PEM automotive stack model with experimental validation

Dynamic models of PEM stacks are the basis to design controllers for appropriate performance, maximum efficiency and minimum degradation. Fluid dynamic models of different dimensions can be found in the literature; however, these models are rarely used to improve the control laws and strategies. This work presents a control oriented 1+1D model (distributed in the direction of the stack flow channels). The model is based on a similar model presented by M. Mangold [1], is implemented in MATLAB Simulink. The model is validated using experimental data of a Powercell stack.
