Randall F Gahn, Norman H Hagedorn: Negative electrode catalyst for the iron chromium REDOX energy storage system. The United States of America represented by the Administrator of the National Aeronautics and Space Administration, James A Mackin, John R Manning, September 24, 1985: US04543302 (27 worldwide citation)

A REDOX cell to operate at elevated temperatures and utilizing the same two metal couples in each of the two reactant fluids is disclosed. Each fluid includes a bismuth salt and may also include a lead salt. A low cost, cation permselective membrane separates the reactant fluids.
