摘要： A battery includes a stacked arrangement of electrochemical cells. Each electrochemical cell is free of a cell housing and includes a bipolar plate having a substrate, a first active material layer formed on a first surface of the substrate, and a second active material layer formed on a second surface of the substrate. Each cell includes a solid electrolyte layer that encapsulates at least one of the active material layers, and an edge insulating device that is disposed between the peripheral edges of the substrates of each pair of adjacent cells. A support frame surrounds the cell stack and is configured to receive and support the outer peripheral edge of the edge insulating device of each cell.

摘要： The invention relates to a method for the commissioning of a fuel cell stack (1), in which the fuel cell stack (1) is commissioned and is supplied with different media during the commissioning and/or operation thereof, the operating state of the fuel cell stack (1) is changed and at least one state variable of the fuel cell stack (1) is acquired. According to the invention, the acquired state variable is calculated in a chemical-physical model of the fuel cell stack (1) or of a fuel cell of the fuel cell stack (1), and at least one model parameter of the model is correspondingly updated. At least one new actuating variable for controlling the media supply and/or the load of the fuel cel stack (1) is subsequently derived from the at least one updated model parameter. The invention further relates to a device for carrying out the method.
