100 % power availability based on hybrid switch from battery to fuel cell. The EFOY & EFOY Pro fuel cell constantly monitors the charge status of the battery and automatically charges it. This means your application is always reliably supplied with power. The fuel cell produces power in any weather, at all times of the year, everywhere. The EFOY Pro’s high reliability in generating power reduces costs. Downtimes are prevented.
EFOY & EFOY Pro fuel cells supply off-grid power for months – without any user intervention. Our fuel cells use methanol – an alcohol with an extremely high energy density. Ten litres of methanol contain 11.1 kWh of energy. Four 28 litre fuel cartridges can power a 50 W device autonomously for about 26 weeks.
During operation, the sole by-products are small quantities of carbon dioxide and water. Thanks to environmentally friendly power generation, the EFOY & EFOY Pro can be used in nature reserves as well as in closed vehicles and rooms. The EFOY fuel cells are equally suitable for covert investigations, thanks to their low-vibration and quiet operation without heat generation.
EFOY & EFOY Pro fuel cells generate reliable power for periods of weeks or months, they are fully automatic and emission-free and they can be installed covertly and safe from vandalism. All SFC Energy AG fuel cells are based on DMFC (Direct Methanol Fuel Cell) technology. An environmentally friendly catalytic process is used to convert the alcohol methanol directly and efficiently into power without interim stages. As a result, this technology represents one of the cleanest options for generating power.
With a weight of 6-8 kg (13-18 lbs) and dimensions of 448 x 198 x 275 mm (17,6 x 7,8 x 10,8 in), the EFOY & EFOY Pro fits into any control cabinet and is easy to transport.
Batteries have very limited autonomy. Whether in a vehicle, on a construction site or in a control cabinet, if an application is supplied only by batteries, frequent battery changes and therefore the costs of keeping the application running are extremely high. With an EFOY Pro fuel cell, deep discharges of batteries can be avoided, increasing autonomy by many times, minimising downtimes and service intervals and therefore considerably reducing costs.
“A reliable power source”
There are many innovative solutions and technologies for surveillance on the market. However, without power, these solutions are useless. A reliable power source is the key to success.

The EFOY Pro fuel cells are available in various performance categories, with outputs ranging from 45 W for small-scale power systems to a 500 W module for UPS solutions. The EFOY JUPITER hydrogen fuel cell serves as a back-up power supply solution and ensures power supply in the event of a grid failure.
