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.
