Abstract: In order to produce a battery carrier which has a battery tray with a cooling plate, a tray plate and a cooling plate are joined to one another, wherein the cooling plate has at least one preshaped cooling duct. The tray plate jointly with the cooling plate is then formed by folding to produce the battery tray. During the folding of the tray plate and the cooling plate, a cooling duct section is bent around a bottom edge of the battery tray. The cooling duct is provided with connection elements via which a cooling fluid is supplied and discharged. During the course of the finishing, end shape-producing shaping of the cooling duct can also be performed. Internal pressure is applied to the cooling duct in order to restore the shape of the cooling duct which collapsed due to the forming.

Abstract: A fuel cell includes a membrane electrode assembly, gas diffusion layers stacked on each side of the membrane electrode assembly, respectively, separators stacked on the gas diffusion layers, respectively, the separators including channels through which reactant gases move and lands in contact with a respective one of the gas diffusion layers, and a flow path forming part provided on a land surface of one of the lands in contact with the respective one of the gas diffusion layers, the flow path forming part providing a condensate flow path for moving condensate between the land surface and the one of the gas diffusion layers.

Abstract: A power continuity unit includes a battery pack, a power converter, and a housing assembly. The battery pack includes a plurality of battery cells with monitoring devices that monitor the voltage of the associated battery cell and trim excess voltage. During daytime, the power converter converts a portion of the direct current (DC) power it receives from an alternative energy device into alternating current (AC) power and directs it to a user, while the remainder is stored in the battery pack. During nighttime, the power converter converts DC power it receives from the battery pack into alternating current (AC) power and directs it to the user. The housing assembly provides structural support and protection to the battery pack; its configuration depends on the type of battery cell being used.

Abstract: Fuel cell electrocatalysts and support structures thereof are described herein. The support structures include a suboxide core comprising an oxygen deficient metal oxide and a dopant, and an outer shell covering the suboxide core. The outer shell comprises the dopant in oxide form. The dopant of the suboxide core provides for the suboxide core to be conductive. Methods of forming fuel cell electrocatalysts and support structures thereof are also described herein.

Abstract: The present invention relates to an active material analysis apparatus for analyzing an active material of a battery. An active material analysis apparatus of the present invention may comprise: a lower plate at which an electrode is located; an upper plate which is coupled to the lower plate with the electrode disposed therebetween; a sealing member positioned at a joint part between the upper plate and the lower plate; and a coupling member for coupling the upper plate and the lower plate, wherein: the upper plate includes an opening provided to allow a light source to be radiated to the electrode; an electrolyte is filled in a space between the upper plate and the lower plate; the opening is covered by glass; and the upper plate faces a liquid surface formed by the electrolyte and is positioned at a position higher than that of the liquid surface.

Abstract: A method of making a solid oxide fuel cell (SOFC) includes the steps of providing a first SOFC layer laminate tape comprising a first SOFC layer composition attached to a flexible carrier film layer, providing a second SOFC laminate tape comprising a second SOFC layer composition attached to a flexible carrier film layer, and providing a third SOFC layer laminate tape comprising a third SOFC layer composition attached to a flexible carrier film layer. The first SOFC layer laminate tape, the second SOFC layer laminate tape, and the third SOFC layer laminate tape are assembled on rolls positioned along a roll-to-roll assembly line. The laminate tapes are sequentially laminated and calendered and the flexible carrier films removed to provide a composite SOFC precursor laminate that can be sintered and combined with a cathode to provide a completed SOFC. An assembly for making composite SOFC precursor laminates is also disclosed.
