| Chemists develop novel catalyst with two functions Posted: 09 Jul 2014 07:50 AM PDT Chemists have made a decisive step towards more cost-efficient regenerative fuel cells and rechargeable metal-air batteries. They developed a new type of catalyst on the basis of carbon, which can facilitate two opposite reactions: electrolysis of water and combustion of hydrogen with oxygen. A catalyst of this kind might make the storage of wind and solar energy and the manufacture of cost-efficient batteries, for example for electric cars, possible.  |
| More efficient fuel cells under developement by engineers Posted: 09 Jul 2014 06:59 AM PDT Solar panels need sun. Wind turbines need wind. Society needs ways to store and dispense alternative energy. Fuel cells could do this. But their chemical reactions are not fully understood. Researchers have studied a high-efficiency solid-oxide fuel cell. They took atomic-scale 'snapshots' of the conversion process using a synchrotron. Learning why the cell worked well (its atomic defects explain its electrical efficiency) will lead to even better fuel cells -- and make alternative energy systems more practical.  |
