AEM ni murwego runaka ivanga rya PEM hamwe na diaphragm gakondo ishingiye kuri lye electrolysis. Ihame rya selile AEM electrolytique ryerekanwe mubishusho 3. Kuri cathode, amazi aragabanuka kugirango atange hydrogene na OH -. OH - inyura muri diaphragm kuri anode, aho isubirana kugirango ikore ogisijeni.
Li n'abandi. 1-2 Iyo ukoresheje NiFe na PtRu / C nk'umusemburo wo kubyara hydrogène, ubucucike buriho bwaragabanutse cyane kugera kuri 906mA / cm2. Chen n'abandi. 5 Okiside ya NiMo yagabanutseho imyuka ya H2 / NH3, NH3, H2 na N2 ku bushyuhe butandukanye kugirango ikomatanye ingufu za hydrogène hydrogène. Ibisubizo byerekana ko catisale ya NiMo-NH3 / H2 hamwe no kugabanuka kwa H2 / NH3 ifite imikorere myiza, hamwe n'ubucucike buriho kugeza kuri 1.0A / cm2 hamwe no guhindura ingufu za 75% kuri 1.57V na 80 ° C. Evonik Industries, ishingiye ku buhanga buriho bwo gutandukanya gazi ya tekinoroji ya membrane, yateje imbere ibikoresho bya polymer byemewe gukoreshwa mu ngirabuzimafatizo za AEM electrolytique kandi kuri ubu irimo kwagura umusaruro wa membrane ku murongo w'icyitegererezo. Intambwe ikurikiraho ni ukugenzura niba sisitemu yizewe no kunoza ibisobanuro bya batiri, mugihe hagabanijwe umusaruro.
Kugeza ubu, imbogamizi nyamukuru zihura na selile AEM electrolytique ni ukutagira imiyoboro ihanitse hamwe na alkaline irwanya AEM, kandi icyuma cyiza cya electrocatalysis cyongera igiciro cyo gukora ibikoresho bya electrolytike. Muri icyo gihe, CO2 yinjira muri firime ya selile bizagabanya kurwanya firime no kurwanya electrode, bityo bigabanye imikorere ya electrolytike. Icyerekezo cyiterambere kizaza cya AEM electrolyzer nuburyo bukurikira: 1. Gutezimbere AEM hamwe nubushobozi buhanitse, guhitamo ion hamwe nigihe kirekire cya alkaline. . 3. Kugeza ubu, ikiguzi cya AEM electrolyzer ni $ 20 / m2, gikeneye kugabanywa hifashishijwe ibikoresho bihendutse no kugabanya intambwe ya synthesis, kugirango bigabanye igiciro rusange cya AEM electrolyzer. 4. Kugabanya ibirimo CO2 muri selile ya electrolytike no kunoza imikorere ya electrolytike.
