ASFC_Energy_logo_cmykdd-Mission offers a range of power solution for military and law enforcement applications through its partner SFC energy. These are methanol fuel cells that offer a high power output generating very little sound with no emissions other than water vapour.

Safe use

SFC solutions are environmentally friendly and contain no hazardous components. They all are safety-tested and meet international security standards.

Long autonomy

Award winning technology allows soldiers to transport a lot of power with very little weight and volume. No need to carry spare batteries. SFC fuel cells run on liquid methanol, a fuel with superior energy density. Ten liters of methanol, weighing a mere 8.4 kg, generate 11.1 kilowatt hours. Two 28 liter fuel cartridges can power a 25 watt device for more than 100 days without any user intervention.

Remote Monitoring

SFC fuel cells can be remote monitored. The fuel cell will inform the user in time when a fuel cartridge needs to be replaced. This enables a covert power supply, provides planning security, and reduces administrative and maintenance costs while ensuring that the system will always run reliably.

Lightweight and Compact

All SFC fuel cells are lightweight and compact. Due to their small size, SFC fuel cells can be carried by one single person. SFC fuel cells are interoperable and can easily be integrated into existing systems to extend runtimes.

Quiet and Emission-Free

SFC fuel cells generate hardly any detectable signature. They are the ideal solution for covert and tactical power supply scenarios, working without detectable vibration, noise, exhaust or heat. SFC fuel cells produce no harmful emissions. In operation, they only emit carbon dioxide and water in small quantities. Thanks to their environmental friendliness they can be operated in nature preserves or inside vehicles and closed rooms.

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.
