There is provided a fuel cell cathode electrode, comprising a porous skeletal medium, the surface of which medium is modified or otherwise arranged or constructed to induce enhanced activated behaviour, wherein the enhanced activated behaviour is induced by means of increasing the surface area for a given volume of the electrode and/or by increasing the number and/or availability of reactive sites on the electrode. A fuel cell having such a cathode electrode, a method of manufacturing such a cathode electrode, and use of such a cathode electrode in a fuel cell is also disclosed.

Cathode electrode material including a porous skeletal medium comprising a modified surface

This invention provides a redox fuel cell comprising an anode and a cathode separated by an ion selective polymer electrolyte membrane; means for supplying a fuel to the anode region of the cell; means for supplying an oxidant to the cathode region of the cell; means for providing an electrical circuit between the anode and the cathode; a non-volatile catholyte solution flowing fluid communication with the cathode, the catholyte solution comprising a polyoxometallate redox couple being at least partially reduced at the cathode in operation of the cell, and at least partially re-generated by reaction with the oxidant after such reduction at the cathode, the catholyte solution comprising at least about 0.075M of the said polyoxometallate, and a vanadium (IV) compound.
