Abstract
A replenisher is used in a system to replenish a fuel cell. The replenisher has a casing that extends around an interior space. The casing has a partition that defines an infeed chamber and an outfeed chamber within the interior space. The partition has an access channel that extends between the infeed and outfeed chambers. The chambers each have a port. The replenisher has a biaser disposed within the casing. The biaser pressurizes the infeed chamber positively and the outfeed chamber negatively.
