Abstract: A lithium secondary cell includes a cell case that includes a covering region and an outer peripheral region. The covering region is a rectangular region overlaid on the positive electrode, the separator, and the negative electrode in a direction of superposition. The outer peripheral region is a rectangular frame-like region surrounding the covering region. The outer peripheral region includes first regions that are band-like regions extending respectively along a pair of long sides. In the first regions, a first sheet portion and a second sheet portion are bonded together. A second region is a band-like region extending along the covering region between the covering region and at least one first region out of the pair of first regions. In the second region, the first sheet portion and the second sheet portion are in contact with or in close proximity to each other without being bonded together.

Abstract: A positive electrode of a lithium secondary battery includes a sheet-like positive electrode current collector having conductivity, and a positive electrode active material plate that is a plate-like ceramic sintered compact joined to the positive electrode current collector via a conductive joint layer. The positive electrode active material plate includes at least one active material plate element. This at least one active material plate element is joined to the positive electrode current collector. A main surface of the active material plate element that opposes the positive electrode current collector includes a joint region in which the conductive joint layer exists between the positive electrode current collector and the active material plate element and a non-joint region in which the conductive joint layer does not exist between the positive electrode current collector and the active material plate element. The non joint region is arranged around the joint region.

Abstract: A moving body, such as a vehicle, having one or more fuel cells mounted thereon. The fuel cells, which power the moving body, generate electricity and release water as a by-product. Accordingly, the moving body includes a water discharge module that releases water produced by the fuel cells to the atmosphere using a water outlet. The water outlet may be located in a front section of the moving body. The moving body may further include a water tank that temporarily stores water before releasing the water to the atmosphere.

Abstract: Water contained in exhaust gas discharged from a fuel cell stack is separated by a gas-liquid separator and is accumulated in a recovery tank. The procedure of the invention sets a release amount of water and selects one or multiple positions for water release, based on the driving conditions including the vehicle speed and the acceleration, the turning state, activation or non-activation of skid reduction control, the distance from any object detected by clearance sonars, a distance from a subsequent vehicle measured by an extremely high frequency radar, and the presence of raindrops detected by a raindrop detection sensor, and releases the water accumulated in the recovery tank from water outlets at the selected one or multiple positions among water outlets at multiple different locations. This arrangement ensures adequate release of the water produced by the fuel cell stack to the atmosphere.

Abstract: Variation of the amount of power to be produced by a fuel cell unit is limited in accordance with a relationship between an output voltage of the full cell unit and an oxidization-reduction potential of catalyst of a fuel cell of the fuel cell unit. The amount of power to be used to charge or discharged from a battery is then corrected according to the limited variation of the amount of power to be produced by the fuel cell unit 40, so as to meet the required system power output.
