Ionomer distribution in catalyst layer
Web12 dec. 2008 · The ionomer content seems to influence the catalyst layer resistance in the anode and cathode and also the methanol oxidation potential on the anode. On the cathode, catalyst utilisation is seen to be affected by the ionomer content. Cyclic voltammetry (CV) is used to study the effect of ionomer content on Platinum (Pt) utilisation on the cathode.
