Abstract
A heat exchanger for a fuel cell is disclosed. The heat exchanger includes at least two tube bodies that are arranged at a distance from one another and are in each case structured so that a fluid can flow through internally and so that air can flow around externally. A water channel, through which water can flow fluidically separated from the fluid, is arranged in or on at least one tube body. At least one opening, via which the water channel communicates fluidically with an external environment of the at least one tube body, is provided on the at least one tube body. The at least one opening is arranged in the at least one tube body so that at least one of the tube bodies can be wetter with water, which is guided through the water channel and escapes the water channel through the at least one opening.
