The stability of the Co8211;C and Pt8211;C eutectic fixed points is investigated in this article. Six cells were employed for the testing. Two existing cells, a Co8211;C cell with a C/C sheet incorporated and a Pt8211;C cell equipped with a graphite sleeve that had been previously aged, were studied to determine the presence of anomalous drifts or degrading robustness that may possibly appear when the testing period is extended. The stability of four cells of a new design, a Co8211;C cell and three Pt8211;C cells, which were constructed in a hybrid manner, to include a sleeve, foil lining, and two of them with a cavity support, were likewise tested. Results show that different designs of Pt8211;C cells can exhibit good stability. However, for Co8211;C cells, the cavity rift remains a problem. The possible reasons for this rift and methods for increasing cell life are discussed.
