Unit dosing oxygen into gas generator for fuel cell, comprises perforated concentric cylindrical pipes which can be rotated relative to each other

摘要

The unit includes two concentric cylindrical pipe sections (1, 6). Each has openings (2, 7, 2a, 7a) in its surfaces (5a, 5b). The pipe sections can be turned relative to each other, allowing the oxygen-containing medium (A) to flow into the inner cylindrical pipe section (1).
