A separator for a fuel cell includes a flow field plate and a main body plate. The flow field plate has a porous plate structure and is bonded to an outer surface of a gas diffusion layer to form a reaction gas flow field. The main body plate is bonded to an outer surface of the flow field plate to seal the reaction gas flow field. The flow field plate has protrusions that protrude from both surfaces of the flow field plate in a repetitive pattern, forming an uneven structure. The flow filed plate has a land portion bonded to the gas diffusion layer at a sharp tip of a protrusion thereof protruding from one surface of the flow field plate and a bonding portion bonded to the main body plate at an opposite sharp tip of a protrusion thereof protruding from the other surface of the flow field plate. |
