Abstract
A passive water drain for removal of water from a fuel cell system is disclosed, the drain including a main body having a cavity formed therein, an interior element, and a hydrophilic porous media. The passive water drain is adapted to simplify the anode reactant recycler, eliminate the need for bypass valve systems used to remove water from the cathode exhaust, and eliminate the need for condensate draining systems used for compressed air entering the cathode.
