EFOY Pro
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.

EFOY Pro Benefits
Clean energy, everywhere
EFOY fuel cells are the ideal power generators for a wide range of stationary and mobile applications. They generate electricity reliably for weeks and months without user intervention. The EFOY direct methanol fuel cells are available as EFOY and EFOY Pro models with an output of up to 125 W depending on the power requirements and user requirements. Our EFOY and EFOY Pro models are designed for different application purposes.
The EFOY models are designed for temporary applications with low operating hours and are used as a back-up power supply for grid-connected or solar-powered hybrid installations. The EFOY Pro series is ideal for continuous operation and can also be used in hybrid operation. You can operate your application completely autonomously with the EFOY Pro, compensate for low solar output and use smaller solar modules.
Model overview
Extend the run time with the EFOY Fuel Manager
The Fuel Manager (FM) allows you to operate several EFOY fuel cartridges with one EFOY. Depending on the model, two, four or eight fuel cartridges can be simultaneously connected. The Fuel Manager automatically switches from the current to the next full fuel cartridge and ensures a long self sufficiency without user intervention.
Remote Monitoring with EFOY Cloud
EFOY fuel cells are often used in remote locations and require the option of secure remote access. EFOY Cloud gives you access to your methanol fuel cells from anywhere so you can monitor continuous operation via laptop, tablet or smartphone. All you need for this is an Internet connection to your fuel cells.
EFOY energy solutions
EFOY Pro energy solutions combine power generation via EFOY Pro fuel cells and energy storage with batteries in a suitable housing. There is still sufficient space for customer-specific adaptations.
Quiet and environmentally friendly
Thanks to environmentally friendly power generation, the EFOY Pro can be used in nature reserves as well as in closed vehicles and rooms.
EFOY Pro
How it works
Environmentally friendly
The EFOY Pro charges the batteries fully automatically. The integrated charge controller permanently monitors the charge status of the battery. When required, the EFOY Pro is started automatically and turned off again when the battery has been charged. This means not only will you always have full power reserves, but your batteries will also last much longer because continuous charging prevents deep discharge. 230 V devices can be operated when an inverter is used.
The EFOY fuel cells are based on DMFC (Direct Methanol Fuel Cell) technology. They generate power from the fuel in the fuel cartridge (methanol), complemented by oxygen from the air. Methanol is directly converted into power. In addition to power, all this creates is waste heat and water vapour with a little carbon dioxide. This is very environmentally friendly.
The power generating principle
of EFOY fuel cells
The EFOY fuel cell converts chemical energy into electrical energy without interim stages, without moving parts and without much loss of efficiency. That is why it is such an efficient power generator. The innovative and patented developments of the EFOY fuel cell enable a miniaturised set-up, high performance, a long service life and a low weight. Using the technology developed in-house, SFC has acquired a unique technological and competitive edge in the field of fuel cell systems for off-grid equipment with the EFOY fuel cells.
The hybrid principle of EFOY fuel cells
Of course, the EFOY fuel cells also work with other power generators. In combination with solar modules, for example, they only turn on when the solar module cannot deliver sufficient power during bad weather.
The principle of water recovery
The stack is the power-generating core of the EFOY fuel cells. It consists of individual cells, each of which is set up to include an anode, a cathode and a membrane. The membrane, as an electrolyte, separates anode from cathode. Positively charged, electric particles, so-called protons, can diffuse through the membrane. On the side of the anode, water and methanol are added, on the side of the cathode, oxygen is taken from the ambient air. In the reaction on the anode, H+ ions and free electrons are created, as well as the reaction product carbon dioxide (CO2). The protons can cross the membrane. The electrons, however, have to travel to the cathode side via a connected electric circuit during which they generate power. On the cathode, the H+ ions, the oxygen from the air and the electrons are converted into water vapour. This makes the EFOY fuel cell very environmentally friendly.
