AEM ho isa boholeng bo itseng ke lebasetere la PEM le electrolysis ea li-diaphragm ea setso. Molao-motheo oa sele ea electrolytic ea AEM e bontšoa ho Setšoantšo sa 3. Ho cathode, metsi a fokotsehile ho hlahisa hydrogen le OH -. OH - e phalla ka diaphragm ho anode, moo e kopanang hape ho hlahisa oksijene.
Li et al. [1-2] o ile a ithuta polystyrene e nang le quaternized haholo le polyphenylene AEM e sebetsang hantle haholo ea metsi a electrolyzer, 'me liphello li bontšitse hore sekhahla sa hona joale e ne e le 2.7A / cm2 ho 85 ° C ka motlakase oa 1.8V. Ha u sebelisa NiFe le PtRu / C e le li-catalysts bakeng sa tlhahiso ea hydrogen, palo ea hona joale e fokotsehile haholo ho 906mA / cm2. Chen le ba bang. [5] o ile a ithuta tšebeliso ea matla a phahameng a non-noble metal electrolytic catalyst ka alkaline polymer film electrolyzer. Li-oxide tsa NiMo li ile tsa fokotsoa ke likhase tsa H2 / NH3, NH3, H2 le N2 ka mocheso o fapaneng ho etsa li-catalyst tsa tlhahiso ea electrolytic hydrogen. Liphello li bontša hore NiMo-NH3 / H2 e fokotsang H2 / NH3 e na le ts'ebetso e ntle ka ho fetisisa, e nang le sekhahla sa hona joale ho fihlela ho 1.0A / cm2 le matla a ho fetola matla a 75% ho 1.57V le 80 ° C. Evonik Industries, e ipapisitseng le thekenoloji ea eona e teng ea membrane ea karohano ea khase, e thehile thepa ea polymer e nang le patent bakeng sa ho sebelisoa liseleng tsa AEM electrolytic mme hajoale e ntse e holisa tlhahiso ea membrane moleng oa sefofane. Mohato o latelang ke ho netefatsa ho ts'epahala ha sistimi le ho ntlafatsa lintlha tsa betri, ha o ntse o eketsa tlhahiso.
Hajoale, liphephetso tse kholo tse tobaneng le lisele tsa AEM tsa electrolytic ke khaello ea conductivity e phahameng le khanyetso ea alkaline ea AEM, mme motlakase oa tšepe oa bohlokoa o eketsa litšenyehelo tsa ho etsa lisebelisoa tsa electrolytic. Ka nako e ts'oanang, CO2 e kenang filimi ea sele e tla fokotsa ho hanyetsa filimi le ho hanyetsa electrode, kahoo e fokotsa ts'ebetso ea electrolytic. Tataiso ea ntlafatso ea nakong e tlang ea electrolyzer ea AEM e tjena: 1. Hlahisa AEM ka conductivity e phahameng, khetho ea ion le botsitso ba nako e telele ea alkaline. 2. Hlōla bothata ba litšenyehelo tse phahameng tsa tšepe ea bohlokoa ea tšepe, ho hlahisa li-catalyst ntle le tšepe ea bohlokoa le ts'ebetso e phahameng. 3. Hona joale, theko e lebisitsoeng ea AEM electrolyzer ke $ 20 / m2, e lokelang ho fokotsoa ka thepa e theko e tlaase le ho fokotsa mehato ea ho kopanya, e le ho fokotsa litšenyehelo tse akaretsang tsa AEM electrolyzer. 4. Fokotsa litaba tsa CO2 ka seleng ea electrolytic le ho ntlafatsa ts'ebetso ea electrolytic.
