Metallic bipolar plates of the MCFC(Molten Carbonate Fuel Cell) are composed of one center plate and two shielded slot plates. The unit cell of the shielded slot plate is trapezoidal in shape. From the analytical analysis of the simplified model of the unit cell, the stiffness and strength of simple deformation are obtained. FEM simulations were conducted to verify the analytical result. The homogenized material model for a plastically compressible anisotropic core is employed to simulate the mechanical behavior of the unit cell. The coefficients of the orthotropic elasticity and the yield criterion are obtained from the FEM simulation of the unit cell. The comparisons of the mechanical behaviors are made between the unit cell and the homogenized model.
