(NL1004513-C2)      The arrangement is applicable to a system with at least two molten carbonate or solid oxide fuel cell stacks (1,2,3). The cathode flows (14) of the stacks are connected in series while the anode flows (25) are connected in parallel. All the stacks have a reforming device for a hydrocarbon fuel. Anode gas is recycled (24) from the stack outlets to the inlets.    The cathode streams between the stacks are cooled by, for example, adding streams of cool air to them. Thus the cathode inlet temperatures can be controlled by relatively inexpensive low temperature air valves.    ADVANTAGE -   Increases efficiency is system which allows the use of stacks of a single design whilst retaining the advantages of series connection of the oxidant streams and giving low per pass fuel utilisation.
