Generating electricity from renewable sources will soon become as easy as putting a brush and a tube in a tub of wastewater. A carbon fiber, bottle-brush anode developed by Penn State researchers will ...

The top image shows the construction of the ZnS/CuS anode and carbon fiber cathode used in the experiment. The bottom image illustrates the performance of the ZnS/CuS anode/cathode construction ...

The anode is the negative electrode of the fuel cell. This electrode is in contact with the proton exchange membrane (PEM) that is coated with a platinum-based catalyst. The catalyst dissociates the ...

Solid-state batteries are safer and less-flammable than conventional EV batteries, so why haven't automakers made the switch ...

Fuel cells convert the chemical energy from a fuel into electricity through a chemical reaction of positively charged hydrogen ions with oxygen or another oxidizing agent. They differ from batteries ...

Cathodes play a dominant role in defining cell energy density, and also make up a significant proportion of cell costs, due to the use of high-cost metals such as cobalt, nickel and lithium. Standard ...
