FUEL CELL SYSTEMS WITH WATER RECOVERY FROM FUEL CELL EFFLUENT

Fuel cell systems that use a desiccant to recover water from fuel cell effluent. In some embodiments, the fuel cell system may include one or more fuel cells configured to generate electrical output from a supplied fuel and an oxidant while emitting effluent. The fuel cell system also may include a desiccant disposed downstream of the one or more fuel cells. The desiccant may bind water from at least a portion of the effluent. Heat then may be generated to release bound water from the desiccant. The heat may be generated by combustion of an exhausted fuel from the fuel cells and/or by combustion catalyzed by a combustion catalyst disposed downstream of the fuel cells.
