New honeycomb type SOFC for quick start operation
A honeycomb type SOFC using lanthanum gallate, scandium-stabilised zirconia as electrolyte for quick start operation within one minute, that has not been achieved ever, is under development.

Honeycomb cells will consist of fuel electrodes, air electrodes and air-cooling paths are arranged symmetrically with each other. Heat generated in the fuel electrodes is recovered by cooling air and delivered hot colling air is returned and induced into the air electrodes at the end of the honeycomb. Reformed fuel by the reformers inserted inside of the fuel cells is returned to the opposite end of the honeycomb and fed into the passage between the outer wall of reformers and inside wall of fuel electodes.
