| Outline of Final Research Achievements |
In this research, to establish measures against carbon deposition and sulfur poisoning, which is a problem of gasoline power generation solid oxide fuel cells (SOFCs), we performed a systematic experimental study using octane as a fuel and clarified the influences of the internal reforming method of fuel and reforming condition. We also clarified the influence of the carbon chain structure of the fuel and searched for a new anode material.
We clarified that it is impossible to suppress complete carbon deposition on the conventional Ni-YSZ anode, but we found also that it is possible to operate the SOFCs with our newly invented functional separation anode (Ni-YSZ/Ni/Ni-CeO2) without coking by the steam reforming under the conditions of steam/carbon ratio = 1 (mol) at 950°C. For the sulfur poisoning that is a concern in the Ni-based anode, we devised a new performance recovery method temporarily shifting the anode potential to the reduction potential and demonstrated the effect.
