A fuel reformer burner in which fuel gas and anode-off-gas (AOG) may be burned and backfire may be prevented during combustion of AOG includes a fuel supply portion, an anode-off-gas (AOG) supply portion; and a combustion air supply portion. The fuel supply portion and the AOG supply portion are arranged inside the combustion air supply portion, which is formed to extend beyond the discharge sides of the fuel supply portion and the AOG supply portion.

Fuel reformer burner of fuel cell system

A stable fuel supply system in a fuel cell system produces heat and electricity by combining hydrogen modified from a major raw material selected from various hydrogen compounds, with oxygen existing in air. A fuel supply device and a fuel supply method in a fuel cell system, which automate a steam to carbon ratio (S/C) control and a lamda control, and achieve a fuel cell system operation efficiently and stably coping with pressure loss and pulsation occurring within the system, while using a minimum number of balance-of-plant (BOP) units. A method more efficiently and precisely supplies fuel during the start-up and operation of the fuel cell system, while preventing flame failure of a burner and maintaining an appropriate carbon monoxide concentration even when an abrupt flow rate variation occurs. Also, an operating method improves functions associated with a decomposition ability based on selection of the specification of a fuel pump, and thus, is more economical and stable in terms of the costs and configuration of the fuel cell system.
