The European Physical Journal Applied Physics, 2011 This paper presents a new steady state model which contains fewer polarisation curve fitting parameters compared to other semi-empirical models. The established model is also defined at no load operation and can be fitted perfectly to the static polarisation curve for a wide range of cell currents.

Two-phase flow equations in porous media for PEMFC (Proton Exchange Membrane Fuel Cells)
Science and Technology for Energy TransitionIn Proton Exchange Membrane Fuel Cells (PEMFC) for electrical mobility, the water management and transport are very important. Water vapour is produced, and liquid water can be formed since the gases can become saturated by water vapour production during
