摘要： Improved methods are disclosed for shutting down and storing a fuel cell system, particularly for below freezing temperature conditions. The methods comprise stopping power production from the fuel cell stack, monitoring its temperature, and repeatedly performing a predetermined warming operation if the stack temperature falls to a normal threshold temperature. In the improved methods, either an initial threshold temperature and/or an initial warming operation are used that differ from the respective normal threshold temperature and the predetermined warming operation.

摘要： [Problem] To provide a fuel-cell-stack manufacturing method capable of increasing the load that a raised piece of a deformation absorption member can receive from the separator unit. [Solution] The deformation absorption member 20 used in the fuel-cell-stack 1 manufacturing method is disposed between an anode side separator 11 and a cathode side separator 12, and comprises a thin-board-like base material 21, and a plurality of raised pieces 22 that are provided raised from one surface 21a of the base material in a grid pattern. In the arrangement step, an extension portion (the free end portion 22b) extended from the proximal end (the fixed end portion 22a) of the raised piece provided on one surface of the base material is disposed so as to be abutted to the cathode side separator or the anode side separator. The setting step sets the interval between the anode side separator and the cathode side separator along the lamination direction X so that the deformation of the raised piece exceeds an elastic deformation region and enters a plastic deformation region, and is also in a region in which the proximal end that is moved due to the deformation will not come in contact with the cathode side separator or the anode side separator.

摘要： A cell (2) of a fuel cell includes a membrane electrode assembly (3), and metal first (7A) and second (7C) separators which sandwich the membrane electrode assembly to form gas flow paths (8A, 8C) disposed on each side of the membrane electrode assembly. A back surface (26) of the first separator and a back surface (26) of the second separator, the first separator and the second separator being included in adjacent cells, are in contact with each other, thereby forming a temperature-control medium flow path (9) between the first separator and the second separator. In the first separator and the second separator, corrosion-resistant coating layers (27) are provided only on reaction-side surfaces (25) of the first separator and the second separator, the reaction-side surfaces facing the membrane electrode assembly, and portions where the back surface of the first separator is in contact with the back surface of the second separator are joined by welded portions (10).

摘要： A control method for a fuel cell system that includes a solid oxide fuel cell configured to generate power upon receipt of supply of an anode gas and a cathode gas includes an anode protection execution determination process of performing execution determination of an anode protection process of applying a predetermined protection current to the fuel cell in order to restrain catalyst oxidation in an anode of the fuel cell. In the anode protection execution determination process, an internal impedance of the fuel cell at an anode response frequency at which an anode reaction resistance of the fuel cell is detectable is acquired, and based on the internal impedance at the anode response frequency, whether the anode protection process is to be executed or not is determined.
