I-AEM kumlinganiselo othile luhlobo lwe-PEM kunye ne-diaphragm esekelwe kwi-lye electrolysis. Umgaqo we-AEM electrolytic cell uboniswe kuMfanekiso 3. Kwi-cathode, amanzi ayancipha ukuvelisa i-hydrogen kunye ne-OH -. OH - ihamba nge-diaphragm ukuya kwi-anode, apho iphinda idibanise ukuvelisa i-oksijini.
Li et al. [I-1-2] ifunde i-polystyrene ene-quaternized kunye ne-polyphenylene AEM ephezulu yokusebenza kwe-electrolyzer yamanzi, kwaye iziphumo zibonise ukuba ubuninzi bangoku be-2.7A / cm2 kwi-85 ° C kwi-voltage ye-1.8V. Xa usebenzisa i-NiFe kunye ne-PtRu / C njenge-catalysts yokuvelisa i-hydrogen, ukuxinana kwangoku kwehle kakhulu kwi-906mA / cm2. UChen et al. [5] wafunda ukusetyenziswa kwe-high-effective non-noble metal electrolytic catalyst kwi-alkaline polymer film electrolyzer. I-NiMo oxides yancitshiswa nge-H2 / NH3, i-NH3, i-H2 kunye neegesi ze-N2 kumaqondo okushisa ahlukeneyo ukuze kuhlanganiswe i-electrolytic hydrogen catalysts. Iziphumo zibonisa ukuba i-NiMo-NH3 / H2 i-catalyst kunye nokunciphisa i-H2 / NH3 inokusebenza kakuhle, kunye noxinano lwangoku ukuya kwi-1.0A / cm2 kunye nokuguqulwa kwamandla okusebenza kakuhle kwe-75% kwi-1.57V kunye ne-80 ° C. I-Evonik Industries, ngokusekwe kwitekhnoloji ye-membrane yokwahlula igesi ekhoyo, iye yavelisa i-polymer enelungelo elilodwa lomenzi wechiza ukuze isetyenziswe kwiiseli ze-AEM electrolytic kwaye ngoku yandisa imveliso ye-membrane kumgca wokulinga. Isinyathelo esilandelayo kukuqinisekisa ukuthembeka kwenkqubo kunye nokuphucula ukucaciswa kwebhetri, ngelixa unyusa imveliso.
Okwangoku, imingeni ephambili ejongene neeseli ze-AEM ze-electrolytic kukungabikho kwe-conductivity ephezulu kunye nokumelana ne-alkaline ye-AEM, kwaye i-electrocatalyst yentsimbi exabisekileyo inyusa iindleko zokuvelisa izixhobo ze-electrolytic. Ngelo xesha, i-CO2 ingena kwifilimu yeseli iya kunciphisa ukuxhathisa ifilimu kunye nokuxhatshazwa kwe-electrode, ngaloo ndlela inciphisa ukusebenza kwe-electrolytic. Isalathiso sophuhliso lwexesha elizayo lwe-AEM electrolyzer ngolu hlobo lulandelayo: 1. Ukuphuhlisa i-AEM nge-conductivity ephezulu, ukukhetha kwe-ion kunye nokuzinza kwe-alkaline ixesha elide. 2. Ukoyisa ingxaki yeendleko eziphezulu ze-catalyst yensimbi exabisekileyo, ukuphuhlisa i-catalyst ngaphandle kwesinyithi esixabisekileyo kunye nokusebenza okuphezulu. 3. Okwangoku, ixabiso elijoliswe kwi-electrolyzer ye-AEM yi-$ 20 / m2, efuna ukuncitshiswa ngezinto eziphathekayo ezingabizi kunye nokunciphisa amanyathelo okudibanisa, ukwenzela ukunciphisa iindleko ezipheleleyo ze-AEM electrolyzer. 4. Ukunciphisa umxholo we-CO2 kwiseli ye-electrolytic kunye nokuphucula ukusebenza kwe-electrolytic.
