Polymer Electrolyte Fuel Cell Transport Mechanisms: A Universal Approach to Multilayer Two-Phase Modeling Through the General Transport Equation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A mathematical multilayer, multispecies two-phase model for polymer electrolyte fuel cells (PEFCs) is presented based on fundamental molecular theory using the general transport equation (GTE). The ...
New Insight into Developing Mathematical Models for Predicting Deformation-Dependent Lateral Earth Pressure
Publisher: American Society of Civil Engineers
Abstract: All existing mathematical models for predicting deformation-dependent lateral earth pressure assume the at-rest state as the turning point for the relationship between lateral earth pressure and soil deformation. However, ...
Inductive Effect on the Fuel Cell Cathode Impedance Spectrum at High Frequencies
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The high frequency electrochemical impedance measurements with positive imaginary components in the impedance complex plot of a polymer electrolyte fuel cell (PEFC) are attributable to the inductance ...
Stability Evaluation Model of a Tunnel Face Excavated by the Benching Method in a Soft Silty Clay Layer
Publisher: ASCE
Abstract: With the increasing construction demand for tunnels in soft silty clay layers, it is important to effectively control the face stability of a tunnel. One of the key issues for maintaining face stability is addressing how ...
Experimental Investigation on Biopolymer Strengthening of Mine Tailings
Publisher: American Society of Civil Engineers
High Pressure Steel Storage Vessels Used in Hydrogen Refueling Station
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The storage of hydrogen in a compressed gaseous form offers the simplest solution in terms of infrastructure requirements and has become the most popular and most highly developed hydrogen ...
Investigation of Deflection of a Laterally Loaded Pile and Soil Deformation Using the PIV Technique
Publisher: American Society of Civil Engineers
Reinforcing Distressed Lining Structure of Highway Tunnel with Bonded Steel Plates: Case Study
Publisher: ASCE
Abstract: Lining cracks are one of the most common distresses in in-service highway tunnels and pose severe threats to the safety of tunnel operation. Traditional methods for retrofitting distressed tunnel lining all have limitations, ...
Alkali-Activated Mortar for Tunnel-Lining Structure Repair
Publisher: American Society of Civil Engineers
Abstract: With the aging of tunnel structures, rehabilitation and repair has become an increasingly important part of tunnel maintenance. This paper investigates the use of alkali-activated mortar for tunnel-lining structure repair. ...
An Improved MRT Lattice Boltzmann Model for Calculating Anisotropic Permeability of Compressed and Uncompressed Carbon Cloth Gas Diffusion Layers Based on X-Ray Computed Micro-Tomography
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The gas diffusion layers (GDLs) in polymer proton exchange membrane fuel cells are under compression in operation. Understanding and then being able to quantify the reduced ability of GDLs to ...
