In this study we have tested some alternative catalysts for oxygen reduction in an alkaline electrolyte . The catalysts tested were: , , Pt (for comparison), and . The electrodes were manufactured by the rolling method. The best electrodes made in this way were tested in a long run test, testing times ranging from 425 to 660 h. The decay in potential during the 660 h run was 0.041 mV/h.
