FLUID DISTRIBUTING DEVICE

摘要

Fluid distributing device, wherein a fluid comes into exchanging contact with a surface. The fluid can be, for example, a gas in an electrochemical cell, such as a fuel cell. In order to produce complicated channels in a particularly simple and inexpensive manner, in order to distribute a fluid of this kind as evenly as possible over the exchanging surface, it is proposed to construct channels of this type from a number of perforated plates (3, 4). In this case, the openings (8) are arranged such that, when the plates are positioned accurately on top of one another, the openings overlap partially. These channels are laterally sealed, so that accurate metering of the gases through the various channels is ensured and a sufficient pressure drop is ensured to discharge any moisture which may form.
