“…In general, this water is evacuated by evaporation toward the atmosphere in the case of air-breathing fuel cells [3], or is carried by the cathodic air/O2 overflow [4]. Many studies focus on what happens in the cathode, through various twophase models [4][5][6][7], sometimes modelling the porous medium's geometry [1], taking into account the permeability, the porosity, and the wettability of the electrode [5,[8][9], and dealing with the interfacial issues that multi layers electrodes can raise [1,[10][11]. It involves complex mass transport, and energy balances, that can be carried out at different scales, from a macroscopic [9,12] to a microscopic point of view [9,[13][14].…”

“…They sometimes deal with global balances, taking into account the hydric interactions between the gas channels, the membrane and the two electrodes, and modelling water transport and transformation in each of these media, like Springer et al in [31], or like in [8,37]. Nevertheless, authors often focus on modelling the electrodes hydric behaviour, and especially the cathode [5][6][7]9,22]. Indeed, this is first of all where water is produced; this is the source location for mostly every hydric issue.…”

To cite this version:M. Zeidan, Ch. Turpin, F. Cantin, S. Astier. Steady state macroscopic model of the influence of water on the performances of a micro air-breathing fuel cell. European Physical Journal: Applied Physics, EDP Sciences, 2011, 54 (2) Model of the influence of water on a micro air-breathing fuel cell Abstract. Water management is one of the most crucial issues to drive PEM fuel cells. The challenge is enhanced in the case of Micro Air-Breathing Proton Exchange Membrane Fuel Cells (µABFC): their thinness and their reduced surface indeed make their hydration state fast changing and very sensitive to the experimental conditions (temperature and Relative Humidity (RH)). It can lead to strong flooding or drying out issues. Firstly, this study highlights this sensitivity by various measurements. Then a steady state macroscopic model for the µABFC is proposed, focusing on the cathode, using a rather original approach for diffusion in porous media. Finally, a literal steady state formula for the water content is provided, and its influences on the performances of the µABFC are explicitly proposed. The model is parameterized and compared to measures in several atmospheric conditions.

“…Perhaps the easiest way to do the superposition is to combine linearly the two driving forces for water, as many models have done [38,55,66,67,106,[111][112][113][114][115][116] …”

“…Only few models exist for liquid water. A model by You and Liu [8] focused on the mass transport limitations and water management in a two dimensional cathode under isothermal conditions. Most of the models are validated on a global scale with polarization curves, which are unable to capture the current density distributions on a local level.…”

Ion transport rate of PAFC, AFC, PEMFC, DMFC and SOFC fuel cells under the influence of an electric field and concentration gradient were evaluated for static electrolytes. AFC are the best fuel cells for higher current applications while direct methanol fuel cells DMFC are the best for lower current applications at lower temperatures. An equation for voltage output of a general fuel cell was obtained in terms of temperature and partial pressure of reactants. Performance of a 2D fuel cell was analyzed by simulating polarization and power curves for a fuel cell operating at 60 ºC with a limiting current density of 1.5 Acm -2 . The maximum power for this fuel cell was 8.454 W delivering 82 % of maximum loading current density. When the temperature was increased by one third of its original value, the maximum power increased by 6.75 % and at 60 ºC for a 10 times increment of partial pressure of reactants, the maximum power increased by 2.43 %.The simulated power curves of the fuel cells were best described by cubic fits.
