  "textContent": "A fuel cell membrane electrode assembly and a polymer electrolyte fuel cell, which improve drainage in a high current range where a large amount of water is produced, without hindering water retention under low humidification conditions, and exhibit high power generation performance and durability even under high humidification conditions. A fuel cell membrane electrode assembly according to a first embodiment of the present invention includes a polyelectrolyte film, and two electrocatalyst layers sandwiching the polyelectrolyte film. At least one of the two electrocatalyst layers includes catalyst support particles with a hydrophobic coating, a polyelectrolyte, and a fibrous material having an average fiber diameter that is 10 nm or more and 300 nm or less. The fibrous material has a mass that is 0.2 times or more and 1.0 times or less the mass of the carrier in the catalyst support particles.",
