A fuel cell disclosed in the present specification includes a membrane electrode assembly, a separator adjacent to the membrane electrode assembly, and a gas channel through which fuel gas, oxygen gas, or air passes. The gas channel is provided on a face of the separator, the face facing the membrane electrode assembly. The gas channel has a wave shape extending in a lateral direction while meandering in an up-down direction. The gas channel includes an upward convex curved portion and a downward convex curved portion that are alternately connected. The downward convex curved portion is shorter than the upward convex curved portion. By making the downward convex curved portion shorter than the upward convex curved portion, water remaining in the downward convex curved portion is easily blown downstream by the force of the gas. That is, the amount of water remaining in the gas channel can be reduced.
