The electrolyte-strengthening substrate is formed so as to be larger than a joint area of the first conductive separator and a joint area of the second conductive separator in the joint portion. The electrolyte-strengthening substrate has an insulating property at least at an area where the electrolyte-strengthening substrate contacts with the brazing material.
