文摘

EIS is employed to investigate the MEA design of a PEM fuel cell. Effects of MPL, membrane thickness and GDL hydrophobic treatment are studied. MPL increases cell output at low to medium currents but reduces it at high currents. Better results are obtained when employing a thinner Nafion membrane. GDL hydrophobic treatment improves the cell performance.
