Research of sets of solid oxide fuel cells in packed version

The stressed state of fuel cells in a package is considered. It was found that for αi=1.2×10-5k-1, the rational geometric characteristic for a planar SOFC in a batch design is γi=6×10-2. It is concluded that if the relative thickness of the edge element of the SOFC stack is of planar design γi>6×10-2, then the resulting deformation complication will be characterized by the loss of stability of the structure. Otherwise, i. e. at γi-2, stacked SOFC elements can lose stability until plasticity appears in their materials. Consequently, only at γi=6×10-2, the use of the potentials of structures can be achieved both in terms of the stability of its elements and the strength of their materials.
