Abstract
Disclosed are a membrane-electrode assembly for fuel cells with improved durability and a polymer electrolyte membrane fuel cell including the same. The membrane-electrode assembly includes an antioxidant, Sm-doped cerium oxide in the electrolyte membrane, which has a controlled microstructure through high-temperature heat treatment, thereby providing both superior antioxidant activity and excellent long-term stability.
