ELECTRODE FOR MOLTEN CARBONATE FUEL CELL AND ANODE ELECTRODE OPTIMIZING METHOD FOR OPTIMIZING ANODE ELECTRODE

摘要

PPROBLEM TO BE SOLVED: To make stability excellent for a long period by restraining lowering of voltage even if such a fuel of high CO concentration such as coal gasified gas, waste gasified gas or biomass gasified gas. PSOLUTION: On the electrode for the molten carbonate fuel cell using fuel reformed gas with an HSB2/SB/CO concentration ratio of 1.2 or less, the cathode is made of NiO. Provided that a diameter of a cathode central pore dc ranges from 4 to 10 m, a diameter of an anode central pore da is within a range of da=0.497cd+0.120.5 [m]. PCOPYRIGHT: (C)2006,JPO&NCIPI
