ABSTRACT:
A system and method for removal or oxidative decomposition of fuel from a fuel storage container for use in a direct oxidation fuel cell and direct oxidation fuel cell system wherein the fuel permeates through a material and can be exposed to a catalyst/enzyme which oxidizes the fuel as it leaves the storage container. The system includes a fuel storage container provided with a catalyst-coated material. An airtight seal is provided over the catalyzed area, which seal is broken to allow oxygen access, and consequently the catalytic reaction. The airtight seal may be broken by simple manual methods or automatic methods on removal of the container from the fuel cell system.
