A flow arrangement for fuel cell stacks connects fuel cell stacks into fuel stack groups having a number of fuel cell stacks connected in parallel by their anode and cathode parts so that the inlet of the anode part of each fuel cell stack group is in connection with an inlet manifold common to these and that the exhaust of the anode part of each group is connected with an exhaust manifold. Further, the inlet of the cathode part of each group is connected with a cathode part manifold and the exhaust of the cathode part of each group is connected with a cathode part exhaust common to these. The fuel cell stacks are connected in series by their cathode side flows. A by-pass channel system provides flow connection between at least one cathode part manifold subsequent to the fuel cell stack group and the first part of the cathode flow channel system, at a position located prior to the heat exchanger in the flow direction of the gas. |
