The metal vapor synthesis (MVS) method has been used to prepare Ag_n/C fuel cell elec. trode catalysts with different Ag contents. The results of XRD and TEM measure ments showed that as Ag content increased the particle size of Ag_n clusters increased. XRD and XPS data indicated that Ag was mainly in zero.valence state.Ag_n/C catalysts prepared by MVS method have smaller particles of Ag_n, more narrow particle size distribution and greater catalytic activities than the Ag_n/C catalyst with the same content of Ag prepared by conventional method.
