Fuel cells offer an enabling alternative energy technology for the present day useful energy crisis. However, one\nof the major obstacles of fuel cells in powering motor vehicles is the enormous cost associated with the catalysts\nused in both half-reactions which are Pt and Pt-Rh, respectively, for the anodic and cathodic half-reactions. Among\nseveral strategies put forward to reduce the cost of fuel cells, lowering of the amount of platinum used and replacing\nhighly expensive platinum by low-cost catalysts are two major approaches to realize the development of fuel cell-\n \n\n\n\n\n\n\n\n\n\n\n\n\n\nviz., the oxygen reduction half reaction of the fuel cells. We present here the development and the activity of Ag/\nPolypyrrole/Montmorillonite Clay catalyst which performs equally to expensive Pt-Rh catalyst used for the oxygen\nreduction half-reaction of fuel cells. We show that this catalyst functions very similar to highly expensive Pt-Rh\ncatalyst and hence the former can be conveniently substituted for the latter in practical applications.
