kagwiritsidwe ntchito kapamwamba kwambiri kosakhala kolemekezeka kwachitsulo chothandizira electrolytic mu alkaline polima filimu electrolyzer. Ma NiMo oxides adachepetsedwa ndi mpweya wa H2 / NH3, NH3, H2 ndi N2 pa kutentha kosiyana kuti apange zopangira ma electrolytic hydrogen. Zotsatira zikuwonetsa kuti chothandizira cha NiMo-NH3 / H2 chokhala ndi H2 / NH3 kuchepetsa chimakhala ndi ntchito yabwino kwambiri, yokhala ndi mphamvu zamakono mpaka 1.0A / cm2 ndi mphamvu yosinthira mphamvu ya 75% pa 1.57V ndi 80 ° C. Evonik Industries, kutengera ukadaulo wake wolekanitsa gasi womwe ulipo, yapanga zinthu zokhala ndi zovomerezeka za polima kuti zigwiritsidwe ntchito m'maselo a AEM electrolytic ndipo pakali pano ikukulitsa kupanga nembanemba pamzere woyendetsa. Chotsatira ndikutsimikizira kudalirika kwadongosolo ndikuwongolera mawonekedwe a batri, ndikukulitsa kupanga.
Pakadali pano, zovuta zazikulu zomwe ma cell a AEM amakumana nawo ndi kusowa kwamphamvu kwambiri komanso kukana kwa alkaline kwa AEM, ndipo electrocatalyst yamtengo wapatali yachitsulo imawonjezera mtengo wopanga zida zamagetsi. Panthawi imodzimodziyo, CO2 yolowera mufilimu ya selo idzachepetsa kukana kwa filimu ndi kukana kwa electrode, motero kuchepetsa ntchito ya electrolytic. Njira yamtsogolo yachitukuko cha AEM electrolyzer ndi motere: 1. Pangani AEM ndi ma conductivity apamwamba, kusankha kwa ion ndi kukhazikika kwa alkaline kwa nthawi yaitali. 2. Kugonjetsa vuto la mtengo wokwera wamtengo wapatali wachitsulo chothandizira, pangani chothandizira popanda zitsulo zamtengo wapatali komanso ntchito zapamwamba. 3. Pakalipano, mtengo wamtengo wapatali wa AEM electrolyzer ndi $ 20 / m2, yomwe imayenera kuchepetsedwa pogwiritsa ntchito zipangizo zotsika mtengo komanso kuchepetsa masitepe a kaphatikizidwe, kuti achepetse mtengo wonse wa AEM electrolyzer. 4. Chepetsani CO2 zomwe zili mu cell electrolytic ndikuwongolera magwiridwe antchito a electrolytic.
