Fuel cells have emerged as a sound promising technology for their application in emissions-free generation systems. Their high efficiency, reliability and clean energy make these electrochemical devices specially suitable for manifold applications such as transportation, stationary generation and portable devices. In view of the inherent complexity of this technology, the fuel cell control play a fundamental role to guarantee stability and high performance against system uncertainties and disturbances. Regarding this, sliding mode control has proven to be a powerful technique for the design of robust controllers for generation systems involving fuel cells. However, its discontinuous control action gives rise to some undesired effects when applied to real non-ideal systems, being control chattering usually the main drawback. In this framework, the paper presents the design and experimental implementation of a fuel cell module control via a Switched/Time-Based Adaptive Super-Twisting Algorithm. The designed algorithm is evaluated in a experimental platform of an hybrid generation system based on a commercial 1.2kW fuel cell. The proposed controller exhibits a low value of chattering and similar robustness features compared to traditional Super-Twisting Algorithm.
