Description: A three-dimensional mesh for a fuel cell electrode material nanoporous palladium, ruthenium and its preparation method, using EDTA as a complexing agent, HCHO as reducing agent, by hydrothermal method step will restore PdCl2 solution or PdCl2 + RuCl3 solution into nano-catalyst particles, the catalyst particles are deposited on the titanium surface formed corresponding to the electrodes. The catalyst particles of the present invention showed a uniform spherical shape, a diameter of about 60nm, are interconnected to form a porous structure stacked crisscross three-dimensional network structure so that the structural stability of the electrode material. Electrode material prepared large surface area, with a high degree of oxidation of formic acid electrochemical activity. Especially Ru join, starting much earlier potential oxidation of formic acid. Electrode material of the present invention is a method for preparing simple, stable structure, formic acid exhibit good catalytic activity, it can be applied in a direct formic acid fuel cell.
