The use of titanium mesh-supported gold and silver anodes in direct borohydride fuel cells (DBFCs) is reported. The anodes were prepared by either thermal decomposition or electrochemical deposition and were characterised by scanning electron microscopy and X-ray diffraction analyses. The performance of the mesh electrodes was compared with that for carbon-supported electrodes. The mesh anodes gave current densities, for borohydride oxidation, up to 50% greater and cell power densities up to 20% greater than those obtained with carbon-supported anodes. The effects of catalyst loading and fuel cell operating conditions are also reported. Electrode stability was examined over a prolonged period. © Springer Science+Business Media B.V. 2006.
