Abstract:
1. A fuel cell system for use in controlling the amount of oxygen or air migrating to a fuel cell anode, the fuel cell anode having an input and an output, the system including a gaseous composition of at least one of hydrogen, an anhydrous anode gas mixture from the anode output, or a blend thereof, the system comprising: a primary hydrogen source capable of providing hydrogen to the input to the fuel cell anode; a secondary hydrogen source having an input and an output, the secondary hydrogen source being situated between the primary hydrogen source and the fuel cell anode, the secondary hydrogen source being capable of selectably receiving hydrogen; and a first valve downstream of the secondary hydrogen source output and communicating with the primary hydrogen source, the valve being capable of directing the hydrogen from the secondary hydrogen source to either the fuel cell anode input or the gaseous composition and subsequently to the fuel cell anode input.
