Lifespan of fuel cells maximized using small amount of metals

Fuel cells are a key future energy technology emerging as eco-friendly and renewable energy sources. In particular, solid oxide fuel cells composed of ceramic materials can directly convert fuels such as biomass, LNG, and ...

Magnetic electrodes increase solar cell efficiency

An international research collaborative led by the Ikerbasque researcher Luis Hueso has developed a photovoltaic cell in which magnetic materials such as electrodes are used for the first time to provide current. The journal ...

How the electrodes of lithium-air batteries become passivated

Lithium-air batteries produce power from air, and are often called lithium-oxygen batteries. They are much lighter than lithium-ion batteries due to higher energy density. Lithium-air batteries have applications including ...

Self-healing catalyst films for hydrogen production

Chemists at the Centre for Electrochemical Sciences at Ruhr-Universität Bochum have developed a catalyst with self-healing properties. Under the challenging conditions of water electrolysis for hydrogen production, the catalyst ...
