Cell plate structure for solid electrolyte fuel cell, solid electrolyte fuel cell and related manufacturing method

摘要

A cell plate structure for a solid oxide electrolyte type fuel cell is provided with a lower electrode layer, an upper electrode layer provided in opposition to the lower electrode layer (5), a solid electrolyte layer (3) provided between the lower electrode layer and the upper electrode layer (4), and an area provided in at least one of the lower electrode layer and the upper electrode layer. The area has a portion which is formed by removing a substance, contained in the at least one of the lower electrode layer and the upper electrode layer during formation thereof, after the at least one of the lower electrode layer and the upper electrode layer has been formed. Such a fuel cell plate structure can be applied to a solid electrolyte fuel cell representatively by being disposed between a pair of separators that have gas flow passages supplying the lower electrode layer and the upper electrode layer with gasses, respectively.
