Provided are: an anode for fuel cells, which is able to suppress interlayer separation between an active layer and a diffusion layer, and which is easily capable of achieving good gas diffusion properties and a good number of reaction sites; and a single cell of a fuel cell, which uses this anode for fuel cells. An anode (10) for fuel cells is used for a single cell (5) of a fuel cell, which comprises an anode (1), a solid electrolyte layer (2) and a cathode (3). The anode (10) for fuel cells is provided with: an active layer (11) that is arranged on the solid electrolyte layer (2) side and contains a small-diameter void (110); and a diffusion layer (12) that is laminated on a surface of the active layer (11), said surface being on the reverse side of the solid electrolyte layer (2)-side surface, and contains a large-diameter void (120). The active layer (11) has a plurality of active layer-side projections (111a). The diffusion layer (12) has a plurality of diffusion layer-side projections (121a). The anode (10) for fuel cells has a buffer region (13) that is configured to contain an active layer-side projection (111a) and a diffusion layer-side projection (121a) so that the active layer-side projection (111a) and the diffusion layer-side projection (121a) are in contact with each other. |
