제목 Polymer Electrolyte Membrane with High Performance for Fuel Cell and Hydrogen Purification Applications
초록 In this work, polybenzimidazole (PBI) based organic-inorganic composites as the proton exchange membranes (PEM) are fabricated and their properties are measured for applications in both high temperature proton exchange membrane fuel cells (PEMFC) and hydrogen purification device known as electrochemical hydrogen pumps (EHP). Basically, in order to secure improved performances such as proton conductivity and mechanical properties, it is very important to increase phosphoric acid (PA) doping level of the membrane with appropriate mechanical strength via some strategies. Among them, introduction of inorganic materials into the PBI matrix is effective method to enhance the properties when the filler is well dispersed in the polymer. In addition, for increasing the performance of PA doped membranes, a “one step” method is used. The enhanced properties of composites imply that the composite membranes can become possible alternatives for HT-PEMFC and EHP applications.
