It is shown that a material sintered from fine-grained nickel powder is promising for the manufacture of anodes of high-temperature fuel cells. On the basis of experimental data of strength of nickel anode material the technological mode of its processing is optimized. The duration of the oxidation stage was determined to be 90 minutes. as the best to ensure stable conditions of redox treatment of this material.
At the oxidation stage, an increase in the strength of the material was achieved (the average level is 36.3 MPa) for its duration of 90 minutes. The inexpediency of its further oxidation due to the appearance of a stress gradient and the formation of microcracks, which reduces the strength of the material and leads to the loss of structural integrity of the anode, is substantiated.
