Temperature control device for a fuel cell
A temperature control device for a fuel cell has a heat exchanger piping sandwiched between a pair of temperature control plates in heat exchange relation therewith, said temperature control plates having reaction gas conduit means on surfaces opposite to confronting surfaces thereof. A circulation piping is adapted for circulation by a heat medium and is hermetically connected to an outside piping located outside of said temperature control plates for providing a closed piping system therewith. Said circulation piping contains sealed-in heat medium so that a portion of the inside space of the circulation piping is left for a gaseous phase of the heat medium. Heat exchanger means are provided to said outside piping to effect heat exchange with heat medium in said circulation piping.
