英文摘要	One of the primary problems of the oxygen reduction reaction (ORR) for especially low and medium temperature fuel cells such as AFC, PEFC and PAFC is the high activation overpotential. This high overpotential is due to the complicated nature of the ORR and the morphological properties of the catalyst particles. High catalyst dispersion on the carbon support and small particle sizes, non-agglomeration and/or non-dissolution of the electrocatalyst is desired for the long-term operation of the electrodes. In this study electrodes were tested at different temperatures and concentrations in order to substantiate their influences on the activity and stability of the electrocatalysts, i.e.; cobalt tetraphenylporphyrin (CoTPP) and alloys of platinum and cobalt.
