POWER GENERATION SYSTEMS AND METHODS UTILIZING CASCADED FUEL CELLS

摘要

A power generation system 100 including a first fuel cell 200 configured to generate a first anode tail gas stream 22 is presented. The system 100 includes at least one fuel reformer 300 configured to receive the first anode tail gas stream 22, mix the first anode tail gas stream 22 with a reformer fuel stream 12 to form a reformed stream 30; a splitting mechanism 400 to split the reformed stream 30 into a first portion and a second portion; and a fuel path configured to circulate the first portion to an anode inlet of the first fuel cell 200, such that the first fuel cell 200 is configured to generate a first electric power, at least in part, by using the first portion as a fuel. The system 100 includes a second fuel cell 500 configured to receive the second portion, and to generate a second electric power, at least in part, by using the second portion as a fuel.
