Pourquoi c'est important pour les matériaux
Two competing electrolyser designs have completely different material profiles. Alkaline needs nickel and steel; PEM needs platinum and iridium. Which one wins determines which metal becomes scarce.

Copper
The reddish metal that carries electricity better than anything except silver, and which humans have been smelting…
Iridium
The most corrosion-resistant metal known, and the second densest — a litre of it weighs about 22.5 kilograms.
Nickel
A silvery metal that resists rust, which is why it goes into stainless steel — and, more recently, into the cathodes…
Platinum
A dense, unreactive metal that speeds up chemical reactions without being consumed by them.
Iron & Steel
Iron with a little carbon in it, and the most-produced manufactured material on the planet.
Titanium
A metal as strong as steel at about half the weight, which does not corrode in seawater or in the human body.
