Abstract

A liquid electrolyte fuel cell system (60) comprises at least two fuel cell stacks (20a, 20b), each comprising a plurality of fuel cells, each fuel cell comprising a liquid electrolyte chamber between opposed electrodes, the electrodes being an anode and a cathode. At least one fuel cell stack (20a) is arranged to operate at an elevated temperature such as 65°C, and at least one fuel cell stack (20b) is arranged to operate at a temperature below the elevated temperature, such as 35°C. The system (60) comprises a heat exchanger (62; 64) to transfer heat from at least one fuel cell stack (20a) at the elevated temperature to at least one fuel cell stack (20b) at the lower temperature. This may be achieved by heat exchange between the respective electrolytes.
