Special Issue Information

Dear Colleagues,

The field of biofuel cells has grown significantly in recent times, partly spurred by hopes of becoming the power source of choice in star applications such as implants or small and disposable electronic devices. Despite the huge research efforts made towards sustaining higher power outputs longer, these appears to be limited to the µW·cm-2–mW·cm-2 range. Although this is certainly enough to run present-day low-power electronics, biofuel cells are still too costly to be considered a competitive alternative to other power sources, regardless of their application.

This Special Issue represents an opportunity to showcase the latest advances in the area of biofuel cells, from fundamental aspects related to bio-electrocatalysis, including the engineering of better biocatalysts, to the wiring of the latter to electrodes to increase electron transfer rates, through to developments in low-power electronics and integration technologies. Regarding applications, this Special Issue is particularly open to contributions featuring sensing applications of biofuel cells, which may represent more suitable applications than power sources alone. The best examples are perhaps self-powered sensors, where the biofuel cell output (power, current or potential) is proportional to an analyte concentration. This includes toxicity sensors based on inhibition or enhancement of power output in the presence of target analytes.

I would like to invite you to participate in this Special Issue on biofuel cells. Both original research papers and review articles are welcome.

This work presents a hardware/software data acquisition system developed for monitoring the temperature in real time of the cells in Air-Cooled Polymer Electrolyte Fuel Cells (AC-PEFC). These fuel cells are of great interest because they can carry out, in a single operation, the processes of oxidation and refrigeration. This allows reduction of weight, volume, cost and complexity of the control system in the AC-PEFC. In this type of PEFC (and in general in any PEFC), the reliable monitoring of temperature along the entire surface of the stack is fundamental, since a suitable temperature and a regular distribution thereof, are key for a better performance of the stack and a longer lifetime under the best operating conditions. The developed data acquisition (DAQ) system can perform non-intrusive temperature measurements of each individual cell of an AC-PEFC stack of any power (from watts to kilowatts). The stack power is related to the temperature gradient; i.e., a higher power corresponds to a higher stack surface, and consequently higher temperature difference between the coldest and the hottest point. The developed DAQ system has been implemented with the low-cost open-source platform Arduino, and it is completed with a modular virtual instrument that has been developed using NI LabVIEW. Temperature vs time evolution of all the cells of an AC-PEFC both together and individually can be registered and supervised. The paper explains comprehensively the developed DAQ system together with experimental results that demonstrate the suitability of the system. Full article
