Stabilization of a Numerical Model Through the Boundary Conditions for the Real-Time Simulation of Fuel Cells

The fuel cells are to convert chemical energy directly to electricity with high efficiency. From an environmental point of view, it is worth emphasizing that the fuel cells are not emitting any greenhouse gases or other pollutants. To increase the efficiency of the fuel cells their properties must be analyzed deeply. To this aim numerical modeling is a very useful tool. The fuel cell system models are usually solved by applying constant currents with long time step. For our purposes high amplitude sine perturbation and real-time simulation are needed, because during the control of a fuel cell the information needs to be available in real-time. In this article our method for approaching the real time simulation is formulated including the so-called scaling method. Using this method, the real-time simulation of fuel cells is getting easier and more accurate.
