Commercial membranes for proton exchange membrane fuel cell(PEMFC) is widely used because of theirs many advanced properties. But, there are still many problems to be solved due to its low operation temperature, around 80℃, of fuel cell. To solve these problems, PEMFC that can be worked at temperature above 150℃ have been studied. In this study, PBI type membrane was synthesized by introducing inorganic material. To make the membrane electrode assembly(MEA), membrane and electrode which is gas diffusion layer(GDL) sprayed with Pt supported on carbon as catalyst were attached and pressed at high temperature and pressure. The properties of the membrane were characterized by impedance analyzer and cell station. |
