some substituted power generators are being developed one of them called mfc direct methanol fuel cell is not only that satisfying the demand of fast charging but also that providing convenience dmfc is a power generating device that directly converts the chemical energy of methanol to electrical energy the advantages for using methanol are light weight slim volume longer time easy changing fuel and lower contamination therefore methanol becomes an important option for the next generation of micro power supply system however the supported catalyst volume for fuel cell is still high presently for example the most effect of the fuel cell using methanol should be at least 2 mg cm 2 of supported catalyst volume and the cost of precious metals is still high so as to cause that the cost to develop fuel cell can not be lowered down to consumer demands so that providing a catalyst with a lower supported catalyst volume and a catalytic efficiency is the most important issue in the field of low temperature fuel cell the present invention mainly provides a new electroplating method for manufacturing a nanometer catalyst some features are mentioned as below adding glycol into the electroplating solution makes the particles of a catalyst to be diffuse averagely glycol can be a stabilizer.
