After hydrogen fed from introduction hole 22 is dispersed in a first space 15 as a first buffer part, the hydrogen is further dispersed in a first recess part 28 and a second recess part 30 as a second buffer part, which is then uniformly dispersed in individual paths 26 between block groups 25 to make the volume of hydrogen flowing in the paths 26 uniform, and is then transferred at a sufficient feed pressure into small openings 24 through the second recess part 29 for uniformly feeding hydrogen to each cell unit.
