Abstract: A numerical method is proposed to study load and the environment couple effect during the service of a concrete bridge. By studying the corrosion process of reinforcement bars, the strain of the bars is decomposed into two ...

Abstract: A series of Y0.2 Zrx Ce0.8−x O1.9 compounds (0 ≤ x ≤ 0.6) had been prepared by the modified sol-gel method and characterized by powder X-ray diffraction, thermo-gravimetric analysis, four-probe ...

Abstract: A simple, low-cost testing method is proposed for fuel cell hardware development. A perforated aluminum foil with an array of small holes covered with carbon paper or cloth replaces the membrane ...

Abstract: Methanol crossover largely affects the efficiency of power generation in the direct methanol fuel cell. As the methanol crosses over through the membrane, the methanol oxidizes at the cathode, ...

Abstract: The flow-field design of direct methanol fuel cells (DMFCs) is an important subject about DMFC performance. Flow fields play an important role in the ability to transport fuel and drive out ...

Abstract: To cope with the phenomenon of moisture imbalances in subgrades due to excavation, the resistivity of different excavation subgrades (deep excavation section, shallow excavation section, and cut-and-fill transition section) ...

Abstract: The performances of direct methanol fuel cells are largely dependent on the methanol crossover, while the amount of methanol crossover is reported to strongly rely on membrane materials and ...

Abstract: In this study, an innovative planar stack design employing graphite plate with bipolar structure on the same side to replace current stainless steel is investigated. The design, fabrication, and ...

Abstract: Nonthermal plasma (NTP) is a promising technology for the decomposition of chlorobenzene (CB), but many conditions will affect the performance of NTP. The effects of gas temperature, relative humidity, oxygen content, ...
