Abstract: Provided is a catalyst for an oxygen reduction reaction, including an alloy in which two metals are mixed, in which the corresponding alloy is an alloy of iridium (Ir); and silicon (Si), phosphorus (P), germanium (Ge), or arsenic (As). The corresponding catalyst for the oxygen reduction reaction may have excellent price competitiveness while exhibiting a catalytic activity which is equal to or similar to that of an existing Pt catalyst. Accordingly, when the catalyst is used, the amount of platinum catalyst having low price competitiveness may be reduced, so that a production unit cost of a system to which the corresponding catalyst is applied may be lowered.
