The frontispiece shows an external view of a pilot ZnCe redox flow cell stack nominally rated at 0.25 kA and 0.5 kW. The cell comprises > 60 bipolar titanium electrodes of approximate size 60 cm×40 cm for the negative zinc electrode compartment and a similar number of platinized titanium electrodes for the cerium compartment. The projected area of each electrode is 0.24 m 2 with an interelectrode gap of 2.5 mm. An expanded view of a single cell is also presented together with performance data showing the variation of the coulombic, voltage, and energy efficiency with the number of cycles. The development of ZnCe hybrid redox flow batteries is highlighted in the Review by Frank C. Walsh et al. on page 288 .
