FIELD: heating.
SUBSTANCE: group of inventions relates to fuel cells. The complex of fuel cell and a method of controlling it is proposed. The complex of fuel cell comprises: a fuel cell made of a plurality of complete electricity-generating elements, the measuring unit of the cell voltage, detecting the negative voltage in any of the electricity-generating elements, the control unit controlling the output electric power of the fuel cell, and the unit determining the total value of current, determining the total value of current obtained by integrating in time of the output current of the fuel cell. The control unit previously stores the correlation between the integrated values of the current and current density that are allowable for this fuel cell in the period during which the negative voltage is generated. If the negative voltage is detected, the control unit performs the process of limiting the output to limit the electrical power output of the fuel cell in order to get into the allowable working range defined by the allowable total current values and the allowable values of current densities of the said correlation.
EFFECT: improving the efficiency of electricity generating cell.
