Title: PLATINUM LOADED SUBSTRATE FOR A FUEL CELL AND METHOD FOR PRODUCING SAME
Abstract:
A method of depositing platinum onto a support is disclosed. This method is based on a combination of two processes: electrochemical and electroless deposition, using a chemical bath containing a platinum source and agents that trigger nucleation and buffer the solution. This method is capable of producing a catalyst having a gravimetric current density of at least approximately 0.8 mA/cm2 per ?g of platinum per cm2 at cell voltage of 0.9V/RHE for oxygen reduction reaction.
