Abstract Epoxy resins are widely utilized in electronics, electrical components, and communication equipment for polymer‐based wave‐transparent composites. However, the dielectric constant ( ε ) loss (tan δ of common epoxy relatively high 3.8–4.2; tan 0.018–0.025), corresponding impact resistance is poor. Thus, it cannot meet requirements advanced microelectronic materials. And prepared by filling inorganic fillers difficult to combine low with good machining performance. The intrinsic can...
Perfluorosulfonic acid (PFSA) is widely used as the membrane material for proton-exchange fuel cells, and its mechanical properties directly affect stability life of internal structure proton exchange membrane. In present research, behaviors hydrated membranes are investigated through macro-mechanical experiments nano-simulation. The commercial products Nafion® 117 212 tensile testing samples, latter manifests a larger swelling ratio, smaller linear-elastic region, higher Young's modulus at...
For the requirement of complex dynamic performance for fuel cell vehicle (FCV), wide operation range and rapid response ability are essential to electric air compressor, which limited by output torque permanent magnet synchronous motor (PMSM) commonly used in FCV. The purpose this study is improve stators its capacity PMSM using mathematical model, multiobjective optimization, experimental validation. First, a model speed regulation ultrahigh-speed established, provides basis Taguchi legal...
Proton exchange membrane fuel cell (PEMFC) is significant and favorable to the long-range short refueling time in vehicle industry. However, non-uniform distribution of gas flow supply, particularly stack neglected electrochemical model for PEMFC performance optimization. The purpose this study break through limitation establish an optimized model, with porous media methods considering different compression layer (GDL). numerical models are validated by experimentation a practical stack. For...
Electronic fareboxes integrated with Automatic Vehicle Location (AVL) systems can provide location-stamped records to infer passenger boarding at individual stops. However, bus loads and Origin-Destination (OD) flows, which are useful for route planning, design, real-time controls, cannot be derived directly from farebox data. Recently, Wi-Fi sensors have been used collect OD flow information. But the data insufficient capture variation of demand across trips. In this study, we propose a...
The control strategy of the gas supply subsystem is very important to ensure performance and stability fuel cell system. However, due inherent nonlinear characteristics subsystem, traditional mainly based on proportional integral (PI) control, which has disadvantages large limitation, error, limited immunity, inconsistent performance, seriously affects its effectiveness. In order overcome these challenges, this paper proposes an optimal method for air subsystems active disturbance rejection...
