“…Amongst all, the 8-hour incubation time was ideally selected with an optical density (OD at 620 nm) of 0.73. These optimized parameters were referred from the recently published research article [32]. The ideal 8-hour incubation time exhibited higher metabolic activity and significant replication rates compared to others.…”

The development of microfluidic and nanofluidic devices is gaining remarkable attention due to the emphasis put on miniaturization of conventional energy conversion and storage processes. A microfluidic fuel cell can integrate flow of electrolytes, electrode-electrolyte interactions, and power generation in a microfluidic channel. Such microfluidic fuel cells can be categorized on the basis of electrolytes and catalysts used for power generation. In this work, for the first time, a single microfluidic fuel cell was harnessed by using different fuels like glucose, microbes and formic acid. Herein, multi-walled carbon nanotubes (MWCNT) acted as electrode material, and performance investigations were carried out separately on the same microfluidic device for three different types of fuel cells (formic acid, microbial and enzymatic). The fabricated miniaturized microfluidic device was successfully used to harvest energy in microwatts from formic acid, microbes and glucose, without any metallic catalyst. The developed microfluidic fuel cells can maintain stable open-circuit voltage, which can be used for energizing various low-power portable devices or applications.

Paper devices are cutting‐edge platforms for creating miniaturized energy conversion, storage, and sensing devices. In such devices, co‐laminar flow and embedded capillaries not only eliminate membranes and external pumps but also allow widespread application. The fabrication, optimization, and characterization of a microfluidic paper ethanol fuel cell (MPEFC) has been demonstrated in the presented study. The MPEFC uses ethanol and sodium hydroxide as fuel and sulfuric acid as electrolytes. Numerous experiments have been conducted to improve the performance of MPEFC by optimizing various electrode types such as laser‐induced graphene (LIG), Ag nano‐ink/LIG, buckypaper, Ag nano‐ink/buckypaper, and two different 3D printed conductive electrodes. Different electrolyte concentrations (NaOH‐0.25, 0.5, 1 m) have been studied to understand the impact on ion conductivity. It is observed that the developed MPEFC with multiwalled carbon nanotube ‐buckypaper as an optimized electrode, 1 M ethanol with 0.5 m NaOH as anolyte, and 1 m H2SO4 as electrolyte delivered the best performance with a current density of 1756.2 μA cm−2, and power density of 72.62 μW cm−2, at a stable open‐circuit voltage of 235 mV with Gr 1 cellulose microchannel with parallel stacked configuration. This work demonstrates the effective enhancement of the output power with inexpensive individual MPEFC.
