Kufambira mberi uye kuongororwa kwehupfumi kweion exchange membrane (AEM) hydroelectrolysis yekugadzirwa kwehydrogen

AEM kune imwe nhanho isanganiswa yePEM uye yechinyakare diaphragm yakavakirwa lye electrolysis. Nheyo yeAEM electrolytic cell inoratidzwa muMufananidzo 3. Pakathodhi, mvura inoderedzwa kubudisa hydrogen uye OH -. OH - inoyerera kuburikidza nediaphragm kune anode, iyo inobatana zvakare kuti ibudise oksijeni.

Li et al. [1-2] akadzidza zvikuru quaternized polystyrene uye polyphenylene AEM yakakwirira-performance mvura electrolyzer, uye zvigumisiro zvakaratidza kuti density ikozvino yaiva 2.7A / cm2 pa 85 ° C pamhepo ye1.8V. Paunenge uchishandisa NiFe nePtRu/C sezvinokonzera kugadzirwa kwehydrogen, huwandu hwazvino hwakadzikira zvakanyanya kusvika ku906mA/cm2. Chen et al. [5] akadzidza kushandiswa kwepamusoro-soro isina-noble metal electrolytic catalyst mu alkaline polymer film electrolyzer. NiMo oxides yakaderedzwa neH2/NH3, NH3, H2 uye N2 magasi patembiricha dzakasiyana kubatanidza electrolytic hydrogen kugadzira catalysts. Mhedzisiro yacho inoratidza kuti NiMo-NH3/H2 catalyst ine H2/NH3 kuderedza ine yakanakisa kuita, ine density iripo kusvika ku1.0A/cm2 uye simba rekushandura simba re75% pa1.57V uye 80 ° C. Evonik Industries, zvichibva pane iripo gasi yekuparadzanisa membrane tekinoroji, yakagadzira patented polymer zvinhu zvekushandisa muAEM electrolytic maseru uye parizvino iri kuwedzera kugadzirwa kwe membrane pamutsetse wendege. Nhanho inotevera ndeyekuona kuvimbika kweiyo sisitimu uye kugadzirisa bhatiri kutsanangurwa, uku uchiwedzera kugadzirwa.

Parizvino, matambudziko makuru akatarisana neAEM electrolytic masero kushaikwa kwepamusoro conductivity uye alkaline kuramba kweAEM, uye yakakosha simbi electrocatalyst inowedzera mutengo wekugadzira michina yemagetsi. Panguva imwecheteyo, CO2 inopinda musero firimu inoderedza kupikisa kwefirimu uye kupikisa kwe electrode, nokudaro kuderedza kushanda kwe electrolytic. Iro remangwana rekuvandudza kutungamira kweAEM electrolyzer ndeiyi inotevera: 1. Gadzira AEM ine high conductivity, ion selectivity uye kwenguva refu alkaline kugadzikana. 2. Kunda dambudziko rekudhura kwemari yakakosha yesimbi catalyst, gadzira catalyst pasina simbi inokosha uye kushanda kwepamusoro. 3. Parizvino, chinangwa chemutengo weAEM electrolyzer i $ 20 / m2, iyo inoda kuderedzwa kuburikidza nezvinhu zvakachipa zvakasvibirira uye kuderedza matanho ekugadzirisa, kuitira kuderedza mari yose yeAEM electrolyzer. 4. Deredza CO2 zvinyorwa mu electrolytic cell uye kuvandudza electrolytic performance.
