Patent ID: 11205784

Abstract:
A fuel cell according to the present disclosure includes separators 11 and 12 made of metal and having projection-depression shapes, and gas diffusion layers 13 and 14. Conductive particles 21 are buried in a projecting part on one surface of each of the separators 11 and 12, and carbon fibers 22 are buried in a projecting part on the other surface of each of the separators 11 and 12. The projecting parts on the one surfaces of the separators 11 and 12 abut against each other so that the conductive particles 21 buried in these projecting parts come into contact with each other. Further, the projecting parts on the other surfaces of the separators 11 and 12 abut against the gas diffusion layers 13 and 14, respectively, so that the carbon fibers 22 buried in these projecting parts come into contact with the gas diffusion layers 13 and 14, respectively.
