Ruo n'ókè ụfọdụ, AEM bụ ngwakọta nke PEM na electrolysis ọdịnala nke diaphragm. E gosiri ụkpụrụ nke mkpụrụ ndụ electrolytic AEM na Foto nke 3. Na kathode, a na-ebelata mmiri iji mepụta hydrogen na OH -. OH - na-agafe na diaphragm gaa na anode, ebe ọ na-ejikọta ọzọ iji mepụta oxygen.
Li na ndị otu ya [1-2] mụrụ polystyrene na polyphenylene AEM nwere nnukwu arụmọrụ mmiri, nsonaazụ ya gosiri na njupụta ugbu a bụ 2.7A/cm2 na 85°C na voltaji nke 1.8V. Mgbe ha na-eji NiFe na PtRu/C dị ka ihe na-akpali akpali maka mmepụta hydrogen, njupụta ugbu a belatara nke ukwuu ruo 906mA/cm2. Chen na ndị otu ya [5] mụrụ ojiji nke ihe na-akpali akpali metal na-abụghị nke ọma na electrolyzer alkaline polymer film. E belatara NiMo oxides site na H2/NH3, NH3, H2 na N2 na okpomọkụ dị iche iche iji mepụta ihe na-akpali akpali mmepụta hydrogen electrolytic. Nsonaazụ ya gosiri na ihe na-akpali akpali NiMo-NH3/H2 nwere mbelata H2/NH3 nwere arụmọrụ kachasị mma, yana njupụta ugbu a ruo 1.0A/cm2 na arụmọrụ mgbanwe ike nke 75% na 1.57V na 80°C. Evonik Industries, nke dabere na teknụzụ akpụkpọ ahụ gas nkewa ya dị ugbu a, emepụtala ihe polymer patented maka iji na mkpụrụ ndụ electrolytic AEM ma na-agbasa mmepụta akpụkpọ ahụ ugbu a na akara nnwale. Nzọụkwụ ọzọ bụ ịchọpụta ntụkwasị obi nke sistemụ ahụ ma melite nkọwapụta batrị, ebe ọ na-eme ka mmepụta dịkwuo elu.
Ugbu a, ihe ịma aka ndị bụ isi na-eche mkpụrụ ndụ electrolytic AEM ihu bụ enweghị ike ịchịkwa ihe na iguzogide alkaline nke AEM, electrocatalyst metal dị oké ọnụ ahịa na-eme ka ọnụ ahịa nke imepụta ngwaọrụ electrolytic dịkwuo elu. N'otu oge ahụ, CO2 na-abanye na fim sel ga-ebelata iguzogide ihe nkiri na iguzogide electrolytic, si otú a na-ebelata arụmọrụ electrolytic. Nduzi mmepe nke AEM electrolyzer n'ọdịnihu bụ ndị a: 1. Mepụta AEM nwere nnukwu ike, nhọrọ ion na nkwụsi ike alkaline ogologo oge. 2. Merie nsogbu nke ọnụ ahịa dị elu nke ihe na-akpali metal dị oké ọnụ ahịa, mepụta ihe na-akpali na-enweghị metal dị oké ọnụ ahịa na arụmọrụ dị elu. 3. Ugbu a, ọnụ ahịa ebumnuche nke AEM electrolyzer bụ $20 /m2, nke kwesịrị ibelata site na ihe ndị dị ọnụ ala na usoro njikọta belatara, iji belata ọnụ ahịa zuru oke nke AEM electrolyzer. 4. Belata ọdịnaya CO2 na sel electrolytic ma melite arụmọrụ electrolytic.
