Abstract

The integration of renewable energy–based sourcesinto the electrical power system presents challenges arising from the inherent uncertainty in their generation, particularly in the case of wind or photovoltaic power plants due to their high variability. These challenges can be mitigated through the use of large-scale energy storage systems. Hydrogen emerges as an attractive energy vector with significant development potential; its wide availability, ease of production, storage, and conversion into thermal and electrical energy position it as a feasible solution. However, the potential of hydrogen is not matched by the availability of adequately trained technicians capable of designing, managing, or maintaining facilities in which hydrogen is produced, stored, or transformed to electrical energy. This article presents an educational device developed by the authors, designed to facilitate the understanding and practical application of the process of converting hydrogen into electrical energy through the use of proton exchange membrane fuel cells. The device, which combines low cost, safe operation, and scalability, is currently being used by final-year undergraduate students in the Electrical Engineering degree program, with very satisfactory educational results.

Key words: Energy storage systems, green hydrogen, engineering curricula, renewable energy integration.
