摘要： An electrochemical cell includes a flow chamber disposed between two plate elements and having a flow inlet and a flow outlet for a flow medium permeating the flow chamber and defining a main flow direction of the flow medium between the flow inlet and the flow outlet. One of the plate elements has protrusions for supporting the plate element on the other plate element in a regular grid structure, between which a network of flow channels passing through the flow chamber runs in at least one flow channel direction. The regular grid structure is configured in such a way that the grid of the flow channels has two or more flow channel directions each enclosing an angle differing from zero degrees relative to the main flow direction of the flow medium.

摘要： A spring contact sheet (1) for the transfer of current between two components (10,11) of an electrochemical battery (21) has a sheet (2) with a number of spring tabs (3) bent out of the plane of the sheet (8).

摘要： A leak in the membrane of a fuel cell leads to an uncontrolled and heat-generating reaction which can destroy the fuel cell. A method for recognition of a leak in a fuel cell is disclosed which leads to an automatic closing down of the fuel cell without a safety device. The anode gas chamber of the fuel cell is treated with a first test gas and the cathode gas chamber of the fuel cell is treated with a second test gas. The cell voltage of the fuel cell measured and the change with time in the cell voltage is monitored. A gas with a hydrogen content of 0.1 to 20 vol. % is used as first test gas and a gas with an oxygen content of 0.1 to 30 vol. % is used as second test gas.

摘要： The invention relates to a fluid-cooled fuel cell, in which the cell surfaces are supplied with reaction media via axial supply ducts and radial distribution ducts, the distribution ducts being located in the cell surface and running along the edge of the cell surface, with the open side toward the active surface.According to the invention, the supply and distribution ducts in a fuel-cell stack are arranged such that distribution ducts are arranged in the edge region of the cell surfaces, as a result of stacking and staggering, in such a way that the inlet of the medium to the cell surface along a distribution duct is not carried out in a point-like manner, and that the entire cell surface is uniformly supplied with medium.

摘要： A fuel cell assembly includes a fuel cell configuration having a solid electrolyte-based fuel cell with terminal contacts tapping an electrical voltage from the fuel cell configuration between which the fuel cell is disposed. An assembly has an electrically conductive component and another component disposed between a first terminal contact and the electrically conductive component on the side of the first terminal contact away from the fuel cell and has a lower electrical conductivity than that thereof. A supply duct transports a fluid medium connecting the first terminal contact to the electrically conductive component through the other component. The electrically conductive component is connected to the first terminal contact and/or a voltage supply adjusting an electrical potential on the electrically conductive component to an electrical potential on the first terminal contact. There is a maximum potential difference of 3 volts between the electrically conductive component and the first terminal contact.

摘要： A planar, rectangular and water-cooled fuel cell includes a cooling element with a cooling chamber through which cooling water flows during the operation of the fuel cell. Cooling water does not flow through the cooling chamber in a homogeneous manner, normally resulting in local heating of the fuel cell in regions through which the cooling water flows through less frequently. A fuel cell is provided with a cooling element which includes an essentially rectangular cooling chamber with four corner regions, whereby the opening of the coolant flow is arranged in the first corner, the opening of a first coolant flow is arranged in a second corner and a second coolant flow is disposed in a third corner. The first coolant flow has a cross section Q1 on the narrowest point thereof and the second coolant flow has a cross section Q2 on the narrowest point thereof, the ratio of Q1/Q2 being 7-25.
