Excess of liquid water in gas channels of polymer electrolyte fuel cells is responsible for
malfunctioning of these devices. Not only it decreases their efficiency via partial blockage of …

Thin porous media are present in multiple electrochemical energy devices, where they
provide key transport and structural functions. The prototypical example is gas diffusion …

Abstract A transient, two-phase, 2D model of a proton-exchange-membrane fuel cell
(PEMFC) is developed and used to study liquid-water dynamics. Porous structure of the cell …

Energy security, climate change and air pollution are all motivations for further development
of fuel cells. Still, technical problems relating to water management, continue to hinder the …

The temporal stability and spatial homogeneity of current density are key factors in Polymer
