Abstract: A fuel cell stack, having fuel cells stacked in a stacking direction, each of which has a plate-shaped form extending in a first and second transverse directions, as viewed orthogonally in relation to the stacking direction. The fuel cells have a stack of: an anode-side bipolar half-plate with a fuel channel structure for conducting fuel; an anode-side gas diffusion layer; a membrane-electrode unit, having electrolyte membrane and electrode layers arranged on either side of the electrolyte membrane forming an anode and cathode for electrochemical reaction of the fuel with an oxidizing agent; a cathode-side gas diffusion layer; a cathode-side bipolar half-plate with an oxidizing agent channel structure for conducting the oxidizing agent; and end plates at either end of the stack in the stacking direction. On the side of the stack, belt receptacles are mounted on the end plates, and belts are mounted over the belt receptacles clamping the stack.

Abstract: A fuel cell arrangement and a production method for a fuel cell stack which is stacked in a stacking direction and composed of a plurality of plate-shaped components stacked in a stacking direction, wherein the fuel cell has at least one end plate composed of a plurality of segments.

Abstract: The invention relates to a tensioning and holding apparatus (6) having at least one tensioning means (12a, 12b, 13a, 13b) for a cubic or cuboidal object (1) of variable geometry and/or dimensions that can be fixed by pretensioning, wherein the object has a respective end plate (4, 5) at two opposite ends. According to the object of the invention, this tensioning and holding apparatus should be able to be mounted particularly easily and be produced cost-effectively.

Abstract: Disclosed is a surgical targeting device for assisting placement of an elongated guidance member in a bone. The targeting device comprises a bottom portion having a dome-shaped convex outer surface and comprising a guidance through-hole extending along a guidance through-hole central axis for receiving the guidance member. A top portion of the targeting device is configured to be gripped by a tool. Further, a surgical system is disclosed which comprises the surgical targeting device.
