AEM ku rugero runaka ni uruvange rwa PEM na electrolysis gakondo ishingiye kuri diaphragm. Ihame rya selile ya electrolytic ya AEM rigaragara ku Ishusho ya 3. Kuri cathode, amazi aragabanuka kugira ngo akore hydrogen na OH -. OH - binyura muri diaphragm bijya kuri anode, aho bihurira kugira ngo bikore ogisijeni.
Li et al. [1-2] bigaga kuri electrolyzer y’amazi ya polystyrene na polyphenylene AEM ifite quaternized cyane, kandi ibyavuye mu bushakashatsi byagaragaje ko ubucucike bw’amashanyarazi bwari 2.7A/cm2 kuri 85°C kuri voltage ya 1.8V. Mu gukoresha NiFe na PtRu/C nk'ibikatalisti mu gukora hydrogen, ubucucike bw’amashanyarazi bwagabanutse cyane bugera kuri 906mA/cm2. Chen et al. [5] bigaga ikoreshwa rya electrolyte ya electrolytic idafite amashanyarazi menshi muri electrolyze ya alkaline polymer. Oxyde za NiMo zagabanutseho H2/NH3, NH3, H2 na N2 ku bushyuhe butandukanye kugira ngo hakorwe catalyst ikora hydrogen. Ibisubizo bigaragaza ko catalyst ya NiMo-NH3/H2 ifite H2/NH3 igabanuka ifite imikorere myiza, aho ubucucike bw’amashanyarazi bugera kuri 1.0A/cm2 n’ubushobozi bwo guhindura ingufu bugera kuri 75% kuri 1.57V na 80°C. Evonik Industries, ishingiye ku ikoranabuhanga ryayo risanzwe ryo gutandukanya imyuka, yakoze ibikoresho bya polymer bifite patente byo gukoreshwa mu turemangingo twa AEM electrolytic kandi ubu irimo kwagura umusaruro wa membrane ku murongo w’igerageza. Intambwe ikurikiraho ni ukugenzura niba sisitemu ari ingirakamaro no kunoza imiterere ya bateri, mu gihe cyo kongera umusaruro.
Muri iki gihe, imbogamizi zikomeye zigaragara ku turemangingo twa AEM ni ukubura ubushobozi bwo gutwara ibintu mu buryo buhanitse no kurwanya alkaline bya AEM, kandi electrocatalyst y'icyuma cy'agaciro yongera ikiguzi cyo gukora ibikoresho bya electrolytic. Muri icyo gihe, CO2 yinjira mu firime y'ingirabuzimafatizo izagabanya ubushobozi bwo guhangana na firime no kurwanya electrolytic, bityo bikagabanya ubushobozi bwo gukoresha electrolytic. Icyerekezo cy'iterambere rya AEM electrolyzer ni iki gikurikira: 1. Guteza imbere AEM ifite ubushobozi bwo gutwara ibintu mu buryo buhanitse, guhitamo iyoni no kudahinduka kwa alkaline mu gihe kirekire. 2. Gukemura ikibazo cy'igiciro kinini cya catalyst y'icyuma cy'agaciro, guteza imbere catalyst idafite icyuma cy'agaciro n'imikorere myiza. 3. Kuri ubu, ikiguzi cyifuzwa cya AEM electrolyzer ni $20 /m2, kigomba kugabanuka binyuze mu bikoresho fatizo bihendutse no kugabanya intambwe zo gukora, kugira ngo bigabanye ikiguzi rusange cya AEM electrolyzer. 4. Kugabanya ingano ya CO2 mu turemangingo twa electrolytic no kunoza imikorere ya electrolytic.
