Abstract

Abstract : 3D multiphysics modelling of fuel cell components and fuel cell systems has been a core research field since many years. Current focus has been to support the commercialisation of the technology. Especially, gaining detailed information about the durability and life duration of the utilised fuel cell systems is of paramount importance. As a fuel cell system consists of many components like the fuel cell stack, reformer, afterburner, heat exchanger etc., it is important to account for the coupled processes, occurring within each component and their interaction with the neighbour components. To interpret the long-term reliability of the system, the thermomechanical fatigue behaviour of the critical system regions have been investigated in detail to predict and understand the durability under cyclic load. The life expectation of a system has been predicted using a 3D full scale system level multiphysics model based on coupled CFD-FEM.
