Challenges and opportunities in modelling of proton exchange membrane fuel cells (PEMFC)

Neural Network Modeling for Proton Exchange Membrane Fuel Cell (PEMFC)

This paper presents the artificial intelligence techniques to control a proton exchange membrane fuel cell system process using particularly a methodology of dynamic neural network. The focus of this study is to derive a non-parametric empirical model. Also it will include process variations to estimate the performance of fuel cells without extensive calculations. The ANN model has been validat...

Latest Trends and Challenges In Proton Exchange Membrane Fuel Cell (PEMFC)

The effect of inclined radial flow in proton exchange membrane fuel cells performance

Computational fluid dynamics analysis was employed to investigate the radial flow field patterns of proton exchange membrane fuel cells (PEMFC) with different channel geometries at high operating current densities. 3D, non-isothermal was used with single straight channel geometry. Our study showed that new generation of fuel cells with circle stack with the same active area and inlet area gave ...

ADynamic Spherical Agglomerate Model for Proton Exchange Membrane Fuel Cells (PEMFC)

There has been growing interest in the modelling of proton exchange membrane fuel cells (PEMFC). While some steady-state models have been proposed, literature is scarce in PEMFC two-phase dynamic models and transient studies. Typical dynamic models for the fuel cell are empirical current-voltage dynamic models. The internal transients associated with reactant and product species and other compo...

Modeling and experimental study on the sealing gasket of proton exchange membrane fuel cells

In this study cross section geometry and material of gasket in proton exchange membrane (PEM) fuel cells have been investigated to achieve optimized fuel cell in terms of energy efficiency. The role of gaskets in fuel cells is sealing of gas flow channels and preventing from combination of them. In a PEM stack, gasket with approved geometry that suffers more stress has better sealing. For this ...
