Abstract:
Platinum, which is used as cathode electrocatalysts for polymer electrolyte fuel cell, have many problems such as its high cost, small amount of resource, insufficient activity for oxygen reduction reaction (ORR) and stability. In this study, we focused on titanium, which had large amount of resources, and tried to prepare higher active catalysts by pyrolysis or combination of pyrolysis and partial oxidation of oxytitanium phthalocyanine which had both C and N. It was revealed that the partial oxidation of catalyst during heat treatment was efficient to obtain high activity of ORR. The maximum current density at 0.8V vs. RHE was about 108 mA g-cat./C-1. This result indicated that the titanium oxide-based compounds had great potential as alternative cathodes for platinum.
