A hydrogen storage system and method having a main hydrogen storage site
that contains a sufficient amount of hydrogen for a fuel cell employing a
polymer membrane to generate power in accordance with a predetermined
electrical power requirement. A main storage site is provided to store
and supply hydrogen to meet the electrical power requirement for the fuel
cell. An auxiliary hydrogen storage site contains a sufficient amount of
hydrogen to allow the fuel cell to operate on a scheduled basis that is
required to maintain the polymer membrane hydrated. A manifold connects
the main and auxiliary hydrogen storage sites and has an outlet to
deliver hydrogen to the fuel cell. The manifold allows the auxiliary
hydrogen storage site to be renewed independently of the main storage
site and has a flow control network to allow the fuel cell to draw
hydrogen from the auxiliary hydrogen storage site for maintenance
purposes without utilization of the hydrogen from the main hydrogen
storage site.
