Hydrogen is considered as the alternate fuel for the next generation vehicles. Thus PEM fuel cells which are used as the conversion devices from chemical energy to electrical energy have large potential in vehicle market. It uses Platinum as the catalyst, the cost and availability of Platinum is one of the major contributors to the commercialization of PEM fuel cell. onventional technologies of Pt deposition such as spraying, brushing, decal layer etc. require 0.3-0.5 mg/cm2 of catalyst on carbon support for effective catalyst utilization. The attempt to reduce the Pt loading below 0.1 mg/cm2 results in drastic degradation of performance due to low catalyst utilization. It is desired to have the high concentration of 3-5 nm Pt nano particles adjacent to the membrane as well as in contact with the carbon so as to satisfy the necessary criteria of three phase boundary. Here we use a novel sputtering method for reducing the platinum loading in PEM fuel cells
