A redox flow battery including: a cathode cell including a cathode, a catholyte, and a bipolar plate; an anode cell including an anode, an anolyte, and a bipolar plate; and an ion exchange membrane interposed between the cathode cell and the anode cell, wherein at least one of the cathode and the anode comprises a carbon-coated metal foam, wherein the ion exchange membrane includes a porous substrate and a polymer disposed in pores of the porous substrate, wherein the polymer is a polymerization product of a composition for preparing an ion exchange membrane, and wherein the composition for preparing an ion exchange membrane includes a first aromatic vinyl monomer including a halogenated alkyl group or a quaternary ammonium group, and wherein the bipolar plate includes Ni, Cu, Fe, Cr, Al, W, Ti, or a mixture thereof, or an alloy thereof.

Redox flow battery

A redox flow battery. A metal-ligand coordination compound including an aromatic ligand that contains an electron withdrawing group is used as the catholyte and/or the anolyte so that a redox flow battery having high energy density and excellent charge/discharge efficiency may be provided.

A fuel cell power management system and an anti-islanding method using the power management system. The power management system includes a fuel cell to generate direct current (DC) power, a power conditioning system (PCS) to generate alternating current (AC) power from the DC power generated by the fuel cell, a power grid that is connected to the PCS, a detector to detect a change in the AC power flowing from an output line of the PCS, and a controller to control the connection between the PCS and the power grid, according to the result of the detection.
