Abstract
The fuel cell is one of the renewable energy sources and proton exchange membrane (PEM) is the most common and widely used type. With the aim of increasing efficiency, this article first presents a developed PEM fuel cell with additive manufacturing (AM) process. Then, the nonlinear dynamic model describing the behaviour of the AM-based PEM cell is described, and considering the general working class, a new control method for adjusting the pressure of the supply manifold is presented. The planned control method is a combination of model predictive and LMI approaches and in addition to guaranteeing the stability of the closed loop system, it is able to adjust the pressure of the supply manifold and guarantee the optimal operation of the PEM system developed by the additive manufacturing process. The results of simulation and comparison in the MATLAB environment show the efficiency of the proposed control method in meeting the control objectives and improving the transient and permanent response.
