Benefits of an EFOY Pro fuel cell

Reasons to use our fuel cells

Conventional power sources are often unreliable or offer only short periods of supply. Solar-powered systems cannot guarantee a reliable power supply throughout the whole year, batteries have very limited autonomy and generators produce harmful emissions. EFOY Pro fuel cells are the perfect power generator, meeting all requirements for stationary and mobile applications.

100% reliable

100 % power availability based on hybrid switch from battery to fuel cell. The 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 EFOY Pro 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.

Long operating life, maintenance-free

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. Two 28 litre fuel cartridges can power a 25 W device autonomously for about 15 weeks. Maintenance of the EFOY Pro fuel cells is not required.

Quiet and environmentally friendly

During operation, the sole by-products are small quantities of carbon dioxide and water. Thanks to environmentally friendly power generation, the EFOY Pro can be used in nature reserves as well as in closed vehicles and rooms. The EFOY Pro fuel cells are equally suitable for covert investigations, thanks to their low-vibration and quiet operation without heat generation.

The cleanest way of producing energy

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.

To the technology

Lightweight and compact

With a weight of only 9 kg (20 lbs) and dimensions of 43 x 19 x 28 cm (17 x 8 x 11 in), the EFOY Pro fits into any control cabinet and is easy to transport.

Remote monitoring

The EFOY Pro fuel cell can be monitored and controlled via a modem. It notifies the user of upcoming fuel cartridge replacements, ensures planning safety and reduces the need for administration and maintenance.

Reduced operating costs

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.
