The invention refers to an oxygen reduction electrode comprising at least three layers: a current collector; a diffusion layer comprising at least PTFE; and a catalytical active layer, comprising at least a mixture of perovskites and pyrolysed macrocycles. In this way, oxygen may be utilised from air without an initial removal of carbon dioxide. Moreover, the invention refers to methods for preparing the electrode, as well as fuel cells and other products wherein the electrode can be used.
