Abstract In this work, a new polymeric binder (polymer of intrinsic microporosity, PIM‐1) has been investigated and discussed to prepare and characterize composite materials for the cathodic oxygen reduction reaction. The new binder is a polymer of intrinsic microporosity, a family of organic compounds with molecularly rigid (glassy) structure, good mechanical and chemical stability. Their influence on the electrocatalytic behaviour of a commercial electrocatalyst during the oxygen reduction reaction in acidic and alkaline media has been investigated, discussed and compared to the behaviour of common cationic and anionic polymer binders, using rotating disk electrode (RDE) techniques. Polymers of intrinsic microporosity perform similarly well, and sometimes better (due to rigidity and gas permeation) when compared to commercial binders. Thus, herein, we showed that PIMs do represent a very promising and versatile alternative as binders in electrocatalysis. |
