A temperature adjustment device (and) includes: an insulation layer () provided in contact with bottom parts of the plurality of batteries (Bt); and a flow passage forming member () that is located on a side opposite to the plurality of batteries with the insulation layer interposed therebetween, and forms a flow passage () of cooling medium. The flow passage includes a plurality of cooling flow passages (fto f) that face the bottom surfaces of one or more different batteries of the plurality of batteries with the insulation layer interposed therebetween, a common inflow passage () that is connected to the plurality of cooling flow passages and in which the cooling medium is flowed, and a common exhaust passage () which collects and exhausts the cooling medium exhausted from the plurality of cooling flow passages. A cross-sectional area of a cooling flow passage corresponding to a first battery of the plurality of batteries among cross-sectional areas of the plurality of cooling flow passages is larger than a cross-sectional area of a cooling flow passage meeting a second battery whose temperature is lower than the temperature of the first battery in a use state. The cross-sectional areas of the plurality of cooling flow passages have cross sections parallel to a face of the insulation layer in contact with the bottom surfaces.

Temperature adjustment device

An ion exchanger used in a cooling system of a fuel cell system, includes: a communicating tube portion including a first flow path which allows coolant introduced from one side to pass therethrough to the other side; a case portion which is provided to communicate with the communicating tube portion; and a storage body which is assembled to the case portion, has a second flow path in which a part of the coolant branches and flows from the communicating tube portion, and is merged with the communicating tube portion again, and stores an ion exchange resin in the second flow path, wherein: an assembled state of the storage body with respect to the case portion is changeable into a plurality of kinds; and a proportion of the coolant that flows to the second flow path is changeable by changing the assembled state of the storage body.

Ion exchanger

An ion exchanger for a cooling system of a fuel cell system includes: a communicating pipe part with the two ends thereof configured respectively to be connectable to predetermined piping arranged in the cooling system, and including a substantially linear shaped first flow path; and a storage case including a second flow path configured such that, when a part of the coolant introduced into the communicating pipe part branches from the coolant of the communicating pipe part and flows toward the second flow path, such partial coolant, after introduced into the second flow path, is allowed to flow therethrough and join again the remaining coolant of the communicating pipe part, while ion exchange resin is stored in the second flow path, wherein an introduction device for introducing the coolant into the second flow path is arranged in the inside of the communicating pipe part.
