1. A plate-like fluid container for conducting a fluid, usable for regulating the temperature of an electrochemical system, the fluid container comprising:
a metallic baseplate; and
a metallic channel plate adjacent to the baseplate, wherein the channel plate includes at least one channel for conducting the fluid formed by at least one channel-like depression which is directed away from the baseplate,
wherein the baseplate has at least one indentation directed in the direction of the channel plate, wherein in the base of the indentation, on that surface of the baseplate which faces the channel plate and outside the channel-like depressions of the channel plate, the baseplate lies on the channel plate and is welded to the channel plate, forming at least one weld seam running in the base of the indentation, wherein the weld seam on that side of the baseplate which faces away from the channel plate protrudes above regions of the baseplate which are directly adjacent to the weld seam, and wherein the indentation has a depth TG such that the baseplate outside the indentation protrudes above the weld seam running in the indentation and the depth TG is at least 0.1 mm and at most 70% of a height DS of the weld seam in at least one portion of the indentation.
