EFOY Pro Fuel Cells are direct methanol fuel cells that operate using methanol as fuel. The methanol is stored in specially designed EFOY fuel cartridges, developed specifically for use with EFOY Fuel Cells. These cartridges can be replaced quickly, cleanly, and safely within seconds. Depending on your requirements, EFOY fuel cartridges are available in 5, 10, 28, and 60 litre sizes. The cartridge size can be selected to match the desired level of system autonomy.
Ultra-pure methanol is required to ensure the reliable operation of EFOY Pro Fuel Cells. To meet strict safety and quality standards, every filling process is monitored by SFC quality management. Maximum operating life can only be ensured when original EFOY fuel cartridges are used. Thanks to the high energy density of methanol, a large amount of energy can be stored in a compact space. This significantly increases the autonomy of off-grid applications.
EFOY fuel cartridges for industrial applications are available in capacities of 5, 10, 28, and 60 litres. The Fuel Manager (FM) enables multiple cartridges to be connected to a single EFOY system.
Depending on the model, two, four, or eight cartridges can be connected simultaneously. The Fuel Manager automatically switches from an empty cartridge to the next full one, ensuring extended operation without user intervention.

| EFOY Pro 1800 + FM2 | 2 x M28 | 52 days |
| EFOY Pro 1800 + FM4 | 4 x M28 | 104 days |
| EFOY Pro 1800 + FM8 | 8 x M28 | 208 days |
10 litres of methanol have an energy content of 11.1 kWh and weigh only 8.4 kg. To deliver the same amount of energy, approximately 280 kg of lead-gel batteries would be required.
EFOY fuel cartridges have been designed to meet the strictest safety standards and have received UN approval for transportation by sea, road, and air. Their design ensures that users are not exposed to the fuel at any time.
SFC Energy has established a global logistics network for the distribution of EFOY fuel cartridges. They are available through retailers worldwide and can be transported via road, sea, and air.
