Experimental Investigation of Contact Pressure Distribution in PEM Fuel Cells

This paper develops a PEMFC model to study the contact pressure distribution over the membrane electrode assembly using experimental setup and finite element method (FEM). Two-dimensional FEM model used to decrease the calculation time of the simulation. The simulation results have good agreement with experimental results obtained via pressure sensitive films. The experimental setup prepared for single cell and fifteen cells stack. Moreover, the effects of some parameters such as thickness of the end plates and position of the cell on the contact pressure distribution over the MEA were investigated. The results reveal that optimizing mentioned parameters leads to design PEMFCs with proper contact pressure distribution over the MEA.
