The increasing world´s energy consumption, especially when related with the exploitation of fossil fuels with the associated emissions, has been introducing adverse global environmental impacts. A possible solution to these issues can derive from the exploitation of alternative source of energy such as the renewable energy systems which, though, introduce issues associated with intermittency and lack of programmability. In order to exploit efficiently and sustainably the energy produced by these sources, the Proton conductor ceramic cells could be employed in order to perform the energy conversion and, this technology, has received in the recent years attention as a promising alternative for clean energy systems also thanks to the lower operating temperatures compared to the most common SOC technologies.
