Abstract
A method for bonding a solid electrolyte layer and electrodes used a fuel cell includes: laminating the solid electrolyte layer and the electrodes so that the electrodes sandwich the solid electrolyte layer therebetween; applying a first voltage of a first polarity between the electrodes sandwiching the solid electrolyte layer; and applying a second voltage of a second polarity that is the reverse of the first polarity between the electrodes sandwiching the solid electrolyte layer.
Claims27
A method for bonding a solid electrolyte layer, a cathode and an anode for a fuel cell, comprising:
- laminating the solid electrolyte layer, the cathode and the anode so that the cathode and the anode sandwich the solid electrolyte layer therebetween;
- covalent bonding at an interface between the solid electrolyte layer and one of the cathode and the anode by applying a first DC voltage of a first polarity between the cathode and the anode sandwiching the solid electrolyte layer;
- and
- covalent bonding at an interface between the solid electrolyte layer and the other one of the cathode and the anode by applying a second DC voltage of a second polarity that is the reverse of the first polarity between the cathode and the anode sandwiching the solid electrolyte layer after completion of the covalent bonding between the solid electrolyte layer and the one of the cathode and the anode.
