燃料電池システム
Document Type and Number:
Japanese Patent JP7067496
Kind Code:
B2
Abstract:
To provide a fuel cell system including means for suppressing intake of metallic ions into a polymer electrolyte.SOLUTION: In a fuel cell including a cell stack laminating multiple single cells gripping a membrane electrode assembly by a stainless-steel separator, and a fuel cell system including a control section, the control section determines whether or not metal ion concentration in produced water drained from the fuel cell goes above a specified value, detects restraint pressure of the cell stack when the metal ion concentration goes above a specified value, and when the restraint pressure goes above a specified value, lowers the restraint pressure of the cell stack below a specified pressure.SELECTED DRAWING: Figure 3
