Document Type and Number:
Japanese Patent JP2023121039
Kind Code:
A
Abstract:
To suppress water adsorption of a desulfurization agent that desulfurizes a material gas supplied to a fuel cell.SOLUTION: A fuel cell system 10 comprises: an FC (fuel cell) stack 42 that generates power with a fuel gas supplied to an anode 42A and air supplied to a cathode 42B; a desulfurizer 12 provided at an upstream side from the anode 42A to remove a sulfur component from gas supplied from a gas piping 41; a dew point meter 11 provided at an upstream side from the desulfurizer 12 to measure a dew point of gas flowing through the gas piping 41; and a gas supply control unit 48 that stops gas supply from piping 4 to the desulfurizer 12 when the dew point measured by the dew point meter 11 becomes larger than a threshold TH1.SELECTED DRAWING: Figure 3
