摘要： 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.
