Abstract: There is provided a technique of reducing the possibility of the occurrence of wrinkles in the process of bonding strip-shaped members to each other. A long strip-shaped first member is conveyed in a longitudinal direction of the first member. A width of a long strip-shaped second member in the shorter direction of the second member is larger than a width of the first member in a shorter direction of the first member. The second member is placed such that respective ends in a shorter direction of the second member are freed. The second member is bonded to the first member being conveyed, such that the shorter direction of the first member is aligned with the shorter direction of the second member and that respective ends in the shorter direction of the first member are placed between the respective ends in the shorter direction of the second member. The second member bonded to the first member is then conveyed along with the conveyed first member.

Abstract: A storage case (300) includes a case body (320) formed by joining a plurality of members (301, 302) with a joint structure (303a, 303b, 304) an opening (16) formed in the case body (320), a closure member (14) capable of closing the opening (16), a seal structure (17) provided between the case body (320) and the closure member (14), and a foreign-matter guide portion (10) provided on an outer surface of the case body (320), aside from the joint structure (303a, 303b, 304), such that the foreign-matter guide portion is located above the seal structure in the vertical direction of the storage case.

Abstract: A cooling device for a fuel cell is provided which can maintain the electric conductivity of a liquid coolant within the predetermined range even if a load suddenly changes. In the cooling device for a fuel cell (10), the parameters (TH, TL) relating to the coolant temperature can be controlled so that the electric conductivity (S) at a target set temperature is maintained within a target electric conductivity range (Smax-Smin) based on the correlation between the parameters relating to the coolant temperature and the electric conductivity of the coolant. Because the electric conductivity is feed-forward controlled based on the correlation between the parameters relating to the coolant temperature and the electric conductivity of the coolant, the electric conductivity of the coolant can be reliably maintained within the target range even when electric conductivity with a comparatively poor responsiveness is controlled.
