The design and preparation of ORR electrocatalysts with low cost, high catalytic activity and high stability are of crucial importance to the practical application of fuel cells. Carbon aerogels (CAs) have the advantages of controllable pore structure, high specific surface area, high conductivity and large pore volume, and these characters allow it a potential candidate for fuel cell ORR electrocatalyst carrier. In this review, the recent progress on CAs as fuel cell catalyst carrier were reviewed. Firstly, the species of carbon aerogels and methods of supporting catalysts were simplely introduced, and then the research progress on precious metal catalysts supported on CA, especially Pt, the non-noble metal catalysts supported on CA and non-metal doping CA catalysts were discussed. In addition, the challenges and development direction in the future were summarized.
