1. A redox fuel cell comprising:
- an anode region comprising an anode and a cathode region comprising a cathode, said regions being separated by an ion selective polymer electrolyte membrane;
a fuel passage through which fuel is supplied to the anode region of the cell;
an oxidant inlet that supplies an oxidant to the cathode region of the cell;
an electrical circuit between the anode and the cathode; and
a catholyte solution flowing in fluid communication with the cathode, the catholyte solution comprising a modified ferrocene species, the modified ferrocene species being at least partially reduced at the cathode in operation of the cell, and at least partially re-generated by reaction with the oxidant isolated from the anode region after said reduction at the cathode.
