Russian scientists recently introduced a new method for fabricating film solid electrolytes for use in contemporary fuel cells.
Alternative energy technologies may benefit from the progress. Hydrogen is one potential sustainable energy source in the future. Many laboratories all around the world are hard at work developing hydrogen energy technologies.
The most quickly developing type of such devices is solid oxide fuel cells, which are electrochemical power generators with excellent efficiency. The high temperatures required to operate these fuel cells are the primary barrier to their wider use.
To meet the demands of today’s medium-temperature solid oxide fuel cells, researchers from IGIC RAS and their IPChE RAS counterparts have developed a new method of employing high-resolution microextrusion printing to manufacture planar solid electrolytes based on cerium and samarium oxides.
The excellent electrical conductivity of the resulting coatings makes them attractive candidates as solid electrolytes for fuel cells operating between 400 and 600 degrees Celsius.
