This paper presents Neural Network (NN) model of Polymer Electrolyte Membran (PEM) Fuel Cell for electric vehicle. The NN model simplifies the conventional model that considered thermodynamics, electrochemistry, hydrodynamics and mass transfer theory. The NN has a multilayer feed forward network structure and is trained using a back propagation learning rule. The NN model is used to predict the...

Abstract Nanocomposite solid polymer electrolytes are considered as a promising strategy for solid‐state lithium metal batteries (SSLMBs). However, the randomly dispersed fillers in matrix with limited Li + transference number and insufficient ionic conductivity severely sacrifice ion transport capacity, thus restricting their practical application. To tackle these issues, magnetic field‐assist...

The use of Cs0.5H0.5PW12O40 insoluble salt as a superacid promoter in the catalyst layer of a polymer electrolyte membrane fuel cell (PEMFC) has been investigated. An increase of performance has been recorded at intermediate temperatures (110–130 °C) and under low relative humidity (R.H.). The promoter appears to mitigate the ionomer dry-out effects in the catalytic layer and produces an increa...

A composite electrolyte based on a garnet (LLZO) and polyester-based co-polymer (80:20 ε-caprolactone (CL)-trimethylene carbonate, PCL-PTMC with LiTFSI salt) is prepared. Integrating the merits of both ceramic electrolytes expected to address poor ionic conductivity high interfacial resistance in solid-state lithium-ion batteries. The 80 wt % LLZO 20 polymer (PCL-PTMC lithium bis(trifluorometha...

We study the Soret effect of charged polystyrene particles as a function of temperature and electrolyte composition. As a main result we find that the Soret coefficient is determined by charge effects, and that non-ionic contributions are small. In view of the well-known electric-double layer interactions, our thermal field-flow fractionation data lead us to the conclusion that the Soret effect...
