In accordance with some embodiments of the present disclosure, a method of changing the porosity of the anode is presented. The anode is formed from a composition comprising nickel oxide, a doped ceria, and a stabilized zirconia wherein the weight percentage of the nickel oxide is greater than twenty-five percent. The anode may comprise a single or multiple layers, and may comprise at least one of gadolinia doped ceria (GDC), samaria doped ceria (SDC), or lanthania doped ceria (LDC); and at least one of Yttria stabilized zirconia (YSZ) or scandia stabilized zirconia (ScSZ). The anode may comprise multiple layers. Each layer may comprise a composition having the general formula NiO.sub.x-(doped ceria).sub.y wherein x and y are weight percentages of the composition, and wherein 25<x<100, and 25<y<100, and wherein each successive layer contains more nickel than the preceding layers.
