The invention relates to an anode for a high-temperature fuel cell having an anode substrate and/or a functional anode layer, comprising a porous ceramic structure having a first predominantly electron-conducting phase with the general empirical formula SrLnTiOwherein Ln=Y, Gd to Lu and 0.03&#x3c;x&#x3c;0.2, and having a second predominantly ion-conducting phase component comprising yttrium or scandium-stabilized zirconium dioxide (YSZ or ScSZ). In the anode substrate and/or the functional anode layer, the ratio by volume of the first phase to the second phase ranges from 80:20 to 50:50, and particularly from 70:30 to 60:40. The porosity of the entire anode ranges between 15 and 50% by volume. The anode additionally comprises a catalyst in the amount of no more than 15% of the total volume, which is disposed on the surface of the pores of the ceramic structure.
