In the next incoming years, it is reasonable to expect tremendous changes in the energetic scenario, the intensification of the climate crisis makes necessary strong and rapid transition towards a more sustainable world. Proton conductive cells, PCCs, can represent a possible and valid solution in the future to help a greener energy transition, in particular they rely on already well known and develop technologies, such as PEMs and SOCs, but PCCs combine their major pros, allowing to reach high efficiency at lower operating temperature, simplifying the management of the stack and reducing the impact of possible degradation mechanism. In the last years, the attention for PCCs has grown exponentially, with several studies focused on the development of new materials, long-term stability test, reversible operations, and the possibility to be coupled with different fuels.
