Computational Model of Hydrogen PEM Fuel Cells

This paper deals with the description of the created computational model of hydrogen PEM fuel cells (in the MathLab App Designer software), which are part of the commercially available production module (hydrogen micro-cogeneration unit) FCS 8-XXL manufactured by Nedstack. These specific production units are operated as part of a hybrid energy system in the Laboratory of Hydrogen Technologies of VSB-TUO, where they are used for the energy use of hydrogen gas, which is produced by electrolysis of water fed from available renewable sources (primarily a photovoltaic power plant). The control of the mentioned fuel cells is ensured by a sophisticated control system, which also uses the computational model described here, which enables reliable and safe operation of the low-temperature fuel cell modules integrated into the energy system.
