All SFC fuel cells are direct methanol fuel cells (DMFC): On the anode side, a methanol-water mixture is supplied to the cell by the internal fluid management. One of SFC's unique capabilities is the use of neat (100%) methanol as the fuel in the cartridge. The cathode side is supplied with air. Both, the anode and the cathode are connected through an electric circuit. In contact with the platinum catalyst methanol is converted into carbon dioxide (waste gas), protons and electrons. The electrons circulate from the anode side to the cathode via the electric circuit, while the protons pass through the membrane which divides the cell. On the cathode side, the protons, electrons, and the oxygen react to form pure water. |

| Due to the heating of the fuel cell while operating the evolving water is emitted as water vapor. Another by-product is a small amount of carbon dioxide. The overall amount of by-products equals the respiratory exhalation of a small child while playing. |
