Claim 0:
1. A fuel cell comprising:
a membrane electrode assembly;
gas diffusion layers stacked on each side of the membrane electrode assembly, respectively; and
separators stacked on the gas diffusion layers, respectively, the separators comprising:
channels through which reactant gases are movable;
lands in contact with a respective one of the gas diffusion layers; and
a flow path forming part protruding from a land surface of one of the lands in contact with the respective one of the gas diffusion layers, the flow path forming part providing a condensate flow path configured to move condensate exiting between the land surface and the one of the gas diffusion layers,
wherein the flow path forming part comprises protrusion patterns protruding from the land surface and spaced apart from one another,
wherein the protrusion patterns cooperatively form the condensate flow path,
wherein the flow path forming part comprises:
a first protrusion pattern,
a second protrusion pattern spaced apart from the first protrusion pattern in a width direction of the land,
a third protrusion pattern spaced apart from the first protrusion pattern in a longitudinal direction of the land, and
a fourth protrusion pattern spaced apart from the second protrusion pattern in the longitudinal direction of the land
wherein each of the protrusion patterns comprises:
a first protrusion,
a second protrusion spaced apart from the first protrusion in the width direction of the land,
a third protrusion spaced apart from the first protrusion in the longitudinal direction of the land, and
a fourth protrusion spaced apart from the second protrusion in the longitudinal direction of the land, and

wherein the first protrusion, the second protrusion, the third protrusion and the fourth protrusion cooperatively form an X shape.
