An electrical insulator is provided for insulation between the heat medium and the heat plate. Another heat medium passage may be further 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.

摘要： The present invention provides a fuel stack comprising: a plurality of fuel cell units stacked together in a direction of stacking each of which comprises an electrolyte element, a pair of electrodes holding the electrolyte element therebetween, and a pair of separators holding the electrodes therebetween; a pair of terminal plates each of which is disposed outside an end fuel cell unit located at an end of the stacked fuel cell units; and a terminal element extending outwardly in the direction of stacking from the outside surface of at least one of the terminal plates; wherein the location from which the terminal element extends is located within an area on the terminal plate, corresponding to an area in a passage for an oxidizing gas formed in the end fuel cell unit disposed adjacent to the terminal element where the partial pressure of water vapor is lower than the saturated water vapor pressure. More preferably, the terminal element is disposed as close to the centerline of the terminal plate as possible so that the total electrical resistance of the terminal element and the terminal plate is minimized. By this configuration, an increase in the total electrical resistance and water vapor condensation in the fuel cell units located at the ends of the stack may be prevented.

摘要： A fuel cell stack comprises a fuel gas supply passage and a fuel gas discharge passage for allowing a fuel gas to flow therethrough, penetrating through first and second separators. A fuel gas flow passage for supplying the fuel gas to each of fuel cell units is provided on a surface of the first separator. Curved surfaces, which are curved in a flow direction of the fuel gas, are provided corresponding to each of boundary portions between the fuel gas flow passage and the fuel gas supply passage and the fuel gas discharge passage. Accordingly, it is possible to effectively reduce the delivery pressure loss and the collection pressure loss of the fuel gas.

Wedge members are integrally inserted, over the plurality of fuel cell units, into communication holes of a fuel gas supply passage, an oxygen-containing gas supply passage, and a cooling water supply passage, as well as a fuel gas discharge passage, an oxygen-containing gas discharge passage, and a cooling water discharge passage. A fluid is uniformly delivered to each of the fuel cell units by the aid of the wedge members. Accordingly, the fluid of any one of a fuel gas, an oxygen-containing gas, and a cooling medium is uniformly delivered to each of the fuel cell units. Further, it is possible to simplify the arrangement of the fuel cell stack.
