A fuel cell power generating apparatus (1) using a fuel cell stack (2) includes an air intake manifold (45) mounted above the stack for supplying air to a plurality of longitudinally extending air flow passages of fuel cells in stack; one or more of nozzles (55) mounted to side walls of THE air intake manifold for injecting water into the air intake manifold; and water supply system (50) for supplying water to the nozzles. In a preferable embodiment, the nozzles are mounted respectively to a pair of opposite side walls of the air intake manifold at location offset to each other or at different angle of water injection, to facilitate complete dispersion or distribution of water over the entirety of the air intake manifold, which allows smooth entry of the sprayed water to the respective air flow passages of the fuel cells.

[ What is claimed is:] [1.]1. A fuel cell system comprising:a stack of a plurality of fuel cells, each having an anode, a cathode and an electrolyte membrane interposed between said anode and said cathode;an air intake manifold defining an open chamber extending across and in direct communication with said stack;a plurality of air flow passages extending between upper open ends and lower open ends, said upper open ends opening directly into said open chamber of said air intake manifold for receiving air and for conveying the received air into contact with the cathodes of said fuel cells and then out of said stack; andwater supply means mounted in said open chamber of said air intake manifold for introducing liquid water droplets directly into said upper open ends of all of said air flow passages, whereby liquid water is carried into contact with said cathodes.
