An Analytical Model of a Novel, Microfluidic PEM Fuel Cell Device

By Dana Barrasso and R. S. Besser


The proton exchange membrane fuel cell has not met its potential as an alternative electrical energy source, due in large part to the high cost of its platinum catalyst (1). Ultra-thin films using sputtering technology have been suggested as alternatives to conventional ionomer dispersion catalyst layers (2,3,4). Although sputtered-platinum fuel cells exhibit high performance per mass of catalyst, they have lower power densities than conventional fuel cells, and their performance is not scalable with loading (5). Another emerging fuel cell technology is direct patterning of Nafion membranes, which presents opportunities to modify the Nafion surface and create innovative fuel cell architectures. Our group has demonstrated the ability to produce high-aspect rati
