Outline
To systematically review recent advances in mesoporous carbon materials as novel catalyst supports for proton exchange membrane fuel cells, this paper outlines synthetic strategies including templating, sol-gel, chemical vapor deposition, and electrospinning, and elucidates how the microstructures of diverse supports such as ordered mesoporous carbons, hierarchical porous carbons, and heteroatom-doped mesoporous carbons govern catalytic performance. The research results indicate that the regular pore architecture, high specific surface area, and excellent chemical stability of mesoporous carbons significantly enhance Pt dispersion and oxygen transport efficiency. Future research will focus on 4 key directions: enhancing intrinsic stability, enabling low-cost scalable synthesis, achieving precise structural design, and optimizing synergy with low-Pt and non-Pt catalysts, thereby accelerating their engineering application.
