Research and investigation of catalytic layers of proton-exchange membrane fuel cell

Composition and structure of proton-exchange membrane (PEM) fuel cell catalytic layers were investigated. The maximum FC efficiency was observed at the polymer content in a layer 25-30 vol.% at work on air and 30-35 vol. % at work on oxygen. At a variation of quantity of catalytic composition the maximum current density have been received at layer load 1.75 mg/sm2, thus decrease in it value in 2 times leads to falling of current density only on 10%.
