摘要： Operating cycles for fuel cell systems, particularly solid oxide fuel cell (SOFC) systems, include recirculation of at least a portion of exhaust gases (17) emitted from the anode and/or cathode sides of the fuel cell stack (8) and mixing them gases with fresh reactants (2, 10) before supply to the fuel cell. To control the temperature of the stack, bypass loops are used to allow a proportion of the oxidant to bypass an oxidant preheater (12) and/or the fuel cell stack. The relative proportions of fresh and recirculated fuel are maintained constant during normal operation of the system by controlling an ejector (24) which powers recirculation of the exhaust from the anode side of the stack.
