Почему это важно для материаловедения
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.
Из чего состоит
Все материалы →| Материал | Что он делает здесь | Значимость |
|---|---|---|
| Copper критически важный | Power delivery at very high current | Определение |
| Iridium критически важный | PEM anode catalyst | Определение |
| Nickel критически важный | Alkaline electrolyser electrodes | Определение |
| Platinum критически важный | PEM cathode catalyst and fuel cells | Определение |
| Iron & Steel | Stacks, vessels and piping | Важно |
| Titanium критически важный | PEM bipolar plates | Важно |
| Scandium критически важный | Solid-oxide cell electrolyte | Настоящее время |
| Yttrium критически важный | Solid-oxide cell electrolyte | Настоящее время |
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.
