“…The ethanol feed is introduced to the anode side for a specific time (often 10 s), and to handle this timing, an electronic timer is exposed to the ethanol feed. The cathode side is interfaced with ambient air. ,,− Generally, the fixed resistor load, which is considered across the counter and working electrodes, is 200 Ω. The current that is produced at the anode side by electrochemical reactions is proportional to the concentration of ethanol. , A data logger is used to collect and connect to the PC to record the signals in real time to achieve the varied ethanol concentration (in a certain range).…”

Gas detection based on the electrochemical cells has recently been paid attention. Because of the many applications of fuel cell sensors, several investigations have been done on fuel-cell-type sensors for gas detection. In this study, the research works are categorized based on the type of the most used fuel cell sensors, such as CO, H2, methanol, and ethanol. Moreover, the manufacturing, applied technologies and the operating conditions of them, including the limit of detection, detection ranges, and response time of the fuel cells, are reviewed and discussed. Finally, according to the previous investigations that have been carried out, the gaps are introduced and evaluated to prepare beneficial suggestions for future investigations. According to the literature, humidity management using Pt–Cu/C is one of the most used manufacturing methods for improving a fuel cell sensor’s global and specific sensitivity. In addition, Nafion MEA with JM20 exhibits better detection performance of methanol sensors. Moreover, using nanotubes of multiwall carbon and nanoparticles of Pt–Pd in manufacturing shows proven improvements regarding the limit of detection and detection range for ethanol fuel cell sensors. PEFC-type sensor cells can improve the detection of CO to 0.2 ppm. Furthermore, the required targets for hydrogen fuel cell sensors in terms of safety and performance announced by the U.S. Department of Energy, for example, the response time of 1 s, are not reported in the open literature.

“…Optimization of fuel cell has become the hot spot in the energy technology field. As a novel type of miniature power sources with a unique membraneless structure, microfluidic fuel cells (MFCs) are emerging in recent years where the natural separation of anolyte and catholyte is realized by utilizing the co‐laminar flow characteristic of the reactant solutions in the microscale channels at a low Reynolds number 12‐14 . Consequently, normal cell operation is maintained with elimination of the physical membrane and membrane‐related problems.…”

Summary Reactant delivery systems with different shaped inlet reservoirs bring significant volume increase to microfluidic fuel cells (MFCs). In this work, a two‐dimensional model is constructed for the flow through type MFC with porous electrodes and systematic analyses are performed for the optimization of the reactant delivery system to reduce the volume cost and meanwhile enhance the cell performance. Corresponding results show that though reservoir is essential in the MFC system, a narrow channel with a width on the order of a few tenths of a millimeter is already enough for the reactant distribution and thus the inlet reservoir size can be greatly reduced (93.33% under the flow rate of 300 μL min−1) without sacrificing the cell performance. A high flexibility is allowed for the reactant inlet size of the reservoir in the cases with high flow rates while larger inlet size is preferred in the cases with low flow rates. Optimal inlet position locates in the section close to the current collectors in the ohmic‐loss dominated cases. Yet, it moves to the middle section of the system with the decrease of reactant concentration or flow rate as concentration loss is responsible for the major performance loss in these cases. The results could provide instructive guidance for the optimization of reactant delivery system in MFC with porous electrodes.
