Abstract:

The bipolar plate of polymer electrolyte membrane (PEM) fuel cells is responsible for reactant delivery, liquid product water removal, and mechanical stability of PEM fuel cell stacks. Bipolar plates account for 70-90% of the weight and volume and 18-28% of the production costof stacks [1]. Improving the function of the flow fields embedded in the bipolar plates can significantly impact the energy density of PEM fuel cells by improving liquid water management and reactant distribution. Researchers have modified conventional flow fields by adding baffles or partially narrowed channels as semi-o

Abstract:

The effect of turbulence on the mass transfer between a fluid and embedded small heavy inertial particles that experience surface reactions is studied. For simplicity, the surface reaction, which takes place when a gas phase reactant is converted to a gas phase product at the external surface of the particles, is unimolar and isothermal. Two effects are identified. The first effect is due to the relative velocity between the fluid and the particles, and a model for the relative velocity is presented. The second effect is due to the clustering of particles, where the mass transfer rate is inhib

Abstract:

Summary The need to better estimate the performance of hydraulically fractured wells in shale-gas formations has focused attention on the description of the non-Darcy flow in the region of the hydraulic fracture near the borehole where the converging flow may be increasingly dominated by the inertia effect. The analogy between high-rate flow in proppant-filled hydraulic fractures—best described by the Forchheimer equation—and the flow of reactants in fixed beds or granular beds in catalysis—widely described by the Ergun equation—may offer insights on how to estimate the value of the coefficien

Atomic-order surface reaction processes of reactant gases on the Si (100) and Ge (100) surfaces are reviewed.

The atomic-order amounts of reactant gases under self-limiting adsorption/reaction conditions are described using a modified Langmuir-type mechanism as a function of reactant gas partial pressure and exposure time at a specified temperature.

One of the principal challenges in the development of such vehicles is that the transition from water to flight is a power-intensive process.

The challenge in realizing MR-FCs is finding selective electrodes that can enhance oxygen reduction at the cathode, fuel oxidation at the anode while inhibiting the chemical reaction between the fuel and oxygen in the gas mixture.

The study draws on Lakoff and Johnson's theories on metaphor and Brehm and Brehm’s reactance theory.

Abstract:

Mesoscale combustor is one of the components that serves to generate heat on a micro power generator. As one of the components of a micro power generator, meso scale combustor serves to supply heat through the combustion process. The stability of the flame in the combustion chamber meso scale combustor is influenced by the temperature of the combustion chamber. One way to maintain a high temperature in the combustion chamber is to insert a flue gas stainless steel mesh resistor.. This research aims to prove the role of flue gas mesh resistors in stabilizing the flame on the meso scale combusto

Gas diffusion layers (GDLs) in proton exchange membrane fuel cells (PEMFCs) are responsible for diffusion of reactant gases into the catalyst layers, current collection and the removal of produced water. An accumulation of generated liquid water within the GDL, known as flooding, impedes the supply of reactant gas and results in the increase of concentration overpotential. Therefore, understanding of oxygen transport and produced water removal characteristics is required to enhance cell performance.

Abstract:

The conversion of ethylene to propylene on MCM-41 and that doped with Ni , the latter of which was prepared using various procedures, is described. Undoped MCM-41 showed no activity for the conversion of ethylene to propylene. The catalytic activity for the conversion of ethylene to propylene on Ni -doped MCM-41 was strongly dependent on the preparation procedure of the catalyst and the reaction conditions. It was found that template ion-exchange procedure using organic base was suitable for the preparation of Ni -doped MCM-41, while the catalysts thus prepared was suffered from carbon deposit

Abstract:

With the improvement of dry gas seal efficiency in high-parameter fields, the flow pattern of gas film lubrication is complicated. Based on gas lubrication theory, the Reynolds equation of compressible gas was established with a bidirectional T-groove dry gas seal as the research object. The Reynolds equation was solved to obtain a modified turbulent film pressure distribution law that affects gas lubrication. The effectiveness of the calculation program was verified by experimental tests. The results show that with an increase in operating parameters, the turbulence effect caused the gas film

Сформулированы две краевые задачи, одна из которых описывает гетерогенный процесс диффузии реагирующего газа к внешней поверхности угольной частицы, а другая - гомогенный процесс внутри ее объема. Построены точные решения задач и выявлены некоторые закономерности изменения концентрации реагирующего газа внутри объема угольной частицы. Показано, что при небольших значениях начального радиуса угольной частицы можно объединить краевые задачи и построить их приближенное ре

Abstract:

The objective of this study is to use a new style of waved flow channel instead of the plane surface channel in the proton exchange membrane fuel cell (PEMFC). The velocity, concentration, and electrical performance with the waved flow channel in PEMFC are investigated by numerical simulations. The results show that the waved channel arises when the transport benefits through the porous layer and improves the performance of the PEMFC. This is because the waved flow channel enhances the forced convection and causes the more reactant gas flow into the gas diffusion layer (GDL). The performance w
