твердополимерный электролит

Depolarization of anode by sulfurous anhydride allows to reduce power inputs on hydrogen production in 1.5 times. The reason which prevents commercialization of this process is realization impossibility of industrial electrolysis current density because of SO₂ feeding diffusion limitation to anodic catalytic layer. Pressure influence on water electrolysis process with depolarization anode by sulfurous anhydride in solid polymer electrolyte electrolyzers is examined.

Composition and structure of proton-exchange membrane fuel cell catalytic layers were investigated. Modelling of catalytic layer vas considered. This model allows to calculate layers containing particles of polymer and the catalyst of various forms and sizes. Dependence of conductivity and active layer surface area on concentration of polymer particles is shown. Best performance of a fuel cell is observed at the polymer concentration in a layer of 30–35% vol.
