Progress on Platinum-Based Catalyst Layer Materials for H-PEMFC

The constant increase in energy demand and related environmental issues have made fuel cells an attractive technology as alternative to conventional technologies. Like any technology, face drawbacks that scientific society has been focused on improve optimize the overall technology. Thus, cost is main inhibitor for this due significantly high of materials used catalyst layers. current discussion mainly focuses fundamental electrochemical half-cell reaction hydrogen oxidation (HOR) oxygen reduction (ORR) are taking place layers consisting Platinum-based Platinum-non noble metals. For purpose, studies from literature presented analyzed by highlighting comparing variations catalytic activity within experimental ones. Furthermore, economic analysis platinum group metals (PGMs) such Platinum, Palladium Ruthenium introduced presenting trends last decade.
