Quid differentias inter an AEM et PEM Electrolyzer?
2025-02-24
Ⅰ. Productum structura differentias
|
Collatio dimensiones |
AEM Electrolyzer |
Pem electrolyzer |
|
Membrana materiae |
Anion commutationem membrana (faciendi oh⁻ ions), plerumque polymers in alkaline environments (ut Quaterned Polyyletheretroone). |
Proton Exchange membrana (deducendi H⁺ ions), communiter perfluorosulfonic acidum membranam (ut nafion), requirit acidic amet pro stabilitate. |
|
Catalyst |
Non pretioso metallum catalysts (ut nickel et ferrum-fundatur materiae) potest esse, quae sunt relative humilis in sumptus. |
Non pretioso metallum catalysts (ut nickel et ferrum-fundatur materiae) potest esse, quae sunt relative humilis in sumptus. |
|
Electrode structuram |
Raro electrodes plerumque combined alkaline electrolytes (ut Koh solutiones), cum liquido electrolytes utrinque membrana. |
Firmus electrolytes, in electrodes sunt in directum contactus cum membrana, non liquida electrolyte non requiritur, et structura est pacto. |
|
Bipolar laminam materiae |
Cheap metalla (ut immaculatam ferro) vel graphite potest esse, quod repugnant ad alkaline corrosio. |
Titanium aut aurum, patella materiae non requiritur ad vitare acidic corrosio, quae est relative pretiosa. |
|
Opus temperatus |
Usually 60-80 ℃, minus temperatus operatio requiritur ad ponere membrana stabilitatem. |
Potest operari ad 70-90 ℃ et altus-pressura cogitationes potest pervenire altius temperaturis. |
|
Pressura |
Plerumque in humili-medium pressionem range ( |
Potest directe agunt ad altum pressura (> XXX vectes), reducendo subsequent hydrogenii compressionem industria consummatio. |
Ⅱ. Perficientur et pretium collatio
|
Parametri |
AEM Electrolyzer |
Pem electrolyzer |
|
Current density |
Minimum (0.5-1.5 A / C²) |
Princeps (1.5-3.0 A / C²) |
|
Efficacitas |
De 60-70% (ratio efficientiam) |
De 70-80% (ratio efficientiam) |
|
Satus-sursum responsio celeritate |
Tardus (opus ad Preheat electrolyte) |
Maxime ieiunium (responsio in seconds) |
|
Lifespan |
De 20000,000-40,000 horas (pendeat membrana stabilitas) |
De 50,000-80,000 horae (Pretiosi metallum Catalysts habere princeps diuturnitatem) |
|
Material sumptus |
Minimum (Non-Pretiosa Metalysts, cheap Bipolar lamines) |
Minimum (Non-Pretiosa Metalysts, cheap Bipolar lamines) |
|
Sustentationem complexionem |
Princeps (postulo reponere alkaline electrolyte semper) |
Minimum (solidum electrolytes sunt sustentacionem, liberum) |
Ⅲ. Differentias in application missionibus
● AEM Electrolyzer:
Applicer scenarios: Medium et humilis volatility missionibus (ut firmum ventum potentia / hydropower), requiring humilis-sumptus, diu terminus operationem magnarum-scale hydrogenii productio projects.
Casus: Green Hydrogenii copia ad magnum off-malesuada hydrogenii productio stationibus et industriae parcis.
● PEM Electrolyzer:
Applicer scenarios: Maxime Volatile Renewable Energy (ut photovoltaics, instabiles ventus potentia), requiring ieiunium satus et subsisto et dynamic responsio.
Casus: Distributed Energy Systems, Hydrogenii productio facilities combined cum eget frequency ordinacione.
● AEM Electrolyzer:
Applicer scenarios: Fixum hydrogenii refueling statio (cost-sensitivo), cum humilis requisita responsione celeritatem.
● PEM Electrolyzer:
Applicer scenarios: Mobile aut pacto hydrogenii refueling statio (ut portubus, via servitium areas), requiring ieiunium impletionem et altus potestate densitate.
III. Industrial Applications
● AEM Electrolyzer:
Applicer scenarios: Green Hydrogenium replacement pro traditional eget plantis (ut Sacchas Ammonia, conflans), requiring magna-scale, humilis-cost hydrogenii.
● PEM Electrolyzer:
Applicer scenarios: High-puritatem hydrogenii demanda (ut electronics industria, cella cell vehicles), summus pressura recta hydrogenii copia requiritur.
● AEM Electrolyzer:
Commoda: Resistant ad alkaline environment, idoneam ad searchater desalination copulata hydrogenii productio (pretreatment requiritur).
● PEM Electrolyzer:
Commoda: Acidum resistentia, princeps pressura, idoneam ad pacto hydrogenii productio in altum mare et extrema environment.
IV. Technology Development Tract
●AEM Electrolyzer:
Investigationis directionem: Development of summus stabilitate anion commutationem membrana, non-clarior metallum catalyst optimization.
Meta: Ad augmentum current density ad 1.5-2.0 a / CM², et extend vitam plus quam 50.000 horas.
● Pem electrolyzer:
Investigationis directionem: Redigendum moles gemmas metallorum (ut iridium pro platinum) et amplio mechanica robur membranam.
Meta: Redigo costs per XXX% -50%, aptet ad C% renewable industria fluctuatione missione.
