This paper studies the electrochemical properties of ppy/Pt‐Cu composite for oxygen reduction reaction (ORR) and compares it to the highly porous ppy/Pt‐Cu catalyst, which can be synthesized by galvanostatic method (ppy/Pt‐Cu(GS)). The results of the polarization, rotating disk electrode and electrochemical impedance tests are discussed to determine the electrochemical properties of the catalysts. According to the results, ppy/Pt‐Cu(GS) catalyst is more active toward ORR compared to ppy/Pt‐Cu catalyst. The rotating disk electrode data indicates four‐electron transfer mechanism for this catalyst.
