High performance of electrode with low Pt loading prepared by simplified direct screen printing process in PEM fuel cells

A simplified screen printing method for the better performance of the electrodes, with or without gasket unified, in the polymer electrolyte membrane fuel cells (PEMFC) was proposed. It was observed that the gasket unified showed better performances at high current area due to the blocking effect on the gas leakage during the operation. It was also observed that the cell performance varied above current density area when compared a cell made with gasket unified direct screen printing method. It was found that the output voltage of 0.5 and 0.38 V could be obtained at 0.038 and 0.075 g/cm2 of Pt loadings.
