(10) comprises at least one fuel cell module (12), each fuel cell module (12) comprises a plurality of fuel cells (14). Each fuel cell module (12) is hollow and defines a chamber (16). Each fuel cell module (12) is arranged within an inner vessel (24) and the inner vessel (24) is arranged within an outer pressure vessel (28). Means (32) to supply oxidant is arranged to supply oxidant to the space (26) within the inner vessel (24) so as to supply oxidant to the cathode electrodes (22). Means (34) to supply fuel is arranged to supply fuel to the chamber (16) in each fuel cell module (12) so to supply fuel to the anode electrodes (18). The outer pressure vessel (24) is protected from the high temperature environment of the fuel cells (14) by the inner vessel (24). The outer pressure vessel (28) forms the main pressure containment of the arrangement and operates at a lower temperature and operates with a greater safety margin than a single pressure vessel arrangement. |
