Making Fuel Cells cheap enough for mainstream use: can Cobalt nanoparticles replace Platinum as catalysts?
Platinum is scarce and expensive. Tsun-Kong Sham and Ali Feizabadi at Western University describe their cutting edge research that aims to replace much of the platinum. Their cobalt-doped palladium-platinum core-shell solution is much cheaper, yet maintains the performance and durability of the original. That’s why it has the potential to revolutionise fuel cell technology, say the authors.
