Abstract
A hybrid redox fuel cell system includes a hybrid redox fuel cell and an electrochemical cell. The hybrid redox fuel cell includes an anode side through which hydrogen is flowed and a cathode side through which liquid electrolyte is flowed, the liquid electrolyte including a metal ion at a higher oxidation state and the metal ion at a lower oxidation state. An anode side of the electrochemical cell is fluidly connected to the cathode side of the hybrid redox fuel cell. At the hybrid redox fuel cell, power is generated by reducing the metal ion at the higher oxidation state to the lower oxidation state at the cathode side while oxidizing the reductant at the anode side. At the anode side of the electrochemical cell, the metal ion at the lower oxidation state is oxidized to the higher oxidation state while the power is generated.
