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 catalystenzyme which oxidizes the fuel as it leaves the storage container. In a region of a first conduction type of a semiconductor substrate, a first diffusion layer of a second conduction type opposite to the first conduction type is fabricated, the layer being connected to an inputoutput terminal. The system may be configured to check the ground taxi entries to ensure that each successive segment is contiguous with the last or next segment, and any gaps or discontinuities in the displayed taxi instructions may be annunciated.
