A numerical investigation of the effects of membrane swelling in polymer electrolyte fuel cells

Nernst–Planck modeling of multicomponent ion transport in a Nafion membrane at high current density

“…Substitution of (47) in (43) and (44) results in (48) and (49), respectively. For a system of only sodium and hydroxide, (47) reduces to (50).…”

“…It shows that for a certain total number of pores, there is a unique set of channel diameter and active number of pores that fit to the experimental values of the membrane voltage drop and sodium transport number. Dry membrane density (kg m EW (-) 1100 [36] Membrane porosity (m void 3 /m m 3 ) 0.27 [48,49] Sodium hydroxide concentration in both anolyte and catholyte (wt%) 15…”

A review of recent development: Transport and performance modeling of PEM fuel cells

“…The increase in relative humidity at dry side inlet does not provide any benefit. Tiss et al [22] presented a two-dimensional, non-isothermal model considering the membrane water content, thermal and mass diffusion in the cathode of a PEM fuel cell. They discovered that membrane water content can be affected by the parameters in the cathode such as humidification temperature, inlet velocity, and membrane characteristics.…”

Fuel cell/back-up battery hybrid energy conversion systems: Dynamic modeling and harmonic considerations

“…Analysis of the effects of different chemical materials and fabrication techniques on the performance of different fuel cell types has been the subjects of many researches the main goal of which is to improve fuel cells performance [14]. For example, effects of membrane swelling on the performances of polymer electrolyte fuel cells were determined in [15]. Modifying the physical properties of fuel cells to meet new demands and to adapt them to new applications such as buildings has been addressed in some recent researches [16].…”
