PEM Electrolyzer Anode: Why Platinum Is Not the Main PGM
The oxygen-evolution side is primarily an iridium challenge rather than a platinum one.
Energy-system note: platinum matters in selected components, not everywhere hydrogen appears. Real equipment decisions require current manufacturer data, codes and qualified engineering.
What this topic covers
The oxygen-evolution side is primarily an iridium challenge rather than a platinum one.
Core energy-system ideas
PEM electrolysis requires both hydrogen-evolution and oxygen-evolution catalysts.
Platinum is associated with the cathode, while iridium dominates current anode PGM requirements.
This distinction matters when estimating platinum demand from electrolyzer deployment.
Important tradeoffs
PGM demand should therefore be tracked by metal and electrode rather than as one combined number.
Material and performance evidence
Electrolyzer efficiency, durability, electricity source, water quality and manufacturing yield affect system value.
