Frequently Asked Questions

Where is platinum used in hydrogen systems?

It is especially important in PEM fuel-cell catalyst layers and at the hydrogen-producing cathode of PEM electrolyzers.

Is platinum the main PGM in the PEM electrolyzer anode?

No. Current PEM electrolyzer anodes depend much more heavily on iridium; platinum is associated primarily with the cathode hydrogen-evolution reaction.

Do compressed-hydrogen tanks require platinum?

Not generally. Bulk compressed storage is primarily a pressure-vessel and materials-engineering problem rather than a platinum-catalyst application.

Can platinum from fuel cells and electrolyzers be recycled?

Yes. Manufacturing scrap and end-of-life PGM-containing components can become secondary material sources.

Does this site explain hydrogen fueling or storage procedures?

No. Hydrogen handling, storage, compression, fueling and emergency procedures are deliberately excluded.
