Modelling degradation phenomena in PEM fuel cells using Comsol Multiphysics

J. Ohs
R&D, Robert Bosch GmbH

Jan Ohs graduated in mechanical engineering at RWTH Aachen, Germany. In 2006/07, he studied at Imperial College London at the Department of Chemical Engineering and had first contact to fuel cells. Since 2008, he has been working in the R&D-department at Bosch in Stuttgart. He is using Comsol for modelling work on fuel cells for automotive application. The main focus is cell degradation.

According to the Gouy-Chapman theory, a double layer structure appears on the surface of a solid particle, a gas bubble, a liquid droplet, or a porous body when it is placed into a liquid. In this work, a one-dimensional model of the electrochemical reactions has been developed in the COMSOL Multiphysics environment. The model accounts for solution chemistry, cell potential, and solves the ...
