A fuel cell 100 includes a joint portion A in which a first conductive separator 1, an electrolyte-strengthening substrate 3 and a second conductive separator 8 are jointed in order with a brazing materials 11 and 12. The electrolyte-strengthening substrate 3 is formed so as to be larger than a joint area of the first conductive separator 1 and a joint area of the second conductive separator 8 in the joint portion. The electrolyte-strengthening substrate 3 has an insulating property at least at an area where the electrolyte-strengthening substrate 3 contacts with the brazing materials 11 and 12. |
