摘要： A cell unit is provided for a solid oxide fuel cell, and has a sequential stack of a power generation cell, an auxiliary collector layer and a separator. The power generation cell includes a cathode layer, an electrolyte layer, and an anode layer. The auxiliary collector layer assists electrical contact. The separator is provided with flow passage portions that define a gas flow passage for gas. The auxiliary collector layer has a curved in an arch shape that is disposed so as to overlap the gas flow passage in the stacking direction, and that is curved so as to project toward the power generation cell side.

摘要： A fuel battery cell comprising a battery structure 1 and a support plate 2, the battery structure 1 having a power generation region G of a lamination of an anode electrode layer 4, an electrolyte layer 5, and a cathode electrode layer 6, and the support plate 2 being made of metal, being disposed on the anode electrode layer 4 side of the battery structure 1, in which the support plate 2 integrally includes a main body part 2A and a frame part 2B, the main body part 2A having gas permeability, the frame part 2B having gas impermeability and having small thickness, the support plate 2B has a step surface 2D between the main body part 2A and the frame part 2B, on the surface on the anode electrode layer 4 side, and the electrolyte layer 5 is disposed in a way it extends to the step surface 2D and the frame part 2B, is provided. A risk of application of a tensile load to the electrolyte layer 5 is removed, when the support plate 2 thermally expands during power generation, whereby a good gas barrier property at an end part of the battery structure 1 is maintained.

摘要： A fuel cell stack FS includes: a stack A that includes a single cells C that are stacked, each of the single cells including a frame 2 that holds an outer periphery of a membrane electrode assembly 1 and a pair of separators 3, 4 sandwiching the membrane electrode assembly 1 and the frame 2; and a case 50 that houses the stack A. The frame 2 comprises a protrusion 11 that protrudes outward from an outer periphery of a frame body 2A beyond an outer peripheral edge of the pair of separators 3, 4. A protrusion length of the protrusion 11 is greater than at least a gap between the frame 2 and one of the pair of separators 3, 4, and the protrusion 11 is bendable with respect to the frame body 2A. The protrusions prevent a contact between the separators 3, 4 of the single cell C and a contact between the end faces of the separators 3, 4 and the case 50 so as to prevent a short circuit of the single cell C.

摘要： A single fuel cell, a plurality of which are to be stacked to form a fuel cell stack, includes a membrane electrode assembly having a structure including paired electrode layers and an electrolyte membrane held between the paired electrode layers, paired separators each forming a gas passage between the separator and the membrane electrode assembly, and a displacement absorber having a conductive property and interposed between one separator of the single fuel cell and an adjacent-side separator of another single fuel cell to be stacked adjacent to the single fuel cell. The displacement absorber is connected to at least any one of the separators.
