Platinum in Energy & Hydrogen Systems: The Whole Picture
Where platinum appears across hydrogen production, fuel cells, energy conversion, recycling and supply chains.
What this topic covers
Where platinum appears across hydrogen production, fuel cells, energy conversion, recycling and supply chains.
Core energy-system ideas
Platinum is not a universal ingredient in every hydrogen technology; its importance is concentrated in selected electrochemical and catalytic components.
In proton-exchange-membrane fuel cells, platinum-based catalyst layers support the hydrogen oxidation and oxygen reduction reactions.
In PEM electrolysis, platinum is used on the hydrogen-evolving cathode while other PGMs, especially iridium, are more important on the oxygen-evolving anode.
Important tradeoffs
Fuel cells, electrolyzers, storage and delivery equipment should be separated when estimating material demand.
Material and performance evidence
Energy-system performance depends on catalysts plus membranes, transport, power electronics, thermal systems and duty cycle.
Lifecycle perspective
Hydrogen and pressurized equipment require professional engineering and operating controls.
