摘要

PURPOSE: A manufacturing method of polymer electrolyte membrane for solid polymer type fuel cell including hydrophilicity intensifier, a polymer electrolyte membrane for the solid polymer type fuel cell manufactured thereby, a membrane electrode assembly including the same, and a solid polymer type fuel cell are provided to reduce contact resistance between electrode and electrolyte membrane and to enhance conductivity. CONSTITUTION: A manufacturing method of polymer electrolyte membrane for solid polymer type fuel cell including hydrophilicity intensifier comprises the following steps: preparing transition metal doped hydrophilicity intensifier; preparing a polyelectrolyte solution for the solid polymer type fuel cell; uniformly mixing the transition metal doped hydrophilicity intensifier with the membranous polymers electrolyte solution; and forming a polymer electrolyte membrane in the transition metal doped hydrophilicity intensifier is uniformly dispersed.
