How Does It Work? – The Science of Metal-Air Fuel Cell Technology

At the core of this product lies cutting-edge Metal-Air Fuel Cell technology. It may sound complex, but the principle is remarkably simple.

When you add water (H₂O), it acts as an electrolyte, enabling a special metal plate inside the device to react with oxygen (O₂) from the air. This chemical reaction generates electricity. Unlike batteries that “store” power, this device “creates” it on the spot, meaning there’s no risk of self-discharge or degradation over time.
