Prototype secondary iron/air cells comprising pressed-type iron electrodes and oxygen electrodes of some oxide pyrochlores have been assembled and subjected to electrochemical charge/discharge tests for over 150 cycles at various load currents. The cells are found to exhibit little deterioration in performance. Oxygen electrodes using PbBiRu2O7-y oxide pyrochlores are superior to those with Pb2Ir2O7-y, except under high-load currents.
