INDIRECT REDOX FUEL CELL INCLUDING TUNGSTEN POLYOXOMETALATE CONTAINING CATHOLYTE

摘要

PROBLEM TO BE SOLVED: To provide an improved catholyte solution for use in a redox fuel cell.SOLUTION: A redox fuel cell includes a non-volatile catholyte solution comprising a polyoxometalate redox couple which is at least partially reduced at a cathode 3 in operation of a cell and at least partially re-generated by reaction with an oxidant, such as air, oxygen and peroxides, in a reaction chamber 5 after such reduction.SELECTED DRAWING: Figure 1
