Membraneless fuel cell created


A fuel cell that promises to be both cheaper and more efficient than existing designs has been developed by Paul Kenis of the University of Illinois at Urbana-Champaign. In a typical fuel cell, one chamber contains fuel that reacts across a porous membrane with oxygen in a second chamber, liberating electrons that provide electrical power. Kenis’s system does away with the membrane by exploiting a phenomenon known as “laminar flow”, where tiny streams of liquid behave so viscously they do not mix when squeezed past one another. That not only simplifies the cell’s design,
