| Research Abstract |
SOFCs are the most flexible fuel cells, and internal reforming and/or simple external reforming may be possible. In this study, the multi-fuel capability of SOFCs is considered from both thermodynamic and kinetic viewpoints. Equilibria in various possible SOFC fuel gases are examined. Power generation characteristics for various types of fuels are then measured and compared with those for simulated reformed gas in equilibrium compositions. We have succeeded to demonstrate direct-alcohol SOFCs for e.g. methanol and ethanol. Higher hydrocarbons including iso-octane (C_8H_<18>), n-decane (C_<10>H_<22>), and n-dodecane (C_<12>H_<26>) are highlighted as simulated gasoline and kerosene. Mixtures of CH_4 and CO_2 are used as simulated biogas, the use of which may enable us to realize a carbon-neutral zero-emission energy system with SOFC technology. Influence of fuel impurities on power generation characteristics is also examined and discussed.
