Abstract:

This contribution presents and analyzes modeling and minimum cost operation of proton exchange membrane (PEM) fuel cells and electrolyzers. First, detailed thermoelectric models of the electrochemical technologies based on a first- principle approach are presented. Then, as the detailed nonlinear models developed are intractable for use in online optimal control computation, an efficiently computable mixed integer linear program (MILP) is formulated with linear approximations for the conversion efficiency and temperature of both devices. The outputs of the simplified linear models are compared with the detailed ones, when optimally producing and consuming a fixed quantity of hydrogen gas. Comparisons are performed for a variety of price scenarios and efficiency approximations, for both the fuel cell and electrolyzer.
