Hydrogen & platinum foundations
Where platinum actually fits, hydrogen production pathways, energy conversion and PGM roles.
Platinum where it matters · hydrogen as a system
Understand platinum's real role in energy and hydrogen systems.
Follow platinum through PEM fuel cells, PEM electrolysis, catalyst-layer manufacturing, hydrogen-energy applications, material intensity, durability, recycling and supply chains—while clearly separating those roles from storage and delivery equipment that usually does not depend on platinum.
ELECTRICITY → ELECTROLYZER → H₂ → FUEL CELL → ELECTRICITY
Platinum is important—but not everywhere hydrogen appears
PEM fuel cells
Anode/cathode reactions, MEAs, catalyst layers, supports, durability, efficiency and applications.
PEM electrolysis
Hydrogen evolution, cathode platinum, anode iridium context, MEAs, efficiency, durability and recycling.
Storage & delivery context
Compressed/liquid storage, pipelines, compression, refueling and hydrogen purity—with no claim that platinum is universally required.
Applications & manufacturing
Vehicles, heavy duty, stationary power, microgrids, catalyst layers, supports, membranes and production scale.
Circularity & planning
Recycling, PGM supply, criticality, platinum intensity, lifetime productivity, cost scenarios and supply risk.
Rebuilt to correct repetition and overstatement
The legacy WordPress site repeated fuel-cell efficiency, durability, electrolysis, hydrogen production, storage, recycling and clean-energy catalyst themes under dozens of similar titles. The replacement consolidates those search intents and makes a key distinction: platinum is central to selected PEM electrochemical components, but it is not a universal requirement for hydrogen tanks, pipelines, compressors or every hydrogen-production pathway.
Distinct from the platinum-catalyst site
The catalyst site explains platinum chemistry across industries. This site follows platinum specifically through the hydrogen-energy value chain: PEM fuel cells, PEM electrolysis, deployment, manufacturing, material intensity, recycling and critical-material planning.
