    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 mixture (503); and controlling an amount of the fuel-water mixture that is available to an anode side of the membrane (507) in 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 membrane (103) having an anode layer (107), a cathode layer (109), and an electrolyte layer (111) where the cathode layer is exposed to an oxygen source, and a fuel delivery system (105) including a fuel chamber (119) disposed around and proximate to the anode layer at a side opposite to the electrolyte layer, the fuel delivery system implementing the method above.
