A fuel cell FC includes: a membrane electrode assembly 2 including a frame 1 at a peripheral portion; and a separator 3 disposed on both sides of the frame 1 and the membrane electrode assembly 2, wherein a protrusion 3R and a counterpart groove 1G where a tip of the protrusion 3R is inserted are respectively formed on portions of the frame 1 and the separator 3 facing each other, and the tip of the protrusion 3R is immersed in an adhesive 10 that is injected in the groove 1G so that the groove 1G and the protrusion 3R are joined to each other. With this configuration, the sealing between the frame 1 and the separator 3 is greatly improved. |
