Outline of Final Research Achievements

We have developed High Functional-Direct Carbon Fuel Cell (HF-DCFC) composed of the molten salts gasification system and Tubular-MCFC which is replaced with the gas supplying tube of the gasification system. We obtained the following knowledge as a result of a variety of examining for constructing of HF-DCFC. (1) Li/K system carbonate was suitable for HF-DCFC. (2) Although we began to make T-MCFC by trial and error, we finally were able to establish the manufacturing method of T-MCFC. (3) We obtained the cell voltage of 600mV @100mA/cm2 as the performance of T-MCFC by reducing contact resistances of electric current terminals and by improving the resistance polarization of T-MCFC. (4) The cell performance was not able to be obtained as HF-DCFC by not generating gasified gas enough because the molten salts temperature became low with 700°C to keep 650°C the temperature of MCFC.
