Description

technical field [0001] The present invention relates to a device for directly converting chemical energy into electrical energy, in particular to a metal fuel cell using an aqueous solution as an electrolyte, and in particular to a device for outputting high-power electrical energy with a metal-air battery. Background technique [0002] Metal-air battery is a new type of high-energy chemical power source. It uses magnesium-aluminum-based alloy as negative electrode, air electrode as positive electrode, and neutral aqueous solution as electrolyte. During battery operation, it consumes magnesium-aluminum alloy negative electrode and oxygen in the air for external output. electrical energy. The metal-air battery does not need to be charged, and the battery can continue to run by updating the consumed magnesium-aluminum alloy anode material during the operation of the battery, so it is also called a metal fuel cell. Neutral metal-air batteries use brine or seawater as the elect...
