Abstract

A 3D-printed microfluidic fuel cell is presented. Fused deposition modeling is used to build a microchannel with a 0.015 cm<sup>2</sup> cross-sectional area for stable colaminar flow conditions. A new 3D-Printed cell fed by glycerol displays a power density of 175 mW cm<sup>-2</sup> at 0.9 V and 1.8 V of open-circuit voltage.
