16. The channels in PDMS or made of SU-8 were 2 mm wide and were 200 or 50 μm thick. The interelectrode distance was 1 mm. The electrodes were 1.7 cm long and 500 μm wide.

18. The contact of a V(II) solution with a metallic surface (for example, Au) generates bubbles of gas on the surface.
19. The electrode reaction of the V/V(IV) system at graphite electrode changes from irreversible to quasi-reversible on increasing the sulfuric acid concentration from 1 to 6 M (∼30%); the redox potential of the V(II)/ V(III) system does not vary over this range [Kaneko, H.; Nozaki, K.; Wada, Y.; Aoki, T.; Negishi, A.; Kamimoto, M. Electrochim. Acta 1991, 36, 1191].
20. The solutions in the channels were either pumped by syringe pump or injected by gravity. In the experiments we describe, the cell was operated in a mode in which the solutions of redox components were discarded after use; we have not demonstrated coupled regeneration of the fuels [Bergens, S. H.; Gorman, C. B.; Palmore, G. T. R.; Whitesides, G. M. Science 1994, 265, 1418].

25. Comparing the volumetric power density of this system with an AA battery is instructive. A battery of this size delivers approximately 2.8 Ah and has a volume of 14 mL. This membraneless fuel cell would require 2 L of each fuel to deliver the same power. If fuel consumption were 100% efficient, the cell would still require 200 mL of each fuel to deliver comparable power.
