| 摘要 |
A redox fuel cell comprising a catholyte solution comprising at least one non-volatile catholyte component, the catholyte solution comprising a redox mediator couple; and a regeneration zone separate from the membrane electrode assemblies of the fuel cell, the means for supplying an oxidant to the fuel cell being adapted to supply the oxidant to the regeneration zone, the volume of catholyte solution in the regeneration zone being from about 25% to about 90% of the total combined volume of catholyte solution in the regeneration zone and the cathode chambers of the fuel cell.
