Misapprehensions and Controversial Issues

The relative eontributions to eleetroeatalytie eonversion due to Ptjionomer and Ptjwater interfaees depends on phase segregation, porous morphology, and wetting properties of pores. A larger fraetion of hydrophilie mieropores will inerease the eontribution of Ptjwater interfaees relative to that of Ptjionomer interfaees [50, 51]. 

The nature of eleetroeatalytieally aetive eatalyst surfaees is related to the vital but largely unsettled issue of agglomeration of earbon/Pt and spontaneous phase segregation between primary partieles of earbon/Pt and ionomer moleeules. This
