The pressure difference between the inlet and outlet of the reactant in fuel cells is called the
pressure drop, which is related to the water amount inside the fuel cells. In recent years …

Understanding the transport processes that occur in carbon-fiber papers (CFPs) used in fuel
cells, electrolyzers, and metal-air/redox flow batteries is necessary to help predict cell …

This work investigates the integration of polymer electrolyte membrane fuel cells (PEMFC)
into recently proposed hydrogen aircraft concepts. Based on a numerical optimization of the …

Excessive liquid water in the gas diffusion layer (GDL) of a polymer electrolyte fuel cell is
known to degrade the performance. Cross-flow through the GDL is applied to reduce the …

Multiphase flow in porous media is widely encountered in many scientific and engineering
