Summary

The current status of two types of SOFC R & D at TOTO is summarized. We have developed 10kw class tubular SOFC modules for stationary power generation using Japanese town gas (13A) as fuel. A small module which consisted of 5 stacks (a stack consisted of 2 × 6 cells) generated 1.5kW at 0.2A/cm2 and achieved 55%-LHV efficiency at an average temperature of 900°C. A thermally self-sustaining module consisting of 20 stacks achieved 6.5kW at 0.2A/cm2 and 50%-LHV.

We have also developed micro tubular SOFCs for portable application, which operate at relatively lower temperatures. The single cell generated 0.85, 0.70, and 0.24W/cm2 at 700°C, 600°C, and 500°C, respectively demonstrated 43W, 37W and 28W at a temperature of 700°C, and 500°C, respectively.
