Description

Technical Field

[0001] This utility model relates to the field of metal fuel cell technology, and in particular to a multifunctional metal-air fuel cell device. Background Technology

[0002] Lighting equipment plays an important role in outdoor camping fires or emergency rescues, especially in situations where there is insufficient light at night. However, most camping lights or emergency rescue lights on the market currently use conventional rechargeable lithium batteries or disposable dry batteries, which have the problems of short battery life and insufficient storage time.

[0003] Magnesium-air batteries, as a type of metal-air battery, possess a high open-circuit voltage. Magnesium metal also boasts a high electrochemical equivalent (2.2 Ah / g), second only to lithium and aluminum, but its density is only 1.74 g / cm³, lower than aluminum-hydrogen. Therefore, magnesium-air fuel cells exhibit high specific energy. Currently, the energy density of magnesium-air fuel cells has reached 800 Wh / kg, equivalent to 30 times that of lead-acid batteries used in automobiles. These advantages make them highly promising for charging portable electronic devices and providing long-term lighting.

[0004] As an ideal solution, magnesium-air fuel cells can provide a clean, environmentally friendly, and stable power supply. During the use of a metal-air battery, metal is consumed as fuel, along with atmospheric oxygen, producing metal hydroxides. This process produces no polluting gases or noise, and magnesium-air batteries are also quite convenient to use and maintain. Utility Model Content
