Abstract: Provided is a resin film for laminating a metal plate comprising a resin composition including a polyester-based thermoplastic elastomer and a thermoplastic polyester having a glass transition temperature (Tg) of 70° C. or more and 90° C. or less where the thermoplastic elastomer is dispersed in the thermoplastic polyester, wherein a content of the thermoplastic elastomer in the film is 2 to 50 wt %, and an absolute value ?Tg of a difference between a glass transition temperature of the thermoplastic polyester and a glass transition temperature of the film satisfies the following Expression (1): ?Tg<0.5×W??(1) wherein W represents the thermoplastic elastomer content (wt %) in the film.

Abstract: Liquid fuel received in a container can be injected manually in a safe, easy and convenient manner. In a fuel cell cartridge for fuel cells in which at a port portion (14) of the container (10) in which the liquid fuel is received, there is provided a plug (30P) that is adapted to be connected with a fuel cell for filling the fuel thereinto, a bellows portion (15) acting as a portion capable of extension and contraction is formed in at least a part of the container (10), and on the plug (30P), there is provided a valve mechanism (34) which is held in a normally closed state in a free state thereof, and is opened when the plug is connected with the fuel cell (70).

Abstract: A fuel bottle 10 for a fuel cell having a bottle main body 12 for containing fuel for a fuel cell and comprising a nozzle portion 11 at the tip portion of the bottle main body 12 on which a coupler for connecting with a main body of a fuel cell can be attached and a trunk portion having a generally elliptic shape in cross section and having been formed by blow molding. In this bottle 10, length L1 in one direction of minor axis from the center On of the nozzle portion of the elliptic shape in cross section differs from length L2 in the other direction of the minor axis from the center On of the nozzle portion. By this structure, a moving space of a push button when the fuel bottle 10 is housed in a hard case can be secured while necessary capacity of the fuel bottle 10 is secured.
