More efficient, longer-lasting solid oxide fuel cells
More efficient, longer-lasting solid oxide fuel cells
Researchers at EPFL have developed a novel way to increase fuel-cell efficiency and lifespan, using a recirculation fan driven by a steam turbine that runs on steam-lubricated bearings. Solid oxide fuel cells, or SOFCs, are devices that produce both electricity and heat by oxidizing a fuel such as natural gas or biogas.

Scientists finally confirm a 50-year-old theory in mechanics
An experiment by EPFL researchers has confirmed a theory that has been used in mechanics for over half a century - despite never having been fully validated. The team could now use the theory in bolder and more innovative ways in their quest to develop ever better energy systems. Some theories are widely used even though they have never been experimentally validated.
