Machine learning method speeds up discovery of green energy materials

Researchers ditch “trial and error” and turn to machine learning

23-Jan-2024 - Researchers at Kyushu University, in collaboration with Osaka University and the Fine Ceramics Center, have developed a framework that uses machine learning to speed up the discovery of materials for green energy technology. Using the new approach, the researchers identified and successfully ...

Novel multi-proton carrier complex as efficient proton conductor at high temperatures

Researchers develop a highly symmetric ruthenium (III) complex with six imidazole-imidazolate groups for efficient high-temperature proton conduction in fuel cells

21-Jul-2022 - As the world is moving towards more environment-friendly and sustainable sources of energy, fuel cells are receiving a lot of attention. The main advantage of fuel cells is that they use hydrogen, a clean fuel, and produce only water as a by-product while generating electricity. This new and ...

What Do Spiders Have in Common with Batteries?

Spider silk inspires new class of functional synthetic polymers: Conducting protein-based material could be used in fuel cells, batteries or act as sensor

14-Aug-2020 - Synthetic polymers have changed the world around us, and it would be hard to imagine a world without them. However, they do have their problems. It is for instance hard from a synthetic point of view to precisely control their molecular structure. This makes it harder to finely tune some of their ...

New high proton conductors with inherently oxygen deficient layers open sustainable future

Proton-conducting materials provide a number of advantages

09-Jul-2020 - Over the past few years, fuel cells have become a focal point of research in eco-friendly technology because of their superior abilities to store and produce renewable energy and clean fuel. A typical type of fuel cell gaining ground is the proton-conducting fuel cell, which is primarily made of ...

Unveiling distribution of defects in proton conductors

21-Oct-2015 - Solid oxide fuel cells (SOFC), recently used as a power source for households in Japan, have several drawbacks such as high-cost, material degradation and long start-up time derived from high operating temperatures up to 750°C. Lowering the operating temperature to an "intermediate" range of ...
