    摘要： A fuel gas supply apparatus for a fuel cell includes: a plurality of fuel gas supply sources, a plurality of fuel gas supply lines, a plurality of first valves disposed on the plurality of fuel gas supply lines, the first valves being capable of opening and closing on the basis of a pressure of a mixed gas of the plurality of fuel gases or a pressure of a mixed gas tank. A mixed gas supply line is provided for supplying the mixed gas containing at least one of the plurality of fuel gases to the fuel cell. The plurality of first valves open if the pressure of the mixed gas of the plurality of fuel gases or the pressure of the mixed gas tank becomes equal to or lower than a setting pressure, and the setting pressure is set to be different for each of the plurality of first valves.

    摘要： Systems and methods are provided for assembling and operating an electrode assembly for a redox flow battery system. In one example, the electrode assembly may include an inflatable housing in which a negative electrode spacer and a positive electrode may be positioned, wherein the inflatable housing may inflate responsive to applied internal pressure during operation of the redox flow battery system. In some examples, the electrode assembly may be assembled via roll-to-roll processing and may be mechanically and fluidically coupled to electrode assemblies of like configuration. In this way, tolerance stacking may be decreased, processing may be simplified, and costs may be reduced relative to molding-based processes for electrode assembly manufacturing.

    摘要： A redox flow battery includes a cell, an electrolyte tank configured to store an electrolyte supplied to the cell, and a circulation mechanism. The circulation mechanism includes a suction pipe configured to suck up the electrolyte from an open end thereof in the electrolyte to above an in-tank liquid level of the electrolyte in the electrolyte tank, a circulation pump, an extrusion pipe, and a return pipe. HL/H0 is greater than or equal to 0.4 and HS is less than or equal to HL, where H0 is a height from an inner bottom surface of the electrolyte tank to the in-tank liquid level, HL is a length from the open end of the suction pipe to the in-tank liquid level, and HS is a height from the in-tank liquid level to a center of a suction port of the circulation pump.
