Abstract
An offset control arrangement is disclosed for controlling voltage values in a fuel cell system including an anode side, a cathode side and an electrolyte between the anode side and the cathode side. The fuel cell system can include at least one fuel cell array of at least two fuel cells, and at least one load for performing load function. The offset control arrangement can include voltage monitoring for monitoring an input voltage of the load, a control processor for processing the monitoring information, and at least one offsetting source in serial connection to the at least one fuel cell array, with a power level of the offsetting source being substantially low compared to the power level of the fuel cell array, and the offsetting source being arranged to perform at least unidirectional shifting of fuel cell array output voltage.
