Numerical modeling and investigation of foreign cation contamination on the performance of proton exchange membrane fuel cells
Proton exchange membrane fuel cells (PEMFCs) can be used as power sources in a wide variety of application scenarios due to the attractive advantages. Foreign cations introduced by air can cause a decrease in the output performance and durability of PEMFCs. In this study, a one-dimensional mathematical model is established to investigate the effect of foreign cation (Na+) contamination on the performance of PEMFCs. The performance degradation is observed due to the presence of Na+ and it becomes more severe with decreasing cell voltage. The maximum power density of the fuel cell without Na+ contamination (case 0) is 0.435 W/cm2, while the maximum power densities of the fuel cells with Na+ contamination (case 1, case 2, case 3, and case 4) are 0.385 W/cm2, 0.332 W/cm2, 0.275 W/cm2, and 0.206 W/cm2, respectively. In addition, the local transport processes are strongly affected in PEMFCs due to the cation contamination.
期刊介绍：
Ionics is publishing original results in the fields of science and technology of ionic motion. This includes theoretical, experimental and practical work on electrolytes, electrode, ionic/electronic interfaces, ionic transport aspects of corrosion, galvanic cells, e.g. for thermodynamic and kinetic studies, batteries, fuel cells, sensors and electrochromics. Fast solid ionic conductors are presently providing new opportunities in view of several advantages, in addition to conventional liquid electrolytes.
