For the energy transition to succeed, growing amount of solar and wind power need be stored for night-time or low-wind periods. Redox flow storage offers a good way balancing out fluctuations in renewable energies is considered promising system because it potentially inexpensive relatively easy scale. However, costs are still too high this technology resounding success. New manufacturing joinin...

Thermal conductivity of graphite bipolar plates (BPP) decreases with temperature. Thermal Contact resistance (TCR) between BPP and GDLs decreases with compression. GDL-BPP TCR increases with MPL and PTFE, regardless of the PTFE loading. High PTFE loading, MPL, and BPP outof-flatness increase the TCR dramatically. The graphite BPP-GDL TCR is a dominant resistance in a BPP-GDL assembly. a r t i c...

Abstract Bipolar plates are one of the most important components polymer membrane fuel cells. In this manuscript, rubber pad forming aluminum bipolar with Archimedes' screw-shaped channels and draft angle 90 $$^\circ$$ ∘ has been investigated. Hence, all possible combinatio...

The demand for polymer composite solutions in bipolar plates electrolyte membrane fuel cells (PEMFCs) has risen due to advantages over metal such as longer lifetime, weight reduction, corrosion resistance, flexible manufacturing, freedom of design, and cost-effectiveness. challenge with composites is achieving both sufficient electrical conductivity mechanical stability high filler content. A c...

Bipolar plates in proton exchange membrane fuel cells (PEMFCs) are confronted by the dilemma of low contact resistance and high corrosion resistance; this study aimed to simultaneously satisfy these dimensions a harsh environment. Using thick multilayer coatings can improve resistance, but would be largely compromised. To address challenge, we propose compatible tantalum/titanium-based on 316L ...

A novel bi-layer coating composed of a tantalum base layer with an Indium Tin Oxide (ITO) top was applied to titanium substrates. Samples were polarized ex situ in parameter study, where the pH, potential and temperature electrolyte altered, as well polarization duration. The Interfacial Contact Resistance (ICR) after showed increase time for first 24 h, then stabilized at approx. 30 mΩ cm2. Mi...

The flow-field design based on under-rib convection plays an important role in enhancing the performance of polymer electrolyte membrane fuel cells (PEMFCs) because it ensures the uniform distribution of the reacting gas and the facilitation of water. This research focused on developing suitable configurations of the anode and cathode bipolar plates to enhance the fuel cell performance based on...
