Abstract
A heat medium passage for controlling the temperature of the electric power generation section is separated from the electric power generation section of a fuel cell including a plurality of separators and electric power generating elements alternately laminated in a lamination direction. A heat plate exchanges heat with at least one of the heat medium passage and a heat medium in the heat medium passage and is connected to the separators to provide electrical conduction between the separators in the lamination direction. An electrical insulator is provided for insulation between the heat medium and the heat plate. Another heat medium passage may be provided on the other side. A temperature control system for the fuel cell may include a burner for supplying the heated heat medium to the heat medium passage and may comprise first and second fluidic passages independently to selectively use the first and second fluidic passage.
