PROBLEM TO BE SOLVED: To provide a fuel battery that is able to improve uniformity of a reaction between a reaction fluid and an air electrode or a fuel electrode.SOLUTION: If unit areas SA1, SA2 or a unit width p, including both at least circulation parts 52, 54 and projecting parts 50, 51, is set for reaction regions 53, 55, the reaction regions 53, 55 have regions WA1, WA2, in which the proportions of the projecting parts 50, 51 per unit areas SA1, SA2 or unit width p is constant at each position in a planar direction. Thus, even if the arrangement patterns of the projecting parts 50, 51 differ according to positions in planar directions in the reaction regions 53, 55, the proportions of the areas occupied by the projecting parts 50, 51 can be made constant in each position in the planar directions of the reaction regions 53, 55. Accordingly, regardless of the positions of the reaction regions 53, 55 in the planar directions, the proportions of the areas of the circulation parts 52, 54, where a reaction fluid flows along a fuel electrode 13 or an air electrode 14, can also be made constant.SELECTED DRAWING: Figure 3 【課題】反応流体と空気極又は燃料極との反応の均一性を高めることができる燃料電池を提供する。【解決手段】反応領域５３，５５に対して、少なくとも流通部５２，５４及び突起部５０，５１の両方を含む単位面積ＳＡ１，ＳＡ２又は単位幅ｐを設定した場合、反応領域５３，５５は、単位面積ＳＡ１，ＳＡ２又は単位幅ｐ当たりに突起部５０，５１が占める割合が、平面方向における各位置において一定となる領域ＷＡ１，ＷＡ２を有している。これにより、突起部５０，５１の配列パターンが反応領域５３，５５内の平面方向における位置によって異なっていても、反応領域５３，５５の平面方向の各位置において、突起部５０，５１が占める面積割合を一定にすることができる。これにより、反応領域５３，５５の平面方向の位置によらず、燃料極１３又は空気極１４に沿って反応流体が流れる流通部５２，５４の面積割合も一定にすることができる。【選択図】図３
