Heat exchanger for feeding through fluids/gases has multiple parallel plates set apart to produce modules forming two groups of modules with a different fluid flow path each module having a fluid inflow and outflow.

摘要

Each rectangular metal or ceramic plate's (10) surface has a 3D relief structure (12) in order to magnify the surface coming into contact with a fluid. On the outside of each plate there are four fluid-feeding devices (11) in the form of tacked metal sheets. These devices can be half or full rings and have a dosing capability. An Independent claim is also included for a fuel cell system with a heat exchanger.
