| 摘要 |
The invention concerns a device comprising a rectilinear manifold (20) wherein emerge the outlets (12) of cells (2) and provided with a pressure regulator (29), a sampling tube (23) extending in rectilinear manner inside the manifold and which is connected outside the latter to a recovery tank (24) wherein it emerges through an outlet (25) located at a height <i>h</i> relative to its axis, at least a nozzle (26 or 27) presented by the tube and calibrated such that the residual pressure maintained by the pressure regulator is higher than the height of the column of water corresponding to the height <i>h</i>. The invention is applicable to air-hydrogen cells. |
