A fuel cell stack is a setup of a number of single fuel cells which have to be mechanically compressed each other to ensure good electrical conductivities and tightness against leakage of supplying gases (e.g. hydrogen) and cooling media.

In this study a 3D FEM model is developed with COMSOL Multiphysics® to analyze the mechanical design of a fuel cell stack. The material properties of the components are assumed to be independent of temperature. Thermal expansion of the components is considered by the implementation of temperature profile into the structural module. This analysis yields understanding the stack design in a mechanical point of view and assists with the optimization of the stack design and the dimensioning of the components.
