ABSTRACT:
In a fuel cell power plant comprising a plurality of stacks of molten carbonate fuel cells the CO.sub.2 produced at the anodes of the cells is combined with the process air for the cathode side of the stacks. The CO.sub.2 rich mixture is fed from stack to stack in series through the cathode sides thereof with heat being removed from the cathode side exhaust streams between consecutive stacks. This process improves cell performance by increasing the CO.sub.2 partial pressure within the stacks. The process also makes it possible to reduce the required heat exchanger heat transfer area needed to cool the cell exhaust products.
