Abstract
A gas diffusion layer (6) is sandwiched between catalyst electrode layers (5) and separators (1, 2), and side faces (6A, 6B) of the gas diffusion layer (6) are arranged so as to face a gas inlet manifold (7) and outlet manifold (8), and partition the inlet manifold (7) and outlet manifold (8). In the gas diffusion layer (6), gas flows from the side face (6A) facing the inlet manifold (7), flows through the interior, and flows out from the side face (6B) facing the outlet manifold (8).
Claims7
A fuel cell, comprising:
- a solid polymer electrolyte membrane;
- a catalyst electrode layer disposed on the solid polymer electrolyte membrane;
- a gas diffusion layer disposed on the catalyst electrode layer;
- and
- a separator disposed on the gas diffusion layer and forming an inlet manifold and outlet manifold between the electrolyte membrane, wherein:
- one surface of the gas diffusion layer faces the inlet manifold, and the other surface of the gas diffusion layer faces the outlet manifold, the inlet manifold and outlet manifold being partitioned by the gas diffusion layer;
- and
- gas flows from the one surface facing the inlet manifold and into the gas diffusion layer, flows through the interior of the gas diffusion layer, and flows out from the other surface facing the outlet manifold.
