摘要：
A fuel cell is formed by stacking a plurality of unit cells. Each of the unit cells includes a membrane electrode assembly, and an anode side metal separator and a cathode side metal separator sandwiching the membrane electrode assembly therebetween. In a surface of the cathode side metal separator, metal portions are exposed in at least part of a second flat portion in an area surrounded by seal lines SL of the anode side metal separator. Cutouts are formed on a surface of the cathode side metal separator by cutting at least part of the second flat portion up to the metal portions thereby to expose the metal portions through the cutouts.
