Abstract:
In a method for producing an individual cell for a battery with an electrode stack arranged inside a cell housing formed by two electrically conductive housing side walls and an interposed, peripheral, electrically insulating frame, current drain tabs of each polarity are connected respectively to a corresponding pole contact of the electrode stack and an electrically conductive connection is produced between the pole contacts and the housing side walls. According to the invention, the electrically conductive connection is generated in an open state of the individual cell.
Abstract:
A method and apparatus for cooling a fuel cell system. The system includes a fuel cell (1) having a cooling device (15) which forms part of a cooling circuit including a liquid coolant. The cooling circuit, outside the fuel cell (1), contains a device by which any gases which may penetrate into the liquid coolant from the fuel cell (1) are separated out and fed to the mass flow of the oxygen-containing gas which is fed into the fuel cell.
Abstract:
A device for producing an abrupt or sudden feed motion contains in a casing a feed device, which can be triggered by a trigger. The force necessary for advancing the feed device is applied by a spring, which is tensioned with the aid of a drive. The tool requires no cartridges for propellant charges.
Abstract:
A battery includes a stack of bipolar individual battery cells, each of which includes an electrode stack and two sheet metal covers bounding the individual battery cell at least in the stacking direction. The electrode stack is connected to at least one of the sheet metal covers by at least one weld. In the region of the at least one weld, the sheet metal cover welded to the electrode stack and/or the sheet metal cover of the adjacent individual battery cell in contact with the sheet metal cover is/are of a set-back design. As a result, the sheet metal covers of adjacent individual battery cells do not have any contact in the region of the at least one weld.
Abstract:
A single cell for a battery includes two housing parts, a cell frame, an electrode foil stack situated between the housing parts, and an insulating element situated between the housing parts. The insulating element electrically separates the two housing parts from one another. The insulating element has dimensions such that in the assembled state of the single cell the insulating element projects, at least in part, beyond a first housing part at the edge, forming a projection. The first housing part is enclosed, at least in part, by the insulating element at an edge.
Abstract:
An individual cell for a battery comprises an electrode stack disposed within a cell housing and a method for the production thereof. The individual electrodes, preferably electrode foils, are electrically connected to lead vanes, and at least electrodes of different polarity are separated and insulated from each other by a separator preferably a separator foil. Lead vanes of the same polarity are electrically connected to each other to form a pole. The lead vanes of a pole are electrically compressed with each other and/or welded to each other.
Abstract:
The invention relates to a battery with a heat conducting plate for controlling the temperature of the battery. The battery comprises a plurality of single cells connected in parallel and/or in series to each other, the cells being connected to the heat conducting plate in a heat conducting manner. In the heat conducting plate, a channel structure for a heat conducting medium is provided. In the region of the poles of the single cells, the heat conducting plate comprises bores through which the poles of the single cells extend.
Abstract:
A battery comprising a plurality of individual cells that are formed by heat conducting reciprocal housing plates that are positioned at a distance from each other at least in sections so as to form fluid-permeable flow-through channels. A fluid flow guiding unit is disposed on at least one edge side of the individual cell housing of each individual cell.
Abstract:
