Abstract: A redox flow battery includes a positive-side electrode tank that stores an electrolytic solution to be circulated to a positive electrode chamber in which a positive electrode is accommodated; and a negative-side electrode tank that stores an electrolytic solution to be circulated to a negative electrode chamber in which a negative electrode is accommodated. Each electrolytic solution contains an active material and a mediator, and the active material is solid in each electrolytic solution. An electrolyte concentration in each electrolytic solution is adjusted such that a potential difference between an equilibrium potential of the active material and an equilibrium potential of the mediator is equal to or less than a predetermined potential difference.

Abstract: A fuel cell electrolyte includes: a porous member; and a proton conductive material supported by the porous member. The proton conductive material includes a metal ion, an oxoanion, and a proton coordination molecule. At least one of the oxoanion and the proton coordination molecule coordinates with the metal ion to provide a coordination polymer. A relative density is equal to or higher than 75%.

Abstract: A fuel cell electrode includes an intra-electrode proton conductor and a catalyst. The intra-electrode proton conductor contains a metal ion, an oxoanion, and a proton coordinating molecule, and at least one of an oxoanion and a proton coordinating molecule coordinates to the metal ion to form a coordination polymer. The intra-electrode proton conductor is disposed in contact with the catalyst. For example, the catalyst is covered with the intra-electrode proton conductor.
