Method of Preparing Hierarchically Porous Polymers and Hierarchically Porous Polymers Prepared Thereby

摘要

The present invention relates to a method for manufacturing a membrane electrode assembly for a polymer electrolyte fuel cell having a hierarchical corrugated structure, wherein a hierarchically corrugated structure prepared on a polystyrene film is transferred to PDMS, and then transferred to a polymer phase through thermocompression bonding of PDMS, followed by a catalyst layer The membrane electrode assembly for a polymer electrolyte fuel cell with a hierarchically corrugated structure prepared by applying Even so, there is an effect of remarkably improving the performance of the fuel cell.
