SYSTEM FOR GENERATING ELECTRICAL POWER

The invention relates to a system for generating electric power, which has a series of PEM cell stack modules (1), supplied by a source of hydrogen (8), the pressure of which must be adjusted preferably to almost atmospheric pressure. The system also includes a subsystem for controlling and monitoring each stack, which can activate and deactivate same individually. The control and monitoring subsystem can monitor the modules by receiving, from each module, the signal from an ammeter and a voltmeter of the stack, as well as from a subsystem for detecting cell voltage for each cell of the module stack. Said reception can take place in a first level of the control and monitoring subsystem, via local controllers for each module, which are coordinated at a higher level by a single higher control unit. A cell management subsystem uses said signals to verify that the cell is not exposed to corrosion currents.
