%X <p>The H<sub>2</sub>-Ce redox flow cell is optimized using commercially-available cell materials. Cell performance is found to be sensitive to the upper charge cutoff voltage, membrane boiling pretreatment, methanesulfonic-acid concentration, (+) electrode surface area and flow pattern, and operating temperature. Performance is relatively insensitive to membrane thickness, Cerium concentration, and all features of the (−) electrode including hydrogen flow. Cell performance appears to be limited by mass transport and kinetics in the cerium (+) electrode. Maximum discharge power of 895&nbsp;mW&nbsp;cm<sup>−2</sup> was observed at 60&nbsp;°C; an energy efficiency of 90% was achieved at 50&nbsp;°C. The H<sub>2</sub>-Ce cell is promising for energy storage assuming one can optimize Ce reaction kinetics and electrolyte.</p>
