Abstract: 

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.

Key words: 
fuel cell
solid polymer electrolyte
catalytic layer
