AEM har zuwa wani nau'i ne na PEM da diaphragm na al'ada na tushen lye electrolysis. An nuna ka'idar AEM electrolytic cell a cikin Hoto 3. A cathode, an rage ruwa don samar da hydrogen da OH -. OH - yana gudana ta cikin diaphragm zuwa anode, inda ya sake haɗuwa don samar da oxygen.
Li et al. [1-2] yayi nazari sosai na polystyrene da polyphenylene AEM high-performance water electrolyzer, kuma sakamakon ya nuna cewa yawancin halin yanzu shine 2.7A / cm2 a 85 ° C a ƙarfin lantarki na 1.8V. Lokacin amfani da NiFe da PtRu/C a matsayin masu haɓaka samar da hydrogen, yawan adadin yanzu ya ragu sosai zuwa 906mA/cm2. Chen et al. [5] yayi nazarin aikace-aikace na babban inganci mara kyau na ƙarfe electrolytic mai kara kuzari a cikin alkaline polymer film electrolyzer. NiMo oxides an rage ta H2/NH3, NH3, H2 da N2 gas a yanayi daban-daban don hada electrolytic hydrogen samar da kuzari. Sakamakon ya nuna cewa NiMo-NH3 / H2 mai haɓakawa tare da raguwar H2 / NH3 yana da mafi kyawun aiki, tare da yawa na yanzu har zuwa 1.0A / cm2 da ƙarfin jujjuyawar makamashi na 75% a 1.57V da 80 ° C. Masana'antu na Evonik, dangane da fasahar rabuwar iskar gas ɗin da ta wanzu, ta ɓullo da ƙwaƙƙwaran kayan polymer don amfani a cikin sel na AEM na lantarki kuma a halin yanzu suna haɓaka samar da membrane akan layin matukin jirgi. Mataki na gaba shine tabbatar da amincin tsarin da haɓaka ƙayyadaddun baturi, yayin haɓaka samarwa.
A halin yanzu, babban ƙalubalen da ke fuskantar sel na AEM electrolytic shine rashin ƙarfin aiki mai ƙarfi da juriya na alkaline na AEM, kuma ƙarfe mai ƙima mai daraja yana ƙara farashin kera na'urorin lantarki. A lokaci guda, CO2 shiga cikin fim din tantanin halitta zai rage juriya na fim da juriya na lantarki, don haka rage aikin lantarki. Hanyar ci gaba na gaba na AEM electrolyzer shine kamar haka: 1. Haɓaka AEM tare da babban aiki, zaɓin ion da kwanciyar hankali na alkaline na dogon lokaci. 2. Cin nasara da matsala na tsada mai tsada mai mahimmanci na ƙarfe mai mahimmanci, haɓaka mai haɓakawa ba tare da ƙarfe mai daraja da babban aiki ba. 3. A halin yanzu, farashin da aka yi niyya na AEM electrolyzer shine $ 20 / m2, wanda ke buƙatar ragewa ta hanyar albarkatun ƙasa mai arha da rage matakan haɓakawa, don rage yawan farashin AEM electrolyzer. 4. Rage abun ciki na CO2 a cikin cell electrolytic kuma inganta aikin lantarki.
