Electrooxidation study of methanol in a laminar flow membraneless microfluidic fuel cell-a review

Microtubular Fuel Cell with Ultrahigh Power Output per Footprint

“…During miniaturization each of the components must be redesigned, and sometimes the mechanism has to be reconsidered. [4] The energy density was always found to decrease drastically because of turbulent flow of fuel and less efficiency in the electricity collection. The methanol crossover has to be attenuated or even avoided, or otherwise it would cause two detrimental consequences: selfdischarge of methanol and drastic reduction of the cathode voltage.…”

“…However, miniaturization of DMFCs is not a simple scaling down of a large system. During miniaturization each of the components must be redesigned, and sometimes the mechanism has to be reconsidered . The energy density was always found to decrease drastically because of turbulent flow of fuel and less efficiency in the electricity collection.…”
