Abstract
PURPOSE: To obtain a long-lived oxygen reductive catalyst bearing elements other than Pt and capable of lowering the reductive overvoltage of oxygen from a porphyrinic metal complex having specific structure.
CONSTITUTION: An oxygen reductive catalyst, composed of a porphyrinic metal complex having a structure of the formula (where X1, X2, X3, X4 and X5 are each a halogen atom coincidently or differently and Me is a central metal such as Co, Fe, or Mn), e.g., Co-ms-[5, 10, 15, 20]tetrakis-(penta-fluorophenyl) porphirin, is obtained. The compound of the formula, having Co as the central metal exhibits higher activity, and F as halogen atom exhibits the highest activity. The oxygen reductive catalyst is used in cathodic electrode, and electrolyte used for the catalyst as the electrode includes sulfuric acid for acid, an Na2SO4 aqueous solution, for example, for neutral, and a KOH aqueous solution, for example, for basic. Also, when the catalyst is supported on the electrode, the electrode is dipped in a solution of the catalyst in a solvent, for example.
