What is it about?
Here we investigate the viability of using graded TiN films to protect Al sheets from corrosion in environments typical of the ones existing in Proton Exchange Membrane Fuel Cells (PEMFCs). The results show that the films allow to improve considerably the corrosion resistance of Al opening the possibility of using Al as plates in PEMFCs.

Why is it important?
Much has already being said about sustainable environment development. Sustainable development implies maintaining the comfort of present technology while protecting the environment. One of the key aspect of our age is mobility, particularly with automobiles and its is well known that the future is using electrical cars. The development of PEMFCs is one of the ways to achieve this goal and using Al allows to decrease both weight and volume of these components, which is important in the context of mobility.
Perspectives
This is the first work of one of the research lines in my group which promises to be one of the most prolific not only in academic senses, but also in the innovation aspects. Prospecting this research line is an achievement of my coworker, Dr Felipe Carneiro da Silva, who not only identified the potential, but also worked out the connections with the Corrosion Laboratory which was central in this.
