SUPPLY METHOD OF LIQUEFIED PETROLEUM GAS TO HYDROGEN MANUFACTURING SYSTEM FOR FUEL CELL, HYDROGEN MANUFACTURING SYSTEM FOR FUEL CELL WITH SAME SUPPLY METHOD INCORPORATED, AND FUEL CELL SYSTEM

摘要

PPROBLEM TO BE SOLVED: To provide a fuel cell system, and an excellent hydrogen manufacturing system for a fuel cell with the hydrogen manufacturing system incorporated for stably obtaining hydrogen gas by continuously supplying the liquefied petroleum gas with a stable composition reduced in sulfur content. PSOLUTION: A supply method of the liquefied petroleum gas for supplying continuously to the hydrogen manufacturing system for the fuel cell supplies the fuel gas from a supply side container 1 for housing raw liquefied petroleum gas and a supply side container 1 of a preliminary side container 2 which are combined to use through a sulfur detector 3 to a desulfurizer 4, reformer 5, and fuel cell stack 6, switches the supply of the fuel gas from the supply side container 1 to supply from the preliminary side container 2 by an automatic control valve 7 when a sulfur contained concentration of the supply fuel gas measured by the detector 3 reaches a predetermined set concentration, and continuously supplies to the hydrogen manufacturing system for the fuel cell.
