AEM kusvika padanho rakati imhando yePEM uye diaphragm based lye electrolysis. Nheyo yeAEM electrolytic cell inoratidzwa muMufananidzo 3. Pa cathode, mvura inoderedzwa kuti ibudise hydrogen uye OH -. OH - inoyerera nepa diaphragm ichienda kune anode, uko inobatanazve kuti ibudise oxygen.
Li et al. [1-2] vakadzidza polystyrene ne polyphenylene AEM high-performance water electrolyzer zvine quaternized, uye mhedzisiro yakaratidza kuti current density yaive 2.7A/cm2 pa 85°C pa voltage ye 1.8V. Pavaishandisa NiFe nePtRu/C se catalysts pakugadzirwa kwe hydrogen, current density yakaderera zvakanyanya kusvika 906mA/cm2. Chen et al. [5] vakadzidza kushandiswa kwe high-efficiency non-noble metal electrolytic catalyst mu alkaline polymer film electrolyzer. NiMo oxides dzakaderedzwa ne H2/NH3, NH3, H2 ne N2 gases patembiricha dzakasiyana kugadzira electrolytic hydrogen production catalysts. Mhedzisiro yacho inoratidza kuti NiMo-NH3/H2 catalyst ine H2/NH3 reduction ine performance yakanakisa, ine current density inosvika 1.0A/cm2 uye energy conversion efficiency ye 75% pa 1.57V ne 80°C. Evonik Industries, zvichibva pahunyanzvi hwayo hwekuparadzanisa magasi, yakagadzira polymer yakagadzirwa nepatent kuti ishandiswe mumasero emagetsi eAEM uye parizvino iri kuwedzera kugadzirwa kwema membrane pamutsetse wekuedza. Danho rinotevera nderekuona kuvimbika kwesystem uye kuvandudza zvinodiwa zvemabhatiri, ukuwo ichikwidza kugadzirwa.
Parizvino, matambudziko makuru anotarisana nemasero emagetsi eAEM kushaikwa kweAEM ine simba rekufambisa magetsi uye alkaline, uye electrocatalyst yesimbi inokosha inowedzera mutengo wekugadzira michina yemagetsi. Panguva imwe chete, CO2 inopinda mufirimu yesero inoderedza simba rekufambisa magetsi uye electrode, nokudaro ichideredza simba remagetsi. Nzira yekuvandudza yeAEM electrolyzer mune ramangwana ndeiyi inotevera: 1. Gadzira AEM ine simba rekufambisa magetsi, kusarudza maion uye kugadzikana kwenguva refu kwealkaline. 2. Kukunda dambudziko remutengo wakakwira wesimbi inokosha, gadzira catalyst isina simbi inokosha uye kushanda kwepamusoro. 3. Parizvino, mutengo weAEM electrolyzer i$20 /m2, iyo inoda kuderedzwa kuburikidza nezvinhu zvakachipa uye matanho ekuderedza synthesis, kuitira kuderedza mutengo wese weAEM electrolyzer. 4. Deredza huwandu hweCO2 mumasero emagetsi uye kuvandudza mashandiro emagetsi.
