Heteroatom-Doped Carbon Supports with Enhanced Corrosion Resistance in Polymer Electrolyte Membrane Fuel Cells

Polymer Electrolyte Membrane Fuel Cells (PEMFC) are currently considered the most advanced fuel cell technology. However, industrial implementation of PEMFCs is strongly hindered by deficient durability, especially that carbonaceous materials commonly used to support platinum-based catalyst nanoparticles, which prone electrochemical corrosion at cathode, resulting in a serious performance loss entire cell. In attempt overcome this issue, many research groups have tried introduce heteroatoms (N, S, B, P) into carbon lattice, thus trying make electrode corrosion-resistant. Newly developed heteroatom-doped carbons were subjected tests half-cell and single-cell systems evaluate their stability. This paper reviews recent studies devoted supports for Pt-based catalysts PEMFCs. particular, an overview on N, S dopants effects provided.
