Abstract: A control system is intended to be tailored to a fuel-cell stack. This fuel-cell stack includes a plurality of cells connected in series between a first terminal and a second terminal. This system includes a central control unit and an electronic bypass device including a plurality of separate electrical bypass units, each electrical bypass unit being connected in parallel to at least one separate cell of the fuel-cell stack, in order to control its discharge on startup and shutdown of the stack and thus to avoid the creation of inverse electrical potentials and to limit the presence of residual potentials.

Abstract: A method for automatically determining the resistance of the respiratory system of a spontaneously breathing intubated patient. The method includes measuring flow (V?) and airway pressure (Paw)) as a function of time; determining the airway pressure at the end of the occlusion period as end of occlusion airway pressure Paw(tc)=Poccl; analyzing a time 5 dependence of the flow starting at the end of the occlusion period to determine a transition time td at which the slope of the flow changes from a first high value to a second lower value; determining the flow at the transition time as transition time flow V?(td)=V?peak and determining the airway pressure at the transition time as transition time pressure Paw(td); and calculating the resistance on the basis of the ratio of an estimated driving pressure at the transition time Pdrv(td) and the transition time flow V?peak.
