Definitions

  • the invention relates to fuel storage containers for fuel cells, such as direct methanol fuel cells, generally having replaceable flexible inner containers.
  • the invention relates to fuel storage containers suitable for use with portable fuel cell applications.
  • a fuel cell is an electrochemical device that can convent energy stored in fuels such as hydrogen, oxygen, methanol and the like, into electricity without combustion of the fuel.
  • a fuel cell generally comprises a negative electrode, a positive electrode, and a separator within an appropriate container.
  • Fuel cells operate by utilizing chemical reactions that occur at each electrode. In general, electrons are generated at one electrode and flow through an external circuit to the other electrode where they are consumed. This flow of electrons creates an over-voltage between the two electrodes that can be used to drive useful work in the external circuit.
  • several “fuel cells” are usually arranged in series, or stacked, in order to create larger over-potentials.
  • a fuel cell is similar to a battery in that both generally have a positive electrode, a negative electrode and electrolytes.
  • a fuel cell is different from a battery in the sense that the fuel in a fuel cell can be replaced without disassembling the cell to keep the cell operating.
  • fuel cells have several advantages over other sources of power that make them attractive alternatives to traditional energy sources. Specifically, fuel cells are environmentally friendly, efficient and utilize convenient fuel sources, for example, hydrogen or methanol.
  • Fuel cells have potential uses in a number of commercial applications and industries. For example, fuel cells are being developed that can provide sufficient power to meet the energy demands of a single family home. In addition, prototype cars have been developed that run off of energy derived from fuel cells. Furthermore, fuel cells can be used to power portable electronic devices such as computers, phones, video projection equipment and the like. Fuel cells designed for use with portable electronic equipment provide an alternative to battery power with the ability to replace the fuel without replacing the whole cell. Additionally, fuel cells can have longer power cycles and no down time for recharging, which also makes fuel cells an attractive alternative to battery power for portable electronics. With the number or portable electronics currently being used for personal and business purposes throughout the world, various alternatives for powering the devices in specific applications would be desirable.
