摘要：

Catalytic nano-clusters of platinum are deposited by high density plasma sputtering into porous carbon gas diffusion layers for low temperature fuel cell electrodes. This plasma process leads to the deposition of catalyst onto the surface of the substrate and assists its diffusion in the carbon layer. In this work, we discuss the influence of the plasma parameters on this diffusion of platinum. (c) 2005 Elsevier B.V. All rights reserved.
