    Abstract: Disclosed are a method of manufacturing a carbon support for a fuel cell catalyst, a carbon support for a fuel cell catalyst manufactured according to the method, and a catalyst for a fuel cell including the same. The method may include using various organic materials containing N and various carbon supports and thus provide excellent economic feasibility. In addition, pyridinic N and pyrrolic N of doped N can be adjusted at an optimal content ratio so that the carbon support for a fuel cell catalyst manufactured and the catalyst for a fuel cell including the same have excellent electrochemical resistance and excellent electrochemical characteristic due to an increase in an electrochemically active surface area, and excellent durability due to an increase in thermal durability.
