Comparison of electron transfer from reduced ferredoxin to FAD and a gold electrode, FUEL 192-Conversion of a plant chloroplast to a biological fuel cell, Atomic layer deposition of yttria-stabilized zirconia for solid oxide fuel cells. A CAD integration framework for designing devices with atomic scale resolution. The devices were constructed by micro-molding and thermal assembly of 85/15 poly(L-lactide-co-glycolide) sheets. MD simulations of the interaction of ferredoxin and protonated pyridine within a water solvation box indicate that the protonated pyridine does strongly orient the ferredoxin, favoring electron transfer as compared to a bare gold surface, where we speculate the orientation of the ferredoxin may be more random.

Active water management for proton exchange membrane fuel cells using an integrated electroosmotic pump. We attribute the superior cell performance to significant reduction in both the ohmic and the polarization losses due to the combined effects of employing an ultrathin film electrolyte, enhancement of effective area by 3-D architecture, and superior catalytic activity by the ceria-based interlayer at the cathode.
