A fuel cell assembly (101) comprises an electrode (1601) in a reaction region, the assembly (101) configured with an electrolyte flow path (601) for flowing communication of an electrolyte with the electrode (1601); a supply device (1701) for controllably supplying a regeneration component to the electrolyte; and a monitor device (801) operable to monitor the oxidation state of the electrolyte. The electrolyte comprises a redox couple, the oxidation state of which changes with both reaction at the electrode (1601) and contact with the regeneration component. The monitor device (801) is configured to output a signal representative of the oxidation state of the electrolyte and the supply device (1701) is configured to be responsive to the output of the signal to control supply of the regeneration component to the electrolyte. |
