摘要： Described herein are methods, air cathodes or electrochemical cell systems configured to reduce or alleviate leakage of electrolyte within air cathodes. A method for electrolyte leakage management in an electrochemical cell system includes: configuring a plurality of air cathodes within an electrochemical cell system, each of the plurality of air cathodes comprising a frame, a membrane oxygen electrode attached to the frame to define a sealed interior cavity, an air inlet communicative with the interior cavity, a liquid outlet communicative with the interior cavity; positioning the liquid outlet lower than the air inlet; and draining electrolyte leakage from the interior cavity through the liquid outlet. An electrochemical cell system configured for electrolyte leakage management includes: a housing; an electrolyte disposed in the housing; a metallic material, when positioned in the first spaces, forms one or more discharging anodes; one or more charging anodes and one or more charging cathodes at least partially immersed in the electrolyte; and one or more air cathodes immersed in the electrolyte and one or more first spaces between the oxygen cathodes, each of the one or more air cathodes comprising 1) a frame, 2) a membrane oxygen electrode attached to the frame to define an interior cavity, 3) an air inlet communicative with the interior cavity, 4) an air outlet communicative with the interior cavity, 5) a liquid outlet communicative with the interior cavity, 6) the liquid outlet positioned lower than the air inlet.

摘要： Aluminum-air battery units and stacks are provided with frames configured to mechanically support the anode of each unit, within a housing configured to support the frame and the air cathode(s) mechanically, sealably hold the electrolyte within the housing and in fluid communication with openings in the housing—forming one or two sided electrochemical cell in each unit. The frame comprises a protective strap configured to protect edges of the rectangular anode against corrosion by the electrolyte during operation, and also an external trapezoid shape that is configured to press the protective strap against the edges of the rectangular anode upon insertion of the frame with the anode into the housing. Various embodiments comprise, spacers between the anode and cathodes and grids supporting airways to the cathodes. In disclosed configurations, anode may be replaced after electrolyte evacuation while maintaining the stack sealed and quickly ready for renewed operation.

The upper center of a housing has an upper hole and the lower center of a housing has a bottom hole. There is a slope inclined toward the inside in a cavity. There is a lower through hole at the lowest end of a slope. A lower through hole is communicated with a bottom hole of a housing. Both sides of a bottom hole and an upper hole have a mating surface groove, in which a sealing ring of a housing is placed. An upper sealing ring is fixed on a sealing plug. A sealing plug, an alloy plate, and an upper copper electrode are connected by a screw of an alloy plate. A battery cover is covered with a sealing plug. The middle of a sealing plug is provided with a middle hole corresponding to an upper hole of a housing, in which there is a downward upper through hole. When a sealing plug is inserted into the upper part of a housing, a closed space is formed inside a housing.
