Society is gradually becoming aware that the current energy system, based on the use of fossil fuels is inefficient, highly polluting and finite supply. Within the scientific community and industry stakeholders, there is a unified agreement that indicates that hydrogen (H2), as an energy vector, combined with other sources of alternative energy, represents a safe and viable option to mitigate the problems associated with hydrocarbon combustion, because the entire system can be developed as an efficient, clean and sustainable energy source. In this context, the change from the current energy system to a new system with a stronger involvement of H2 relentlessly involves the introduction of fuel cells as elements of efficient energy conversion.Instituto de Investigaciones en Electrónica, Control y Procesamiento de Señales
