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 produce electricity from the fuel in the fuel cartridges and from the oxygen in the air. In operation, the only by products are waste heat and water vapor containing an insignificant amount of carbon dioxide. The whole process from source to application is extremely eco-friendly.

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.

The heart of the SFC fuel cells is the stack. The stack consists of several cells with an anode, a cathode, and a membrane that acts as an electrolyte, separating the anode and the cathode from each other. Positively charged electrical particles (protons) can permeate the membrane. Methanol and water are introduced on the anode side, while ambient oxygen enters the cathode side. H+ ions, free electrons and carbon dioxide arise on the anode side. The protons can permeate the membrane, while the electrons have to travel over an electrical circuit to the cathode side, thereby producing electrical current. H+ ions and oxygen generate water vapor on the cathode side, making SFC fuel cells an extremely environmentally friendly way to generate electricity.
