First gas flow passage grooves which communicate with an oxygen-containing gas inlet, and second gas flow passage grooves into which the first gas flow passage grooves are merged and which communicate with an oxygen-containing gas outlet are provided on a surface of a first separator. First communication passages and second communication passages for enabling the air to flow therethrough are provided at first and second bent sections of the first gas flow passage grooves and the second gas flow passage grooves. Accordingly, when the air flowing in the surface of the separator is bent over, then the flow rate of the air is not partially lowered, and it is possible to reliably remove produced water.
