Abstract:
1. An electrocatalyst for an electrochemical cell, comprising: a metal catalyst which contains metal having a metal oxidation potential of 0.5V or higher to 1.5V or lower, the metal being directly involved in an electrode reaction; and an aromatic heterocyclic compound which has a six-membered ring structure containing a heteroatom, the heteroatom having a metal coordination capacity that is not directly involved in the electrode reaction, wherein the aromatic heterocyclic compound is heterogeneously adsorbed and coordinated on a surface of the metal catalyst while interposing the heteroatom therebetween, and wherein the aromatic heterocyclic compound coordinated in a ratio of 0.1 to 1.5 nmol/cm
