Separator for fuel cell and fuel cell including the same

A separator for a fuel cell, comprising:

• a separator body;
• and
• a porous structure which is stacked on one surface of the separator body and has a plurality of pores defined therein to provide a path through which a fluid flows,
• wherein the separator body comprises:
• a fluid inlet part having a space into which the fluid is introduced;
• a reaction region configured to receive the fluid;
• and
• a diffusion part which is provided between the fluid inlet part and the reaction region and has a passage to provide a path through which the fluid within the fluid inlet part is supplied to the reaction region,
• wherein the porous structure is stacked on one surface of the reaction region, and
• a first inlet region, which is provided at the same height as the fluid inlet part in a height direction in an inlet region of the porous structure facing the diffusion part, is provided closer to a central region of the porous structure than a second inlet region except for the first inlet region in the inlet region of the porous structure facing the diffusion part.
