“…There is significant interest in the development of portablepower systems for applications ranging from satellite/backup power generation [8][9][10] to transportation systems [11][12][13] to portable electronics [14][15][16][17]. For portable-power systems employing hydrogen-driven PEM fuel cells, multiple schemes for safe and efficient storage of hydrogen have been investigated, including carbon [18][19][20] and zeolite sponges [21,22] as well as metal-hydride systems [23,24].…”

“…For instance, Li-ion batteries can permanently lose 35% of energy capacity over the period of 12 months if exposed to 40 °C ( Table 5 ). 154 In this context, the higher energy density of methanol fuel provides an opportunity for DMFCs in the portable power sector. As discussed in the introduction, the theoretical specifi c energy density of methanol is signifi cantly higher than the energy density of advanced Li-ion batteries, but a fair comparison of complete DMFC systems versus Li-ion batteries shows a much tighter race.…”

The direct methanol fuel cell (DMFC) enables the direct conversion of the chemical energy stored in liquid methanol fuel to electrical energy, with water and carbon dioxide as by-products. Compared to the more well-known hydrogen fueled polymer electrolyte membrane fuel cells (H 2 -PEMFCs), DMFCs present several intriguing advantages as well as a number of challenges.This review examines the technological, environmental, and policy aspects of direct methanol fuel cells (DMFCs). The DMFC enables the direct conversion of the chemical energy stored in liquid methanol fuel to electrical energy, with water and carbon dioxide as byproducts.Compared to the more well-known hydrogen fueled PEMFCs, DMFCs present several intriguing advantages as well as a number of challenges. Factors impeding DMFC commercialization include the typically lower effi ciency and power density, as well as the higher cost of DMFCs compared to H 2 -based fuel cells. Because of these issues, it is likely that DMFC technology will fi rst be commercialized for small portable power applications (e.g., the displacement of batteries in consumer electronic applications), where the shorter product lifetimes ( ∼ 1-2 yrs for a battery versus 8-15 yrs for a car) and the much higher price points ( ∼ $10/W for a laptop battery vs. ∼ $0.05/W for a vehicle engine) provide a more attractive entry point. While such applications are not likely to signifi cantly impact the global energy sustainability picture, they provide an important initial market for fuel cell technology. As such, in this review, we provide an overview of recent research and the challenges to the development of DMFCs for both the portable (shorter-term) and transport (longer-term) sectors.

In this work, we present a self-powered electronic reader (e-reader) for point-of-care diagnostics based on the use of a fuel cell (FC) which works as a power source and as a sensor. The self-powered e-reader extracts the energy from the FC to supply the electronic components concomitantly, while performing the detection of the fuel concentration. The designed electronics rely on straightforward standards for low power consumption, resulting in a robust and low power device without needing an external power source. Besides, the custom electronic instrumentation platform can process and display fuel concentration without requiring any type of laboratory equipment. In this study, we present the electronics system in detail and describe all modules that make up the system. Furthermore, we validate the device’s operation with different emulated FCs and sensors presented in the literature. The e-reader can be adjusted to numerous current ranges up to 3 mA, with a 13 nA resolution and an uncertainty of 1.8%. Besides, it only consumes 900 µW in the low power mode of operation, and it can operate with a minimum voltage of 330 mV. This concept can be extended to a wide range of fields, from biomedical to environmental applications.
