Operating principle of SFC fuel cells

A fuel cell is an alternative power generator. It transforms chemical energy into electrical energy directly, with no intermediate steps, no moving parts, and with no significant loss in energy, making it a particularly efficient source of power. A lot of patented innovation has gone into our units, making SFC fuel cells a marvel of miniaturization, and a lightweight but high-powered, long-lasting performer. SFC’s proprietary technology has positioned SFC fuel cells to lead the field in fuel cell systems for off-grid and mobile applications.

How do SFC fuel cells work?

SFC fuel cells charge batteries fully automatically. The integrated charge controller permanently monitors the charge level of batteries. When the battery voltage drops below a predefined level, the fuel cell starts automatically and recharges the battery. Once the battery is charged, it switches off again. This results in reliable, continuous power, reduces the amount of batteries needed, and extends the lifetime of the batteries since deep discharge damages are prevented. Via an inverter, you can also operate 230 V devices.

SFC fuel cells use liquid fuel

Every SFC fuel cell employs DMFC (Direct Methanol Fuel Cell) technology which transforms methanol directly into electrical current. That's a real advantage, especially for mobile applications, because liquid methanol is easy to transport anywhere in practical SFC fuel cartridges.

SFC fuel cells and the hybrid principle

Of course it SFC fuel cells also work in hybrid with other power generators. For example, if a SFC fuel cell is connected to an application that also has solar to it, the fuel cell only charges the battery if solar does not deliver enough energy – due to bad weather.




In accordance with the CLP regulation, methanol is classified as toxic and highly flammable substance. Please refer to the safety data sheets for further information.
