Abstract
A fuel battery cell comprising a battery structureand a support plate, the battery structurehaving a power generation region G of a lamination of an anode electrode layer, an electrolyte layer, and a cathode electrode layer, and the support platebeing made of metal, being disposed on the anode electrode layerside of the battery structure, in which the support plateintegrally includes a main body partA and a frame partB, the main body partA having gas permeability, the frame partB having gas impermeability and having small thickness, the support plateB has a step surfaceD between the main body partA and the frame partB, on the surface on the anode electrode layerside, and the electrolyte layeris disposed in a way it extends to the step surfaceD and the frame partB, is provided. A risk of application of a tensile load to the electrolyte layeris removed, when the support platethermally expands during power generation, whereby a good gas barrier property at an end part of the battery structureis maintained.
