Abstract

A polymer electrolyte membrane includes a fluorinated polymer membrane and a coating layer including a hydrocarbon-based ionomer on at least one surface of the fluorinated polymer membrane. The polymer electrolyte membrane maintains high hydrogen ion conductivity and has improved performance under high temperature and low humidity conditions. A membrane electrode assembly and a fuel cell including the polymer electrolyte membrane are also disclosed.
