Abstract
The present disclosure relates to a method for preparing a catalyst for a fuel cell, a catalyst for a fuel cell and a fuel cell including the same. More specifically, the catalyst for a fuel cell according to the present disclosure, wherein ruthenium chalcogenide including the 1T phase exists as single-walled nanotubes, can reduce manufacturing cost by exhibiting superior catalytic activity so as to replace the existing platinum catalyst and can significantly improve stability.
