The adoption rate of fuel cells has increased owing to the rising need for clean energy.
In a research that could jump-start the work on a range of technologies, including fuel cells, which are key to storing solar and wind energy, MIT researchers have found a simple way to significantly increase the lifetimes of fuel cells and other devices – changing the pH of the system.
Fuel/electrolysis cells made of materials known as solid metal oxides are in interest for several reasons. In electrolysis mode, they are very efficient at converting electricity from a renewable source into a storable fuel like hydrogen or methane. This storable fuel can be used in the fuel cell mode to generate electricity when the sun is not shining, or the wind isn’t blowing.
