Even longer autarky with hybrid solution
Autonomous power with EFOY fuel cartridges
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.
The highest quality standards
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.
EFOY Energy Calculator
