Abstract
The present invention relates to a porous organic polymer-based hydrogen ion conductive material and a method for preparing the same. More specifically, the present invention relates to a method for preparing a porous organic polymer (POP)-based material with high proton conductivity that is applicable to a membrane electrode assembly (MEA) of a proton exchange membrane fuel cell (PEMFC). The porous organic polymer-based proton conductive material of the present invention can be prepared in an easy and simple manner by microwave treatment and acid treatment requiring short processing time and low processing cost. In addition, the porous organic polymer-based proton conductive material of the present invention can be developed into a highly proton conductive material having the potential to replace Nafion through a simple post-synthesis modification. Therefore, the porous organic polymer-based proton conductive material of the present invention is suitable for use in a proton exchange membrane fuel cell.
