EFOY Pro fuel cells are direct methanol fuel cells that are operated with the fuel methanol. The methanol is stored in EFOY fuel cartridges that have been designed especially for this purpose. Depending on requirements, EFOY fuel cartridges are available in 5, 10, 28 and 60 litre capacities. If your autonomy needs are higher, two fuel cartridges can be connected to up to four fuel cells using the DuoCartSwitch. This means you can autonomously run a 25 W application with four M28 fuel cartridges for up to 30 weeks for example.
Ultra-pure and clean methanol is required for the reliable operation of EFOY Pro fuel cells. To ensure compliance with the strictest safety standards, each filling operation is supervised by SFC quality management. Only when original EFOY fuel cartridges are used, can the maximum operating life of the fuel cell be guaranteed. The high energy density of methanol provides a lot of energy in a very small space with EFOY fuel cartridges. As a result, the autonomy of your off-grid application can be increased many times.

10 litres of methanol has a capacity of 11.1 kWh of energy and weighs just 8.4 kg. To deliver the same quantity of energy, around 280 kg of lead-gel batteries would be needed.
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 the user is never at risk of coming into contact with their contents.
SFC has established a global logistics network for the sale of EFOY fuel cartridges. EFOY fuel cartridges are available from SFC retailers worldwide. EFOY fuel cartridges can also be transported on pallets via road, sea and air.
