The hybrid reversible hydrogen-vanadium fuel cell [1,2] offers a feasible solution for storing electrical energy from the grid or intermittent renewable energy sources such as wind and solar. This system is an attractive alternative to the all-vanadium system due to the 50% reduction in the amount of vanadium solution required. This two-phase hybrid system also allows cross-over species to be separated and reused. In this presentation, the performance (cell voltage and power density versus current density and self-discharge rate) of this system at elevated temperatures (40^oC and 50^oC) will be discussed.
