Abstract

Hydrogen electrosorption is studied on 3D porous carbon electrodes fabricated by interferometric lithography. Mixed acetonitrile/water solutions provided a route to electrodeposit Pd nanoparticles homogeneously throughout the structures. These monoliths exhibit hydrogen electrosorption profiles typical for limited volume electrodes and consequently are promising candidates for micro-hydrogen based fuel cells. In contrast, aqueous solutions resulted in asymmetric Pd depositions due to the hydrophobic nature of the carbon electrode and its unique 3D porous structure. These electrodes exhibited unusual nonlimiting hydrogen electrosorption profiles.
