Abstract
To provide a membrane/electrode assembly for polymer electrolyte fuel cells, a polymer electrolyte fuel cell and processes for their production, which make it possible to stably exhibit a high power generation performance in various environments. A membrane/electrode assembly for polymer electrolyte fuel cells, which comprises a first electrode having a first catalyst layer and a first gas diffusion layer, a second electrode having a second catalyst layer and a second gas diffusion layer, and a polymer electrolyte membrane disposed between the first electrode and the second electrode, wherein the 90° peel strength at least one of the interface between the first electrode and the polymer electrolyte membrane and the interface between the second electrode and the polymer electrolyte membrane is at least 0.03 N/cm.
