Molten carbonate fuel cell power generation system. Yoyu tansan prime en gata nenryo denchi hatsuden sochi

Abstract

In an indirect internal reforming type molten carbonate fuel cell, the reforming temperature is limited less than the operating temperature of the fuel cell, as the heat source for reforming is depended on the reaction heat at about 650 {degree} C of the fuel cell. To improve the reforming rate at the low temperature range, it is considered to increase S/C (ratio of steam to carbon), but this scheme will cause such problems as to increase the voltage drop of the anode, to drop the heat recovery ratio on the cogenerator, to increase the capacity of the heat exchanger, etc. In this invention, in the power generating plant of a molten carbonate fuel cell the inert gas is added to the reforming raw gas, and in addition to the above the gas is mixed with steam and led into the reforming chamber of the plant. When the inert gas which is not directly concerned in the reforming reaction is added to, total mol number increases and the reforming reaction is acceralated. Consequently, the reforming rate can be raised, though the reforming temperature is low. 2 figs.
