THE DOE’S GOAL OF REDUCING THE IRIDIUM (IR) LOADING TO BELOW 0.125 MG IR/CM2 CAN POTENTIALLY BE ACHIEVED BY STABILIZING THE HIGHLY ACTIVE CATALYTIC IR SITES IN ACID-STABLE METAL OXIDES AND INCREASING THE ELECTRICAL CONDUCTIVITY OF CATALYST SUPPORTS THROUGH DOPING. MOREOVER, SCALABLE, AND ECONOMICAL INTEGRATION METHODS OF THOSE MATERIALS INTO MEMBRANE ELECTRODE ASSEMBLIES AND MANUFACTURING METHODS NEED TO BE DEVELOPED.
