PEM aqua electrolysis hydrogenii productio ratio compositionem

PEM aqua electrolysis hydrogenii productio ratio estPem electrolyzeret auxilia (bop).

Pem electrolyzerEst core parte pem aqua electrolysis hydrogenii productio fabrica. Maxime basic component unitas electrolyzer est electrolytic cellula. Fretus in potestate, in pem electrolyzer habet dozens vel etiam centum electrolytic cellulis. Quisque electrolytic cellula consistit ex V partibus, ex intus ad extra, suntProton Exchange membrana, Catalyst,Gas Diffusio Layeretbipolar laminam.

Schematic diagram internum structuram de pem electrolyzer

1. Proton Exchange membrana

Proton Exchange membrana est unus ex Core components ofPem electrolyzer. In PEM electrolyzer, the proton exchange membrane acts as a channel for proton exchange, and as a barrier to prevent the hydrogen and oxygen produced by the cathode and anode from contacting each other, and provides support for the catalyst coating. Ideo et protón commutationem membrana necessitates ad maxime princeps protón conductivity et aer emissiones, et maxime humilis electroned.

Simul proton commutationem membrana etiam indiget bonam eget stabilitatem posse sustinere fortis acidic operantes amet; Fortis hydrophilicity est etiam essential, quod potest ne loci aquae inopia protón commutationem membrana et vitare siccum ardenti. In perficientur de protón commutationem membrana directe afficit operating efficientiam et vitam PEM electrolyzer.

Processing de Proton Exchange membrana adhuc difficile. Comparari cum Proton Exchange membrana in cibus cellulis (crassitudine de X microns), in protón commutationem membrana in PEM Electrolyzers est densior (150-200 et deformatio in dispensando, et tumor ad superioris, ut processus magis difficilis.

2. Catalyst

Et Cathode et Anode Catalysts sunt momenti components de pem electrolyzer. Cum catalysts et Cathode et Anode Catalysts sunt in locis electroChemical reactiones, in catalysts opus est bonum corrosio resistentia, catalytic operatio, electronic conductivity et Porosity ut PEM Electrolyzer potest operari stabiliter.

Comparari cum cibus cellulis, pem electrolyzers magis in pretioso metallum materiae in usum catalysts. In fortis acidic operating environment of pem electroly, non-pretiosum metallum materiae sunt susceptibilis ad corrosio et ut miscere cum sulfonic acidum et iones in protón commutationem membranam, reducendo in opus perficientur de protón membrana commutatione. Et communiter cathode catalyst est a platinum-ipsum catalyst cum ipsum sicut carrier materia, cum iridium cadmiae est maxime late usus Anode Catalyst.

3. Gas Diffusio Layer

Quod Gas diffusio layer, etiam quae current collector, est porellum layer sandwiched inter Anode et bipolar laminam. Et Gas diffusione accumsan serves ut pontem connectens bipolar laminam et catalyst iacuit, ensuring ad tradenda Gas et liquida inter bipolar laminam et catalyst iacuit, et efficaciora electronica conduction.

In anode liquido aquae conducted ad catalyst accumsan per Gas diffusio layer et decompositis in oxygeni, protons et electrons. Generatur oxygeni fluit ad bipolar laminam per Gas diffusio layer, protons conducted ad cathodem per protón commutationem membranam et electrons conducted ad Anode Bipolar laminam per Gas Diffusum et intrare externum.

Cathode electrons intrare catalys catalyst ex externo circuitu per Gas diffusionem accumsan et agere cum protons ad producendum hydrogenii. Generated Hydrogenium fluit ad bipolar laminam per Gas diffusione layer. Igitur ut ad Gas et liquor onerariam efficientiam et conductivity, Gas diffusionem accumsan necessitates oportet utrumque convenientem Porosity et bonum conductivity ad curare electronic transmissionem efficientiam.

4. Bipolar laminam

Et bipolar laminam non solum sustineat component ad membranam electrode et Gas diffusio layer, sed etiam magni momenti alveo pro convergens gases (hydrogenii et oxygeni) et electrons. Bipolar laminis utrimque Anode et cathode respectively convergens Hydrogenii generatae a cathode et oxygeni generatae ab Anode et output eos.

Ideo bipolar laminam necessitates habere altum mechanica stabilitatem, eget stabilitatem et humilis hydrogenii permeability. Electrons generatae Anode intrare externa circuitus per Anode bipolar laminam et intrabit in catalyst catalyst per cathode bipolar laminam. Unde et bipolar laminam etiam indiget habere altus conductivity.

Auxiliaris ratio de PEM aqua electrolysis hydrogenii productio fabrica includit quattuor major systems: Vox copia ratio, hydrogenium siccatio et purificatio ratio, deionized aqua ratio et refrigerationem ratio.
