LONG MONOLITHIC PLANAR CELL: A NEW SOFC DESIGN FOR HIGH POWER DENSITY GENERATION

摘要

A new type solid oxide fuel cell has been designed and developed Tor high power density generation. The single cell has a long monolithic planar structure consisting of an anode, an electrolyte, a cathode and an interconnection. The planar structure permits a low internal cell resistance. The monolithic self-sealing structure enables easy gas-sealing and cell-stacking. The long structure has mechanical stability under the large temperature differences in the cell. These advantages show that a solid oxide fuel cell of improved reliability and power density can now be provided. A power density of 0.48 W/cm~2 was obtained in a small single cell test at 1000℃ using wet hydrogen and oxygen.
