Direct methanol fuel cell anode catalyst characteristic current density

Table 4.3. Effect of three-dimensional support on the PtRu catalyst characteristics produced by galvanostatic elechodeposition from a colloidal media containing 25 vol% Triton X-lOOhsopropanol (1 4 v/v ratio) and 75 vol% aqueous phase (with 2.5x10 M H2PtCl6 and (NH4)2RuCl6 each). Deposition current density 20 A m, 120 min, 341 K [218]. RVC = reticulated viheous carbon, UGF = graphite felt (uncompressed).
