Hydra Light HydraCell fuel cell technology

HydraCell, a fuel cell technology developed by Hydra Light, can generate its own power when activated by dipping in water.

When dipped in water, the moistened, salt-impregnated bridge material allows a reaction to start between the magnesium core and the oxygen in the air, initiating an electrochemical reaction and releasing electrons. The electrons are collected by the proprietary carbon membrane cathode and converted into usable DC power. HydraCells are claimed to maintain full power output for the entire life of the cell, unlike conventional batteries that slowly diminish in power.

When kept properly sealed and dry, the fuel cells can be stored for 25 years or more. They are activated to full capacity simply by dipping in water for 15 s to hydrate the bridge material. Once activated, the cells will operate continuously under load, requiring only periodic rehydration.

Potential applications include: emergency preparation, disaster relief, NGO and aid agencies, off-grid communities, lifestyle and outdoor enthusiasts, and the security, military, automotive and marine sectors.

The technology is suited to remote communities or areas with intermittent traditional power sources. The HydraCell generates power to replace disposable batteries, kerosene or candles, and generates USB power to charge phones and power USB devices.
