A separator includes an imperforate separator substrate and spacer plates that are interposed between electrodes and the separator substrate. The spacer plates are formed of mesh and have rectangular wave-shaped cross-sections. Top portions of the rectangular waves that abut against the electrodes serve as gas diffusion portions. Adjacent side portions and portions between waves together are rectangular and serve as spacer portions which define gas passages between the gas diffusion portions and the separator substrate. Air holes that provide intercommunication between adjacent gas passages are provided in the spacer portions. As a result, gas can be supplied downstream of a gas passage that has become narrow or blocked due to a water droplet remaining in the passage.
