The fuel cell stack of our EFOY and EFOY Pro Fuel Cells is fuelled by
methanol. Inside the stack, hydrogen is extracted from the injected
methanol as part of an electrochemical reaction (direct methanol fuel
cell technology). Pure methanol is supplied in SFC’s patented fuel
cartridges specifically design for use with our EFOY and EFOY Pro Fuel
Cells. Use only EFOY methanol cartridges for maximum lifetime.
