ABSTRACT:
A cell plate structure for a fuel cell is provided with a porous substrate, a lower electrode layer formed on the porous substrate, an upper electrode layer opposed to the lower electrode layer, a solid electrolyte layer having a layer element placed between the lower electrode layer and the upper electrode layer and composed of a plurality of divided electrolyte regions, a gas impermeable layer correspondingly covering an area where the solid electrolyte layer is absent on the porous substrate or on the lower electrode layer. The gas impermeable layer separates gas passing inside the porous substrate and gas passing outside the porous substrate. Such a cell plate structure is suited for use in a solid electrolyte type fuel cell.
