Manganese dioxide was evaluated for use as the positive electrode in fuel cell-secondary battery composite systems. Electrodes were fabricated by coating nickel foam with a mixture of MnO2 and carbon black, and the charge/discharge behaviour studied in three systems: as a secondary battery positive...
