Highly-dispersed platinum and platinum-based catalysts on a conductive support are commonly used as electrode materi- als in low-temperature fuel cells, particularly the hydrogen PEMFC and the direct methanol PEMFC. The performance and durability/stability...

and durability/stability of these catalysts strongly

depend on the characteristics of the support. Catalysts supported on

high surface area carbon black are widely used in low temperature fuel

cells. However, the corrosion of carbon black has...
