The present invention proposes a structure of a battery module in which a spacer can slide by means of a guide member constituting the battery module and can be positioned. A battery module according to the present invention is a battery moduleprovided with a battery blockin which a plurality of rectangular battery cellsare arranged and laminated, and includes a spacerwhich intervenes between the plurality of battery cells, guide membersandwhich slidably support the spaceralong a laminating direction of the battery cells, and end platesas a pair which are respectively arranged on one side and the other side of the guide membersandin a sliding direction and which sandwich the battery blockfrom both sides in the sliding direction.

Battery module

An electrical storage apparatusincludes a plurality of battery modulesand cooling passages A, B for cooling each of the battery modules. The cooling passage A is configured so as to cool all battery modulesmounted in the electrical storage apparatusat all times during charging. The cooling passage B is configured so as to cool only a new battery moduleas a replacement during charging. This enables the battery modulehaving a temperature during charging higher than that of a battery moduleyet to be replaced to be subject to forced cooling, thereby preventing performance of the battery modulefrom being degraded.

An apparatus for mixing gaseous fuel and air for combustion, particularly premixing-type combustion in a gas turbine, has a conduit providing a passage for flow of the air with a reverse bend defined by opposed first and second wall portions that bound respectively the outside and the inside of said reverse bend as seen in a longitudinal section. The reverse bend establishes a flow region of air having a velocity gradient extending transversely across the conduit from a high velocity zone adjacent the first side wall portion at the outside of the reverse bend to a low velocity zone. Injection means for the gaseous fuel injects the fuel from the first side wall portion into the high velocity zone with a velocity component transverse to the air flow and in a direction towards the low velocity zone. Rapid and uniform mixing is obtained.
