Novel Catalyst Support Materials for PEM Fuel Cells: Current Status and Future Prospects
The catalyst supports exhibit great influence on the cost, performance, and durability of polymer electrolyte membrane (PEM) fuel cells. This review paper is to summarize several important kinds of novel support materials for PEM fuel cells (including direct methanol fuel cell, DMFC): nanostructured carbon materials (carbon nanotubes/carbon nanofibers, mesoporous carbon), conductive doped diamonds and nanodiamonds, conductive oxides (tin oxide/indium tin oxide, titanium oxide, tungsten oxide) and carbides (tungsten carbides). The advantages and disadvantages, the acting mechanism to promote electrocatalysis, and the strategies to improve present catalyst support materials and to search for new ones are discussed. This is expected to throw light on future development of catalyst support for PEM fuel cells.
