Abstract
This paper proposes a fuzzy logic-based control approach to manage the thermal and fluidic coupling of a Proton Exchange Membrane Fuel Cell (PEMFC) with a Metal Hydride Tank (MHT). The strategy is based on managing the operating temperature of the PEMFC and the hydrogen pressure in the tank. Two PEMFC power modes (static and dynamic) were used to study the performance of this type of control. The main components of the system under study, i.e. the FC, the MHT, and the heat redistribution circuit, were modeled in a Matlab/Simulink environment. The fuzzy logic control used for the proposed system demonstrated good performance under static operating conditions.
