ABSTRACT:
A method of and fuel cell system for limiting an amount of a fuel crossing over a membrane in a fuel cell, the method including determining an appropriate molecular ratio of the fuel and water for a fuel-water mixture503; and controlling an amount of the fuel-water mixture that is available to an anode side of the membrane507in the fuel cell according to an amount of the fuel that will be electro-oxidized by the fuel cell. The fuel cell system includes a fuel cell membrane103having an anode layer107, a cathode layer109, and an electrolyte layer111where the cathode layer is exposed to an oxygen source, and a fuel delivery system105including a fuel chamber119disposed around and proximate to the anode layer at a side opposite to the electrolyte layer, the fuel delivery system implementing the method above.
