| 摘要 |
The invention provides an MEA-gasket assembly (1) comprising: an MEA (5) having a polymer electrolyte membrane (5A), catalyst layers and gas diffusing layers (5C); a plate-like frame (6) which is joined to a portion of the polymer electrolyte membrane (5A) so as to enclose the MEA (5), the portion being located in a peripheral region of the MEA (5) and which has a plurality of fluid manifold holes (12, 13, 14); and an annular gasket (7) formed on both faces of the frame (6), wherein an annular gap formed between the inner peripheral edge of the annular gasket (7) and the outer peripheral edges of the gas diffusing layers (5C) is at least partially closed.
