  • Patent number: 11658317
    Abstract: The invention provides a method of inspection for erroneous assembly of a fuel cell stack which allows for determination of whether the fuel cell stack has been properly assembled without depending on the appearance of the fuel cell stack. The erroneous assembly inspection method inspects for erroneous assembly of a fuel cell stack that is produced by stacking power generation cells and dummy cells in proper power generation positions and proper dummy positions. The erroneous assembly inspection method measures a pressure difference in anode gas passages and cathode gas passages when gas is supplied at different pressures respectively to an anode gas inlet and a cathode gas inlet of the workpiece to determine whether or not the workpiece is in a third erroneous assembly state including a first abnormal cell in which a dummy MEA and a power generation separator are assembled.

  • Patent number: 11652240
    Abstract: Provided are new solid-state electrochemical cells and methods for fabricating these cells. In some examples, a solid-state electrochemical cell is assembled using a negative electrode, a positive electrode, and a gel-polymer electrolyte layer, which is disposed and provides ionic communications between these electrodes. Prior to this assembly, the negative electrode is free from electrolytes. The negative electrode is fabricated using a coating technique, e.g., forming a slurry, comprising a polymer binder and one or more negative active materials structures, such as silicon, graphite, and the like. The porosity, size, and other characteristics of the negative active materials structures and of the resulting coated later are specifically controlled to ensure operation with the gel-polymer electrolyte layer or, more specifically, high-rate charge and discharge, e.g., greater than 1 mA/cm2.

  • Patent number: 11652259
    Abstract: Provided is a method with which a separator-integrated electrode having a shutdown function can be easily produced using a water-insoluble polymer. The method for producing a separator-integrated electrode disclosed here includes the steps of: preparing a coating liquid in which a water-insoluble polymer is dissolved in a mixed solvent containing a good solvent for the water-insoluble polymer and a poor solvent for the water-insoluble polymer and in which polyethylene particles are dispersed; coating the coating liquid on an electrode; and vaporizing and removing the mixed solvent from the coating liquid coated on the electrode. A boiling point of the poor solvent is higher than a boiling point of the good solvent. A porous separator layer is formed by removing the mixed solvent through vaporization and thereby forming pores.
