The object of the invention is an arrangement for adjusting an arrangement for adjusting current values in a fuel cell system for producing electricity with fuel cells, each fuel cell in the fuel cell system comprises an anode side 100, a cathode side 102 and an electrolyte 104 between the anode side and the cathode side, and the fuel cell system comprises at least two electrically serial connected individual fuel cell stacks or groups of stacks, each said stack 103 comprising at least one fuel cell. The arrangement for adjusting current values in the fuel cell system comprises means for drawing the major part of the current from the at least one serial connection, at least one adjusting circuit 112 for adjusting current values of said individual fuel cell stacks or groups of stacks within the serial connection, integration means 116, 124 for integrating the at least one adjusting circuit with the individual fuel cell stacks or groups of stacks for arranging a small compensation current, compared to the major part of the current, to pass via the at least one adjusting circuit, and the at least one adjusting circuit 112 comprises means for controlling the small compensation current in the at least one fuel cell stack 103. |
