Simulation of Electromagnetically and Thermally Controlled Ionic Flow in a Fuel Cell
A major issue related to the use of fuel cells to convert electrical energy in chemical energy in modern power supply concepts are their bad dynamical properties. To overcome these problems, it seems promising to introduce a suitable mechanism to control the ionic flow inside the fuel cell. The purpose of this work is to estimate the potential of certain approaches to controlling the ionic flow inside the fuel cell via magnetic and temperature fields. To this end, mathematical models combining a description of the ionic movement in a hydrogen fuel cell with a model for the effects of an additional magnetic or temperature field, respectively, are proposed. Further the implementation of these models in the context of the finite element method combined with other simulation techniques is discussed, such as, e.g., a molecular dynamic model. Finally, some preliminary results are presented.
