Low-energy ball-milling causes particles fragmentation and break of aggregations. Fragmentation of the catalyst particles improves its electrochemical activity. Ball milling of ink causes chemical and physical changes to the catalyst surface. Too high Nafion amound blocks the access of the electrolyte to the catalyst surface.
