Title:
燃料電池発電システム
Document Type and Number:
Japanese Patent JP7181060
Kind Code:
B2
Abstract:
To provide a fuel cell power generation system, effectively using at least one of cold heat of low-temperature liquid fuel and expansion energy generated when the low-temperature liquid fuel vaporizes.SOLUTION: A fuel cell power generation system 10A includes: an oxide gas pipe P1 through which low-temperature liquid fuel at a temperature of 0°C or below is supplied; a first fuel battery cell stack 12 and a second fuel battery cell stack 14 which generate electricity using fuel gas obtained by vaporizing the low-temperature liquid fuel and oxidant gas containing oxygen and which discharge off gas containing first carbon dioxide gas; and a carbon dioxide gas liquefaction part 24 for liquefying the carbon dioxide gas by compression cooling using cold heat and expansion energy of the low-temperature liquid fuel.SELECTED DRAWING: Figure 1
