Hydrogen fuel cells last longer thanks to new technology

For efficient operation, fuel cells need an electrocatalyst that improves the electrochemical reaction in which electricity is generated.

The platinum-cobalt nanoparticle catalysts used as standard today have good catalytic properties and require only as little as necessary rare and expensive platinum.

In order for the catalyst to be used in the fuel cell, it must have a surface with very small platinum-cobalt particles in the nanometer range, which is applied to a conductive carbon carrier material.

Since the small particles and also the carbon in the fuel cell are exposed to corrosion, the cell loses efficiency and stability over time.
