Abstract

There is provided a polymer electrolyte fuel cell cartridge for supplying a fuel and an oxidizer to a polymer electrolyte fuel cell, including at least two chambers in which: one chamber stores the fuel; and the other chamber stores the oxidizer. The fuel includes one of hydrogen and an aqueous methanol solution, and the oxidizer includes at least one of oxygen, air, ozone, and hydrogen peroxide. There is provided a polymer electrolyte fuel cell including the polymer electrolyte fuel cell cartridge connected thereto, to thereby provide more stable power output.

Claims

1. A polymer electrolyte fuel cell cartridge for supplying a fuel and an oxidizer to a polymer electrolyte fuel cell, comprising at least two chambers wherein:

one chamber stores the fuel; and

the other chamber stores the oxidizer.

2. The polymer electrolyte fuel cell cartridge according to claim 1, wherein:

the fuel comprises one of hydrogen and an aqueous methanol solution; and

the oxidizer comprises at least one of oxygen, air, ozone, and hydrogen peroxide.

3. The polymer electrolyte fuel cell cartridge according to claim 1, wherein at least one of the two chambers further stores an inert gas.

4. A polymer electrolyte fuel cell, comprising a polymer electrolyte fuel cell cartridge connected thereto for supplying a fuel and an oxidizer to the polymer electrolyte fuel cell, wherein:

the cartridge comprises at least two chambers;

one chamber stores the fuel; and

the other chamber stores the oxidizer.
