Title: FUEL SUPPLY SYSTEM, FUEL CELL SYSTEM, AND METHOD FOR RUNNING EACH
Abstract:
In the present invention, gaseous fuel is stably supplied with the amount of heat generation as the control value even if the composition of the gaseous fuel changes. A composition-independent flow rate meter (4) that can measure flow rate independently of the composition of the gaseous fuel is disposed in series with a thermal flow rate meter (3) in the supply pathway of gaseous fuel. When the value measured by the thermal flow rate meter (3) and the value measured by the composition-independent flow rate meter (4) diverge by at least a certain amount, it is determined that there is an abnormal state, and a conversion factor is set with respect to the value measured by the thermal flow rate meter (3). On the basis of the conversion factor, the composition of the gaseous fuel is inferred, on the basis of which the amount of heat generation of the gaseous fuel is inferred. On the basis of the amount of heat generation of the gaseous fuel, the amount of supply of the gaseous fuel by a fuel supply device (2) is adjusted in a manner so that a target amount of supply heat generation per unit time is obtained.
