PROBLEM TO BE SOLVED: To provide a system and a method for supplying fuel gas for a fuel cell, capable of achieving a stable operation of a fuel cell system by grasping the gas composition of inlet fuel gas.SOLUTION: A fuel gas supply system for a fuel cell includes: a fuel supply line Lsupplying fuel gas 11; an oxidant supply line Lsupplying an oxidant (air) 12; a fuel cell 13 generating power by the fuel gas and the oxidant that are supplied; and a first laser fuel composition measuring device 21A measuring the composition of the fuel gas 11. Hydrogen equivalent is obtained from the fuel gas composition measured using the first laser fuel composition measuring device 21A. |
