Title:
膜電極接合体及び固体高分子形燃料電池
Document Type and Number:
Japanese Patent JP7476888
Kind Code:
B2
Abstract:
A membrane electrode assembly and a polymer electrolyte fuel cell are provided, which are capable of improving water release in a high current region, where a large amount of water is generated, without impairing water retention under low humidity conditions, and also capable of exhibiting high power generation performance and durability under high humidity conditions, and also reducing the production cost of the electrode catalyst layer. A membrane electrode assembly (11) of the present embodiment includes a polymer electrolyte membrane (1), and a pair of electrode catalyst layers (2, 3) sandwiching the polymer electrolyte membrane (1). At least one of the pair of electrode catalyst layers (2, 3) contains catalyst-supporting particles having a hydrophobic coating, hydrophobic polymer fibers, and a polymer electrolyte.
