Nickel catalysts are not as good as their noble metal counterparts for hydrogen oxidation in alkaline environments. They only have 1-2% of their activity. This is a problem because scientists don't fully understand why. But recent research sheds some light on this issue. The study looked at how different anions, like OH - , Br - , Cl - , and SCN - , affect t...
Fuel cells are a big deal in the world of clean energy. They convert chemical energy into electrical energy. One type, called thin-film solid oxide fuel cells, has been getting a lot of attention. These cells have a special layer called the anode functional layer. This layer is super important for the cell's performance, especially when it's working at low temperatur...
Imagine trying to make a super-efficient car that runs on fuel cells. It's a big dream, and to achieve it, scientists have to understand every tiny part of how these fuel cells work. These fuel cells, called Solid Oxide Fuel Cells (SOFCs), need to be better and last longer. Lots of money and time are spent trying to make SOFCs better through experim...
You know how fuel cells use something called a catalyst to make energy? Usually, they use something called a platinum catalyst. But scientists are looking for something better. One option is something called an Fe-N-C catalyst. It's promising, but it doesn't last long enough. So, some smart researchers decided to change things up. They took the Fe-N-C catalyst and tu...
Imagine a world where wastewater treatment plants can generate electricity while cleaning up our water supplies. That's the promise of microbial fuel cells (MFCs), a fascinating piece of green technology. As we face global water shortages and energy crises, finding eco-friendly solutions is more crucial than ever. MFCs work by using microorganisms as natural catalys...
Imagine a world where carbon dioxide, the main culprit behind climate change, is transformed into a clean energy source. Sounds like science fiction, right? Well, researchers from Tokyo Metropolitan University have made it a reality. They've developed an innovative electrochemical cell that can efficiently convert captured carbon dioxide into formate, a green fuel th...
