HYDROGEN TO ELECTRICITY

A new generation of DC/DC converters

Fuel cells play a key role in the transition to renewables in power and mobility. But the energy efficiency of these cells poses a major challenge, particularly in automotive engineering. The individual components need to be as light and small as possible, yet attain a high efficiency factor.

Fast, gentle and reliable: The Fraunhofer ILT has come up with a process tailor-made to ablate anode material from very thin copper foils at up to 1760 mm³/min. It uses a powerful USP laser to expose surfaces for electrical contacts.  (Fraunhofer ILT, Aachen, Germany.)
ULTRASHORT PULSE

More flexible battery design with ultrafast laser ablation

The ultrashort pulse laser has been known to shine whenever highly sensitive material needs to be machined quickly yet gently. The Fraunhofer ILT has investigated a quick, reliable and nondestructive method of ablating lithium-ion batteries’ anode material with an ultrashort pulsed laser beam. This ablation technique exposes electrical contact points called tabs.
