“…The dual-bridge inverter practices the B4 technique and eliminates variations in the current and voltage of DC-link capacitors. In 3P4W inverters, the AC voltage is 15% higher than in split DC-link inverters [149,150]. Hence, the three phase four-leg (3P4L) inverter shows superior performance under imbalanced and nonlinear conditions at the cost of a complicated control scheme.…”

Abstract:This study summarizes an analytical review on the comparison of three-phase static compensator (STATCOM) and active power filter (APF) inverter topologies and their control schemes using industrial standards and advanced high-power configurations. Transformerless and reduced switch count topologies are the leading technologies in power electronics that aim to reduce system cost and offer the additional benefits of small volumetric size, lightweight and compact structure, and high reliability. A detailed comparison of the topologies, control strategies and implementation structures of grid-connected high-power converters is presented. However, reducing the number of power semiconductor devices, sensors, and control circuits requires complex control strategies. This study focuses on different topological devices, namely, passive filters, shunt and hybrid filters, and STATCOMs, which are typically used for power quality improvement. Additionally, appropriate control schemes, such as sinusoidal pulse width modulation (SPWM) and space vector PWM techniques, are selected. According to recent developments in shunt APF/STATCOM inverters, simulation and experimental results prove the effectiveness of APF/STATCOM systems for harmonic mitigation based on the defined limit in IEEE-519.

A nanoporous (np) AuÀ CuÀ Pt thin-film catalyst with a fine structure and tunable composition is synthesized by using a facile method involving successive electrodeposition and dealloying. The structure, electronic state, elemental content, and active surface area of the catalyst, along with the Pt fraction, are characterized and/or determined before and after the methanol oxidation reaction (MOR) tests through electrochemical and ultrahigh vacuum analytical routines. The prepared np AuÀ CuÀ (8 % in the precursor alloy)Pt catalyst exhibits outstanding mass and specific activity toward the MOR, which is approximately six-and nine-times higher than the activity of a commercial Pt/C(40 %) counterpart, respectively. A negative 75 mV onset potential shift upon the MOR anodic scan on the np AuÀ CuÀ (8 %)Pt catalyst in comparison with Pt/C(40 %) corroborates its higher catalytic activity. Furthermore, the alloy catalyst demonstrates better durability than the Pt/C(40 %) counterpart in a three-hour constant potential test and exhibits full post-factum recovery of its cycling activity. In addition, it retains more than 60 % of its original activity after 3000 cycles of an accelerated degradation test. The outstanding performance is attributed to the specific catalyst's structure leading to a d-band upshift along with unique constituent interplay.

“…[1][2][3][4][5] This technology operates via the conversion of fuel in the chemical energy form (eg, hydrogen and alcohols) directly to electrical energy without any combustion process. The conventional battery application has its limits including the necessity to recharge with external electricity sources many times, small capacity, and narrow locality.…”

“…In addition, both alcohols are easy to handle due to less toxicity and safety for human beings (ethanol is widely used in the medical field). [1][2][3][26][27][28] There are much of researchers introduced an alternative membrane to resolving the fuel crossover problem due to the commercial Nafion membrane faced high fuel permeability issues. In addition, ethanol exists naturally leads to increase value added to use the direct methanol fuel cells (DMFCs) and direct ethanol fuel cells (DEFCs) as portable power supply.. 1,[10][11][12][13][14] However, the application of both type DAFCs are still limited due to the sluggish electro-oxidation reaction of fuel on the anodic electrode and fuel crossover issue that caused by the high permeability properties of the commercial Nafion membrane from DuPont.…”

Summary Consumption of methanol and ethanol as a fuel in the passive direct fuel cells technologies is suitable and more useful for the portable application compared with hydrogen as a preliminary fuel due to the ease of management, including design of cell, transportation, and storage. However, the cost production of commercial membrane is still far from the acceptable commercialization stage. Based to our previous works, the low cost of cross‐linked sodium alginate (SA) polymer electrolyte bio‐membrane shown the virtuous chemical, mechanical, and thermal characterization as polymer electrolyte membrane in the direct methanol fuel cells (DMFCs). This study will further the investigation of cross‐linked SA polymer electrolyte bio‐membrane performance in the passive DMFCs and the passive direct ethanol fuel cells (DEFCs). The experimental study investigates the influence of the membrane thickness, loading of catalysts, temperature, type of fuel, and fuel concentration in order to achieve the optimal working operation performances. The passive DMFCs is improved from 1.45 up to 13.5 mW cm−2 for the maximum peak of power density, which is obtained by using 0.16 mm as an optimum thick of SA bio‐membrane that shown the highest selectivity 6.31 104 S s cm−3, 4 mg cm−2 of Pt‐Ru as an optimum of anode catalyst loading, 2 mg cm−2 of Pt at the cathode, 2M of methanol as an optimum fuel concentration, and an optimum temperature at 90°C. Under the same conditions of cells, the passive DEFCs are shown to be 10.2 mW cm−2 in the maximum peak of power density with 2M ethanol. Based on our knowledge, this is the first work that reports the optimization works of performance SA‐based membrane in the passive DMFCs via experimental studies of single cells and the primary performance of passive DEFCs using the SA‐based membrane as polymer electrolyte membrane.
