SULFIDE-BASED SOLID CELL MODULE

摘要

An object of the present invention is to provide a sulfide-based solid cell module which prevents a rapid deterioration in some unit cells caused by hydrogen sulfide. Disclosed is a sulfide-based solid cell module comprising a unit cell stack which comprises two or more stacked unit cells, wherein each of the unit cells comprises at least a positive electrode, an electrolyte layer and a negative electrode stacked in this order; at least one of the positive electrode, the electrolyte layer and the negative electrode comprises a sulfide-based solid material; and the two or more unit cells are stacked in a stacking direction of the positive electrode, electrolyte layer and negative electrode of each unit cell, and wherein a stacking direction of the unit cells of the unit cell stack is inclined at an angle of 45 to 90 degrees to the vertical direction.
