In this paper, the strategies to enhance the stability of fuel cell catalyst support are reviewed, with an emphasis on enhancing the graphitization degree (GD) of carbon support. Carbon-based materials are popular as support for O2 reduction reaction cathode catalysts owing to their high specific surface area, remarkable electronic conductivity and low cost. However, long-term operation in the harsh conditions of high acidity, high potential and extreme humidity, can easily lead to electrochemical corrosion of carbon support, thus affecting the activity and life of the catalyst. This paper reviews the judgment method of GD of carbon carrier, the influence of GD on material stability, and the strategy of enhancing the GD value.
