摘要： The present invention relates to an electrochemical catalyst structure and a method for producing the same. The electrochemical catalyst structure may include a catalyst layer including a perovskite based oxide as an electrochemical oxygen reduction catalyst; and a modifying layer being in contact with the catalyst layer and including a transition metal oxide capable of chemical interaction with a metal of the perovskite based oxide through electron orbital hybridization.
