Summary: One of the significant drawbacks of Direct Methanol Fuel Cells is high overpotential for the methanol oxidation reaction, as well as CO poisoning of Pt. In this study, electrocatalysts with suitable properties and outstanding performance have been developed by synthesizing PtCu and PtCuRu materials through a simple and scalable process. The materials were further treated to enhance their surface with a higher density of active sites and surface defects. The trimetallic catalysts showed a substantial reduction in CO electrooxidation and improved methanol oxidation performance.

Summary: Direct-methanol fuel cell (DMFC) systems are relatively simple, but accurately controlling the mixture of methanol and water is a key challenge. Computational fluid dynamics can provide fundamental understanding of this. This paper presents a three-dimensional, steady-state, two-phase, multi-component and non-isothermal DMFC model that can account for various transport phenomena. The model is validated against experimental measurements and used to study the impact of volume porosity and capillary pressure on performance.

Summary: This review examines the applications of activated carbonaceous material as supports for electrocatalysts in fuel cells and discusses the various techniques used to produce these carbon materials. The paper also provides an overview of the architecture and operation principles of fuel cells, as well as the importance of support materials and their characteristics. However, the long-term instability of carbon-supported electrocatalysts due to corrosion remains a challenge, and the incorporation of nanostructured carbon supports in fuel cells still has limitations in terms of cost-effectiveness and efficiency.

Summary: This experimental study investigated the performance of passive direct methanol fuel cells (DMFC) with respect to the activation of the membrane electrode assembly (MEA), methanol concentration, bolt tightening torque, and stability of the fuel cell stack. The results showed that the fuel cell performance was enhanced with increasing methanol concentration from 1 M to 5 M and then decreased. Furthermore, increasing the bolt torque from 4 N-m to 7 N-m improved the fuel cell performance, but exceeding the optimal torque led to a decrease in performance.

Summary: In this study, the effect of a porous coating configuration on the suppression of hypersonic boundary-layer transition under thermochemical nonequilibrium (TCNE) is examined using linear stability theory (LST) and direct numerical simulation (DNS). The results show that the porous coating destabilizes the second mode instability and shifts it upstream under the TCNE effect, and this effect is similar under both the calorically perfect gas (CPG) and TCNE assumptions. The acoustic attenuation of the instability within the cavity is minimally affected by the TCNE effect, and the admittance models in LST can accurately predict the trend of disturbance growth in DNS.

Summary: In this study, the influence of cooling air velocity, regeneration hot water temperature, and adsorption/regeneration cycle time on a heat exchanger coated with aluminophosphate zeolite for desiccant dehumidification was experimentally investigated. The results showed that the minimum humidity of the adsorption outlet air decreased with an increase in the cooling air velocity and adsorption/desorption time. However, the maximum time-averaged amount of dehumidification appeared at an appropriate cycle time, and increasing the cooling air velocity had a positive impact on both the momentary observed minimum humidity and time-averaged amount of dehumidification. The temperature of the hot water also contributed to the increase in the time-averaged amount of dehumidification.

Summary: A study was conducted on a green hydrogen system for powering an office building in the Sharjah emirate, United Arab Emirates. A hybrid green hydrogen energy system was compared to a standard hybrid system, and both systems met the power requirements of the office building. The cost of energy was similar for both systems, but the operational and replacement costs were higher for the basic system compared to the green hydrogen system. The green hydrogen system also had a significantly lower carbon footprint compared to the basic system, reducing carbon dioxide emissions by a ratio of 4.6.

Summary: The effects of operating parameters and electrode types on hydrogen gas production through electrolysis were investigated in a PEM electrolyzer. Various parameters including power supply, feed water flow rate, water temperature, and anode electrocatalyst type were varied. The best performance was observed with a flow rate of 2 mL/min and a temperature of 70 degrees C, using a membrane electrode assembly with a 3.0 mg/cm2 IrRuOx catalyst at the anode side. Optimal energy consumption was achieved at a current density of around 200 mA/cm2, with voltaic and energy efficiencies of 85% and 67.5% respectively. These findings highlight the importance of optimizing operating parameters to enhance the performance and reduce the costs of PEM electrolyzers.

Summary: CO2 capture from air via temperature swing adsorption (TSA) and the use of low-volatility polyamine-loaded silica in double-pipe heat exchangers can achieve rough enrichment of CO2. A double-step adsorption process can simultaneously increase CO2 adsorption and recovery. This method can produce a product gas with a CO2 concentration 100 times higher than the raw gas, with a recovery ratio of 60%. Therefore, the reflux step significantly enhances CO2 capture via adsorption from elevated-CO2-concentration recirculating gas.

Summary: This article presents the results of a systematic study on the electrochemical performance and mechanical changes in two types of commercial batteries with different anode chemistry. The study reveals that the swelling of anode layers in batteries with silicon-based components causes deformations in the jelly roll structure, but the presence of a small percentage of silicon does not significantly impact the cycling performance of the cells within the relevant state-of-health range for electric vehicles (EVs). The research suggests that there is room for improving the cell capacities by increasing the silicon loading in composite anodes to meet the increasing demands on EVs.

Summary: By coupling electrochemical testing to operando synchrotron based X-ray absorption and powder diffraction experiments, blended positive electrodes consisting of LiMn2O4 spinel (LMO) and layered LiNi0.5Mn0.3Co0.2O2 (NMC) were studied to understand their redox mechanism. It was found that blending NMC with LMO can enhance energy density at high rates, with the blend containing 25% LMO showing the best performance. Testing with a special electrochemical setup revealed that the effective current load on each blend component can vary significantly from the nominal rate and also changes with SoC. Operando studies allowed monitoring of the oxidation state evolution and changes in crystal structure, in line with the expected behavior of individual components considering their electrochemical current loads.
