Summary: This study provides an overview of the fundamentals, principles, and evaluation factors of direct methanol fuel cells (DMFCs), and conducts a parametric investigation on a JENNY 600S DMFC. The study finds that increasing the operating temperature of the fuel cell improves its output voltage, but decreases its maximum efficiency limits.

Summary: A new water management system consisting of a superhydrophilic capillary network and evaporation wings is proposed to address the issue of oxygen starvation caused by water flooding in air-breathing DMFCs. Results show that the WMCFF-DMFC has significantly higher initial peak power density and lower decline rate compared to the conventional CCFF-DMFC, demonstrating improved performance and stability.

Summary: A methodology for designing and optimizing liquid metal fast reactors has been developed, which effectively explores the search space through sampling and local searches. The design samples are evaluated using multiphysics analysis. Two studies were conducted to demonstrate the methodology, optimizing the Westinghouse long-life core lead fast reactor and designing a competitive N-15-enriched UN-fueled long-life core LFR.

Summary: The study found that increasing the current density will raise the operating temperature, increase the generation rate of methanol vapor, and reduce concentration polarization. Meanwhile, under the condition of enlarging the open area ratio, an excessive methanol supply rate may lead to deteriorated methanol crossover rates and excessively high temperatures.

Summary: A nitrogen/sulfur codoped single iron site catalyst (Fe-N/S-C) prepared through chemical vapor deposition (CVD) showed superior catalytic activity for the oxygen reduction reaction (ORR) in alkaline media. The tuning of optimal charge distribution of Fe sites by N and S codoping and the suppression of iron-carbide-containing iron clusters formation contributed to the high performance of the catalyst. Further studies demonstrated its promising performance as a cathode catalyst in direct methanol fuel cells.

Summary: Direct dual fuel stratification (DDFS) is a promising combustion mode for improving engine performance. A DDFS engine fueled with methanol and diesel was investigated at low loads. The co-optimization of injection parameters and injector layouts of the two fuels was conducted using the NSGA-II algorithm. The results showed that the fractions, injection timings, spray angles, and injector positions significantly influenced engine performance. Optimal conditions were determined to achieve low EISFC and NOx emissions simultaneously.
