Gemeco unveils EFOY Fuel Cell for Mobile Applications

EFOY Fuel Cells

Gemeco presents the most innovative 12-volt charging technology available – the EFOY Comfort Series Fuel Cell. A fuel cell is a device that uses a source of fuel and an oxidant to create electricity from an electro-chemical process. In principle, this is the reverse of electrolysis. It might sound like something right out of a recent science fiction movie but this silent, eco-friendly technology from EFOY has actually been around for more than 10 years, with over 40,000 fuel cells currently in service worldwide.

The EFOY Comfort system is a lightweight (under 20 pounds) and highly compact (18 x 12 x 8 inches) power generator that automatically maintains the charge level of any 12-volt system without the noise and fumes of a typical gas powered generator. It exhausts water and warm air, so it’s safe for use in confined areas that are typical of a marine application. Installing an EFOY fuel cell is truly as simple as a 4-wire connection to the 12-volt electric system, attaching the included water drain hose and then connecting the fuel cartridge.

In minutes you have a fully capable solid-state generator on-line. There is no complicated programming required, and the built-in monitoring circuitry automatically starts and stops the fuel cell to maintain a full charge. Battery charging does not get any easier or more efficient than this.

  • Three models offer 80, 140 or 210 Ah capability per day
