Abstract:
1. A fuel cell stack comprising: a housing; a stacked series of fuel cells located in the housing, each cell having an inlet end for receiving a reactant gas; a manifold located in the housing and communicating a feed stream from a source to each of the inlet ends of the fuel cell; a water spray mechanism located in the manifold and producing nebulized water in the feed stream; and a filter packing defining an evaporative element interposed between the manifold and the inlet ends of the fuel cell and receiving a portion of the nebulized water, the filter packing inhibiting the nebulized water from entering the inlet ends of the fuel cell and promoting evaporation of the received nebulized water into the feed stream as the feed stream passes through the filter packing and into the inlet ends of the fuel cell.
